Versatile Interface Processor Functions

The following sections describe the Versatile Interface Processor (VIP) and discuss VIP-speciﬁc

features and functions, such as installing and removing the VIP, installing and removing port

adapters, and using and conﬁguring common VIP interface functions.

What is the VIP?

The VIP is a new interface processor for use with the Cisco 7000 series and Cisco 7500 series

routers, and it installs in the interface processor slots in your Cisco 7000 series or 7500 series router.

The VIP uses a single motherboard with up to two port adapters. The VIP port adapters provide the

individual LAN, WAN, or LAN/WAN interface ports. The VIP can be removed from a chassis while

power is on and the system is operating.

Caution The VIP supports online insertion and removal (OIR), which allows you to remove and

replace a VIP without ﬁrst shutting down the system. Online insertion and removal maximizes router

availability by letting you add or remove VIPs during system operation; however, the system may

indicate a hardware failure if you fail to follow proper procedures. To help avoid problems with the

installation, review the functional description in the section “Online Insertion and Removal—An

Overview” on page 13, and follow the VIP installation steps carefully.

Versatile Interface Processor Functions

Note The VIP port adapters themselves do not support OIR, nor are they FRUs.

The VIP uses a Reduced Instructions Set Computing (RISC), Mips 4600 processor for high

performance, and has an internal operating frequency of 100 megahertz (MHz) and a 50-MHz

system bus interface. The VIP has 8 megabytes (MB) of dynamic random access memory (DRAM)

as the default DRAM configuration.

Figure 1 shows a VIP-FE-TX/4E. The VIP ﬁrmware (microcode), which contains card-speciﬁc

software instructions, resides in a Flash memory device in socket location U17. For pinouts, refer to

the section “FE-TX Port Adapter Receptacles, Cables, and Pinouts” on page 33. Single in-line

memory modules contain the DRAM. You can install VIPs in any available interface processor slots

in your Cisco 7000 or Cisco 7500 series router.

on each port adapter’s faceplate.

Caution To prevent system problems, do not remove port adapters from the VIP motherboard or

attempt to install other port adapters on the VIP motherboard.

VIP Microcode Overview

The VIP microcode (ﬁrmware) is an image that provides card-speciﬁc software instructions. A Flash

memory device in socket U17 of the VIP contains the default microcode boot image. The router

supports downloadable microcode, which enables you to upgrade microcode versions by

downloading new microcode images, storing them in system Flash memory, and instructing the

system to load its image from Flash instead of the default VIP image. (The RP in the Cisco 7000 and

7010 loads software from ROM or Flash memory; the RSP loads software from Flash only.) You can

store multiple images for an interface type and, with a conﬁguration command, instruct the system

to load any one of them or the default ROM image. All interfaces of the same type (VIP, and so on)

will load the same microcode image, either from the default ROM image or from a single image

stored in system Flash. Although multiple microcode versions for a speciﬁc interface type can be

stored concurrently in Flash, only one image can load at startup. The show controllers cbus

command displays the currently loaded and running microcode version for the SP or SSP (in the

Cisco 7000 series routers), each interface processor, and VIP. The show startup-conﬁg EXEC

command shows the current system instructions for loading microcode at startup.

Software and interface processor microcode images are carefully optimized and bundled to work

together. Overriding the bundle can result in system incompatibilities. We recommend that you use

the microcode included in the software bundle. For a complete description of microcode and

downloading procedures, refer to the section “Upgrading VIP Microcode” on page 23.

VIP Installation Prerequisites

This section provides a list of parts and tools you will need to perform the installation, and it also

includes safety and ESD-prevention guidelines to help you avoid injury and damage to the

equipment. This section also provides a detailed description of the OIR function to help you perform

online installation successfully and avoid error message and system restarts. If you are installing a

new VIP, be sure to review the equipment descriptions and distance limitations in the section

“FE-TX Port Adapter Receptacles, Cables, and Pinouts” on page 33 when preparing your site and

planning network connections.

List of Parts and Tools

You need the following tools and parts to install a VIP. If you need additional equipment, contact a

service representative for ordering information.

• Cables appropriate for the port adapter interfaces on your VIP

• Number 1 Phillips and a 3/16-inch, ﬂat-blade screwdriver

• Your own ESD-prevention equipment or the disposable grounding wrist strap included with all

upgrade kits, FRUs, and spares

Safety Guidelines

Following are safety guidelines that you should follow when working with any equipment that

connects to electrical power or telephone wiring.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergency

power-off switch for the room in which you are working.

• Disconnect all power and external cables before moving a chassis.

• Do not work alone when potentially hazardous conditions exist.

• Never assume that power has been disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes the equipment

unsafe.

• Carefully examine your work area for possible hazards such as moist ﬂoors, ungrounded power

extension cables, and missing safety grounds.

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone

wiring or to other network cabling:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is speciﬁcally designed for wet

locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been

disconnected at the network interface.

• Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are

improperly handled, results in complete or intermittent failures. A processor module comprises a

printed circuit board that is ﬁxed in a metal carrier. Electromagnetic interference (EMI) shielding,

connectors, and a handle are integral components of the carrier. Although the metal carrier helps to

protect the board from ESD, use a preventive antistatic strap whenever handling a processor module.

Following are guidelines for preventing ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to a captive installation screw on an installed power

supply.

• When installing a processor module, use the ejector levers to properly seat the bus connectors in

the backplane, then tighten both captive installation screws. (See Figure 8.) These screws prevent

accidental removal, provide proper grounding for the system, and help to ensure that the bus

connectors are seated in the backplane.

• When removing a processor module, use the ejector levers to release the bus connectors from the

backplane. Use the handle to pull the processor module out slowly while keeping your other hand

underneath the carrier to guide it straight out of the slot.

Versatile Interface Processor Functions

• Handle carriers by the handles and carrier edges only; avoid touching the board or connectors.

• Place a removed processor module board-side-up on an antistatic surface or in a static shielding

bag. If you plan to return the component to the factory, immediately place it in a static shielding

bag.

• Avoid contact between the processor module and clothing. The wrist strap only protects the board

from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal interface processor carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The

measurement should be between 1 and 10 megohms.

Online Insertion and Removal—An Overview

The OIR feature allows you to remove and replace a VIP board while the system is operating; you

do not need to notify the software or shut down the system power.

Note The VIP port adapters themselves do not support OIR, nor are they FRUs.

This section describes mechanical functions of system components, emphasizes the importance of

following correct procedures to avoid unnecessary board failures, and is for background only;

speciﬁc VIP procedures follow in the section “VIP Installation” on page 16.

Each interface processor contains a receptacle with which it connects to the system backplane. Each

backplane connector comprises a set of tiered pins, in three lengths. The pins send speciﬁc signals

to the system as they make contact with the card. The system assesses the signals it receives and the

order in which it receives them to determine what event is occurring and what task it needs to

perform, such as reinitializing new interfaces or shutting down removed ones.

For example, when inserting an interface processor, the longest pins make contact with the

backplane ﬁrst, and the shortest pins make contact last. The system recognizes the signals and the

sequence in which it receives them. The system expects to receive signals from the individual pins

in this logical sequence, and the ejector levers help to ensure that the pins mate in this sequence.

When you remove or insert an interface processor, the backplane pins send signals to notify the

system, which then performs as follows:

Rapidly scans the backplane for conﬁguration changes and does not reset any interfaces.

Initializes all newly inserted interface processors, noting any removed interfaces and placing

them in the administratively shut down state.

Brings all previously conﬁgured interfaces on the interface processor back to the state they were

in when they were removed. Any newly inserted interfaces are put in the administratively shut

down state, as if they were present (but unconﬁgured) at boot time. If a similar interface processor

type has been reinserted into a slot, then its ports are conﬁgured and brought on line up to the

port count of the original interface processor.

Versatile Interface Processor Functions

The system brings on line only interfaces that match the current conﬁguration and were previously

conﬁgured as up; all others require that you conﬁgure them with the conﬁgure command. OIR

functionality enables you to add, remove, or replace interface processors with the system online,

which provides a method that is seamless to end users on the network, maintains all routing

information, and ensures session preservation.

The function of the ejector levers (see Figure 8) is to align and seat the card connectors in the

backplane. Failure to use the ejector levers and insert the interface processor properly can disrupt the

order in which the pins make contact with the card or interface processor. Follow the VIP installation

and removal instructions carefully, and review the following examples of incorrect insertion

practices and their results:

• Using the handle to force the interface processor all the way into the slot can pop the ejector

levers out of their springs. If you then try to use the ejector levers to seat the interface processor,

the ﬁrst layer of pins (which are already mated to the card or interface processor) can disconnect

and then remate with the backplane, which the system interprets as a board failure.

• Using the handle to force or slam the interface processor all the way into the slot can damage the

pins on the board connectors if they are not aligned properly with the backplane.

• When using the handle (rather than the ejector levers) to seat the interface processor in the

backplane, you might need to pull the interface processor back out and push it in again to align

it properly. Even if the backplane pins are not damaged, the pins mating with and disconnecting

from the card or interface processor will cause the system to interpret a board failure. Using the

ejector levers ensures that the board connector mates with the backplane in one continuous

movement.

• Using the handle to insert or remove an interface processor, or failing to push the ejector levers

fully against the interface processor, can leave some (not all) of the connector pins mated to the

card or interface processor, a state which will hang the system. Using the ejector levers and

making sure that they are pushed fully into position ensures that all three layers of pins are mated

with (or free from) the backplane.

It is also important to use the ejector levers when removing an interface processor to ensure that the

backplane connector pins disconnect from the card or interface processor in the logical sequence

expected by the system. Any interface processor that is only partially connected to the backplane can

hang the bus. Detailed steps for correctly performing OIR are included with the following

procedures for installing and removing the VIP.

Versatile Interface Processor Functions

VIP Installation

The following sections describe the procedures for removing or installing a VIP in the Cisco 7000

series and Cisco 7500 series routers. The functionality is the same for each router model; therefore,

the term the chassis will be used except where speciﬁc model issues arise. The OIR function allows

you to install and remove a VIP without ﬁrst shutting down the system; however, you must follow

the instructions carefully. Failure to insert the VIP properly can cause system error messages

indicating a board failure. For a complete description of OIR, refer to the section “Online Insertion

and Removal—An Overview” on page 13.

Each unused interface processor slot contains an interface processor ﬁller (which is an interface

processor carrier without an interface board) to keep dust out of the chassis and to maintain proper

air ﬂow through the interface processor compartment. If you are installing a new VIP that is not a

replacement, you must ﬁrst remove the interface processor ﬁller from an unused slot; proceed to the

next section “Removing an Interface Processor Filler.” If you are replacing a VIP or upgrading the

microcode Flash EPROM on a VIP, proceed to the section “Removing a VI P .”

Note If you suspect that a port adapter has failed, you must replace the entire VIP processor

module. Port adapters are not available as FRUs.

Caution If you use the VIP with a single port adapter, the port adapter must be in slot 0 for the VIP

to function properly. A single port adapter in slot 1 will not be recognized by the system.

Removing an Interface Processor Filler

Select an unused interface processor slot for the new VIP and remove the interface processor ﬁller

as follows:

Step 1 Choose an available slot for the VIP and make a note of it.

Step 1 Use a screwdriver to loosen the captive installation screws on the interface processor ﬁller.

(See Figure 8.)

Step 2 Place your thumbs on both ejector levers and simultaneously pull them both outward to

release the VIP from the backplane connector (in the opposite direction from that shown in

Figure 8c).

Step 3 Grasp the handle with one hand and pull the ﬁller straight out of the slot, keeping your other

hand under the carrier to guide it. (See Figure 9.) Keep the carrier parallel to the backplane.

Step 4 Store the interface processor ﬁller for future use.

To help prevent dust and contaminants from entering the chassis, do not leave the interface processor

slot open. Immediately proceed to the section “Installing a VIP” on page 18.

Removing a VIP

Remember, the VIP supports OIR; therefore, you need not shut down the interface or the system

power when removing a VIP. If you are replacing a failed VIP, remove the existing board ﬁrst, then

replace the new VIP in the same slot.

To remove a VIP, follow these steps:

Step 1 If you are replacing a failed VIP, disconnect all cables from the VIP ports; however, if you

are only moving a VIP to another slot, this step is not necessary.

Step 2 Use a screwdriver to loosen the captive installation screws at both ends of the VIP.

(See Figure 8.)

Caution Always use the ejector levers to remove or install the VIP. Failure to do so can cause

erroneous system error messages indicating a board failure.

Step 3 Place your thumbs on the ejector levers and simultaneously pull both of the ejectors

outward (in the opposite direction from that show in Figure 8c) to release the VIP from the

backplane connector.

Step 4 Use the VIP handle to carefully pull the VIP straight out of the slot, keeping your other

hand under the carrier to guide it. (See Figure 9.) Keep the VIP parallel to the backplane.

Step 5 Place the removed VIP on an antistatic mat or foam pad, or place it in an antistatic bag if

you plan to return it to the factory.

Step 6 If the interface processor slot is to remain empty, install a ﬁller (MAS7K-BLANK) to keep

dust out of the chassis and to maintain proper air ﬂow inside the chassis. Do not leave the

interface processor slot open. Immediately proceed to the section “Installing a VI P .”

Versatile Interface Processor Functions

Installing a VIP

The VIP slides into the open interface processor slot and connects directly to the backplane. The

interface processors are keyed to guide pins on the backplane, so the VIP can be installed only in an

interface processor slot. Figure 8 shows the functional details of inserting an interface processor and

using the ejector levers. Figure 9 shows proper handling of an interface processor during installation.

Caution Remove or insert only one interface processor at a time. Allow at least 15 seconds for the

system to complete its discovery and initialization before removing or inserting another interface

processor. Disrupting the sequence before the system has completed veriﬁcation can cause the

system to interpret hardware failures.

Follow these steps to install a VIP:

Step 1 Ensure that a console terminal is connected to the console port (on the RP or RSP) and that

your console is turned ON.

Step 2 Hold the VIP handle with one hand and place your other hand under the carrier to support

the VIP and guide it into the slot. (See Figure 9.) Avoid touching the card or any connector

pins.

Caution To prevent ESD damage, handle interface processors by the handles and carrier edges

only.

Note The processor modules are oriented horizontally in the Cisco 7010 and Cisco 7505, and

vertically in the Cisco 7000, the Cisco 7507, and the Cisco 7513.

Step 3 Place the back of the VIP in the slot and align the notch on the carrier with the groove in

the slot. (See Figure 8.)

Step 4 While keeping the VIP parallel to the backplane, carefully slide it into the slot until the back

of the faceplate makes contact with the ejector levers, then stop. (See Figure 8b.)

Caution Always use the ejector levers when installing or removing processor modules. A module

that is partially seated in the backplane will cause the system to hang and subsequently crash, and

shoving or slamming the interface processor into the slot can damage the backplane pins and board.

Step 5 Using your thumbs, simultaneously push both ejector levers inward until the VIP is pushed

entirely into its slot. (See Figure 8c.)

Step 6 To ensure that EMI shielding is properly maintained for the chassis, immediately tighten

both of the captive installation screws.

Checking the Installation and Verifying VIP Status

You can use the conﬁgure command to conﬁgure a VIP interface. To use the conﬁgure command,

enter the privileged level of the EXEC command interpreter with the enable command. The system

will prompt you for a password if one has been set.

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket

(>). At the console terminal, enter the privileged level as follows:

Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a

privileged-level password, as follows:

Router> enable

Password:

Step 2 Enter the password (the password is case sensitive). For security purposes, the password is

not displayed on your console.

Step 3 When you enter the correct password and press Return, the system displays the

privileged-mode system prompt (#) as follows:

Router#

Checking the VIP Installation

After you install the VIP and connect cables (using connection procedures in the respective port

adapter subsections), verify the installation by observing the LED states and the console display.

When the system has reinitialized all interfaces, the enabled LED on the VIP and on all interface

processors should go on. One or the other of the MII and RJ-45 LEDs should be on, depending on

your connection, and the link LED should be on if the VIP is receiving a carrier signal from the

network.

The console screen will also display a message as the system discovers each interface during its

reinitialization.

When you remove and replace interface processors, the system provides status messages on the

console screen. The messages are for information only.

Note Fast Ethernet interfaces are used in the following examples.

The following sample display shows the events logged by the system as a Fast Ethernet-equipped

VIP was removed from slot 2; the system then reinitialized the remaining interface processors and

marked as down the Fast Ethernet interfaces on the VIP that was removed from slot 2. When the VIP

is reinserted, the system automatically brings up the interfaces that were up when the VIP was

removed.

Versatile Interface Processor Functions

Note When a new VIP is inserted or when a VIP is moved to a new slot, the system recognizes the

new interfaces, but leaves them in a shutdown state until you conﬁgure them and change their state

to up with the conﬁgure command.

The following example display shows the events logged by the system as a new VIP is inserted in

slot 3.

Router#

%OIR-6-INSCARD: Card inserted in slot 3, interfaces administratively shut down

%LINK-5-CHANGED: Interface FastEthernet3/0/0, changed state to administratively down

Verify that the VIP is installed correctly as follows:

Step 1 While the system reinitializes each interface, observe the console display messages and

verify that the system discovers the VIP as follows:

• If you installed a new VIP, the system should recognize all new Fast Ethernet interfaces

but leave them conﬁgured as down.

• If you replaced a VIP, the system should recognize each interface and place it in the

same state (up or down) each was in when you removed the VIP.

Step 2 When the reinitialization is complete, verify that the enabled LED on each port adapter

goes on and remains on. If it does, proceed to step 5. If it does not, proceed to the next step.

Step 3 If the enabled LED on a port adapter fails to go on, suspect that the VIP board connector is

not fully seated in the backplane. Loosen the captive installation screws, then ﬁrmly push

both ejector levers into place until they are approximately in the same orientation as the VIP

faceplate. Tighten the captive installation screws. After the system reinitializes the

interfaces, the enabled LED on the port adapter should go on. If it does, proceed to step 5.

If it does not, proceed to step 4.

Step 4 If the enabled LED still fails to go on, remove the VIP and try installing it in another

available interface processor slot.

• If the enabled LED goes on when the VIP is installed in the new slot, suspect a failed

backplane port in the original interface processor slot.

• If the enabled LED still fails to go on, but other LEDs on the VIP go on to indicate

activity, proceed to step 5 to resume the installation checkout and suspect that the

enabled LED on the port adapter has failed.

• If no LEDs on the VIP go on, suspect that the VIP is faulty.

• If the enabled LED still does not go on, do not proceed with the installation. Contact a

service representative to report the problem and obtain further instructions.

Step 5 If the VIP is new and not a replacement, you have to conﬁgure the new interfaces. Proceed

to the appropriate conﬁguration section for your port adapter. (This does not have to be

done immediately, but new interfaces will not be available until you conﬁgure them.)

Step 6 If the VIP is a replacement, use the show interfaces type slot/port adapter/port or show

controllers cbus command to verify the status of the interfaces. (Refer to the section

“V e rifying VIP Status Using show Commands” on page 21.)

If you replaced a VIP with a new VIP with a greater number of ports (for example, if you

replaced a one-port VIP with a two-port VIP), the system will recognize the ﬁrst interface,

but will not recognize the additional interface. The new interface will remain in the

shutdown state until you conﬁgure it.

Versatile Interface Processor Functions

Step 7 When the interfaces are up, check the activity of each interface by observing the status

LEDs, which are described in the appropriate LED section for your port adapter type.

Step 8 In general, if an interface’s LED fails to go on and a cable is connected to the port, check

the cable connection and make certain it is properly seated in the connector.

If an error message is displayed on the console terminal, refer to the System Error Messages

publication for error message deﬁnitions. If you experience other problems that you are unable to

solve, contact a service representative for assistance.

This completes the VIP installation. If you installed a new VIP or if you installed a replacement VIP

with an additional port, you must now conﬁgure the new interface as described in the following

section.

Verifying VIP Status Using show Commands

The following procedure describes how to use the show commands to verify that the new interfaces

are conﬁgured correctly:

Step 1 Use the show version or show hardware commands to display the system hardware

conﬁguration. Ensure that the list includes the new Fast Ethernet interfaces.

Step 2 Display all of the current interface processors and their interfaces with the show

controllers cbus command. Verify that the new VIP appears in the correct slot.

Step 3 Specify one of the new VIP interfaces with the show interfaces type slot/port adapter/port

command and verify that the ﬁrst line of the display speciﬁes the interface with the correct

slot number. Also verify that the interface and line protocol are in the correct state: up or

down.

Step 4 Display the protocols conﬁgured for the entire system and speciﬁc interfaces with the

command show protocols. If necessary, return to the Conﬁguration mode to add or remove

protocol routing on the system or speciﬁc interfaces.

Step 5 Display the entire system conﬁguration ﬁle with the show conﬁguration command. Verify

that the conﬁguration is accurate for the system and each interface.

If the interface is down and you conﬁgured it as up, or if the displays indicate that the hardware is

not functioning properly, ensure that the network interface is properly connected and terminated. If

you still have problems bringing the interface up, contact a service representative for assistance.

The show controllers cbus command displays the internal status of each interface processor,

including the slot location, the card hardware version, and the currently-running microcode version.

It also lists each interface (port) on each interface processor including the logical interface number,

interface type, physical (slot/port adapter/port) address, and hardware (station address) of each

Versatile Interface Processor Functions

Upgrading VIP Microcode

The Cisco 7000 series and the Cisco 7500 series support downloadable microcode, which enables

you to upgrade microcode versions without having to physically replace the microcode Flash

memory device on the board. You can download new microcode versions and store multiple versions

in Flash memory, and you can boot from them just as you can with the system software images.

System software upgrades may also contain upgraded microcode images, which will load

automatically when the new software image is loaded (unless the conﬁguration states otherwise).

Note Software and interface processor microcode images are carefully optimized and bundled to

work together. Overriding the bundle can result in system incompatibilities. We recommend that you

use the microcode included in the software bundle.

You can download microcode to Flash memory by copying the TFTP image of a microcode version

to Flash memory. When the microcode image is stored in Flash memory you can use the

microcode reload command to manually load the new microcode ﬁle, and the conﬁgure command

to instruct the system to load the new image automatically at each system boot.

To compare the size of the microcode image and the amount of Flash memory available, you must

know the size of the new microcode image. The image size is speciﬁed in the README ﬁle that is

included on the ﬂoppy disk with the new image.

Note Note the size of the new image before proceeding to ensure that you have sufﬁcient available

Flash memory for the new image.

Caution Before you copy a ﬁle to system Flash memory, be sure there is ample space available in

Flash memory. Compare the size of the ﬁle you want to copy to the amount of available Flash

memory shown. If the space available is less than the space required by the ﬁle you want to copy,

the copy process will continue, but the entire ﬁle will not be copied into Flash memory.

Versatile Interface Processor Functions

Follow these steps to download (copy) a microcode version from a TFTP server to Flash memory.

Step 1 To display the total amount of Flash memory present, its location, any ﬁles that currently

exist in Flash memory and their size, and the amount of Flash memory remaining, use the

show ﬂash command. Following is an example of the output that is displayed:

Router# show flash

-#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name

.. FFFFFFFF B4A18E0B 3F6494 30

111518 Jun 29 1994 11:05:57 image/file/2

12044568 bytes available (8533736 bytes used)

Step 2 Compare the amount of available Flash memory (last line in the preceding example) to the

size of the new microcode image on the ﬂoppy disk. If you attempt to copy in a new image,

and the size of the new image exceeds the available space in Flash, only part of the new

image will be copied, and the following error message will be displayed:

buffer overflow - xxxx/xxxx

where xxxx/xxxx is the number of bytes read in/number of bytes available.

Step 3 After you verify that there is sufﬁcient space available in Flash memory for the new image,

use the command copy tftp:ﬁlename [ ﬂash | slot0 | slot1 ]:ﬁlename to copy an image to

Flash memory. (tftp:ﬁlename is the ﬁle’s source, and [ ﬂash | slot0 | slot1 ]:ﬁlename is the

destination in onboard Flash memory or on either of the Flash memory cards.)

An example of the copy tftp:ﬁlename command follows:

Router# copy tftp:vip11-1 slot0:vip11-1

Step 4 Use the show ﬂash command to verify that the microcode has been copied to Flash. The

output should display the ﬁlename of the image you copied to Flash (vip11-1 in the

following example):

Step 5 To ensure that the new microcode is used when you reboot the system, add the appropriate

commands to the conﬁguration ﬁle. To modify the conﬁguration ﬁle, enter the conﬁgure

terminal command, as follows:

Router# config t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

Step 6 Specify that you are changing the microcode for the VIP (microcode vip), and that it will

load from Flash memory (ﬂash). Then add the ﬁlename of the new microcode image to be

loaded from Flash:

Router(config)# microcode vip flash slot0:vip11-1

Step 7 To save the conﬁguration ﬁle, press Ctrl-Z.

Step 8 Copy the new conﬁguration to nonvolatile random-access memory (NVRAM):

Router# copy running-config startup-config

The microcode reload command is automatically added to your running conﬁguration.

The new VIP microcode image will load automatically the next time the system boots or

reinitializes.

Step 9 To load the new microcode immediately, you can issue the microcode reload conﬁguration

command (you must be in Conﬁguration mode to enter this command):

Router# config t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)# microcode reload

Immediately after you enter the microcode reload command and press Return, the system

reloads all microcode. Conﬁguration mode remains enabled; after the reload is complete,

press Ctrl-Z to exit from Conﬁguration mode and return to the system prompt.

Step 10 To verify that the VIP is using the correct microcode, issue the show startup-conﬁg or

show controllers cbus command, which indicates the currently loaded and running

microcode version for each interface processor and the SP or SSP in the Cisco 7000 series

routers.

Router# show controllers cbus

This completes the procedure for downloading microcode to Flash memory.

Upgrading and Replacing DRAM SIMMs

VIPs are shipped with 8 MB of DRAM as the default memory conﬁguration. Depending on memory

requirements, you might need to upgrade the amount of DRAM by replacing the DRAM SIMMs on

the VIP. You also might need to replace a single SIMM in the case of a diagnosed DRAM SIMM

failure.

Note DRAM SIMMs should be upgraded or replaced in the ﬁeld by a Cisco-certiﬁed maintenance

provider. Both DRAM SIMMs are replaced for all upgrades.

Caution SIMMs are sensitive components that are susceptible to ESD damage. Handle SIMMs by

the edges only; avoid touching the memory modules, pins, or traces (the metal ﬁngers along the

connector edge of the SIMM). (See Figure 10.)

Following is the procedure for replacing or upgrading DRAM SIMMs.

Step 1 Attach an ESD-preventive wrist strap between you and an unpainted chassis or VIP surface.

Step 2 Disconnect all cables from the VIP and remove it from the chassis using the procedure in

the section “Removing a VIP” on page 16.

Step 3 Place the VIP on a ﬂat surface (preferably an antistatic mat or foam), and turn it so the face

plate is away from you and the connector edge is toward you. (approximately opposite of

the orientation shown in Figure 11).

Step 7 Insert the new SIMM by sliding the end with the metal ﬁngers into the SIMM connector

socket at approximately a 45-degree angle to the system card. Gently rock the SIMM back

into place until the latch on either side snaps into place. (See Figure 12.)

Caution Do not use excessive force, or the connector could break. To prevent damage, do not push

on the center of the SIMMs. Handle each SIMM with care.

Step 8 As required, repeat Steps 5 through 7 for the second SIMM.

Step 9 Reinstall the VIP in the chassis using the procedure in the section “Installing a VIP” on

page 18.

If error messages relating to memory are displayed once power to the chassis is turned back on, or

the VIP card is installed in a chassis that is already on, repeat Steps 1 through 8, taking care to ﬁrmly

reseat each SIMM in its socket.

This completes the procedure for upgrading or replacing DRAM SIMMs on your VIP.

Fast Ethernet Overview

The VIP conﬁgured with two FE-TX port adapters provides up to two 100-Mbps, 100BASE-T, Fast

Ethernet interfaces. Each 100BASE-T port on the FE-TX port adapter has an RJ-45 connector to

attach to Category 5 unshielded twisted-pair (UTP) for 100BASE-TX, and a MII connector that

permits connection through external transceivers to multimode ﬁber for 100BASE-FX, or to

Category 3, 4, and 5 UTP or shielded twisted-pair (STP) for 100BASE-T4 physical media. Both

full-duplex and half-duplex operation are supported.The term Ethernet is commonly used for all

carrier sense multiple access/collision detection (CSMA/CD), local-area networks (LANs) that

generally conform to Ethernet speciﬁcations, including IEEE 802.3u.

Note 100BASE-TX is intended for Environment A and 100BASE-FX is intended for

Environment B.

IEEE 802.3u is well suited to applications where a local communication medium must carry

sporadic, occasionally heavy trafﬁc at high peak data rates. Stations on a CSMA/CD LAN can access

the network at any time. Before sending data, the station listens to the network to see if it is already

in use. If it is, the station waits until the network is not in use, then transmits; this is half-duplex

operation. A collision occurs when two stations listen for network trafﬁc, hear none, and transmit

very close to simultaneously. When this happens, both transmissions are damaged, and the stations

must retransmit.

VIP-FE-TX/4E Installation and Configuration 29

Download from Www.Somanuals.com. All Manuals Search And Download.

VIP Port Adapter Functions

The stations detect the collision and use backoff algorithms to determine when they should

retransmit. Both Ethernet and IEEE 802.3u are broadcast networks, which means that all stations see

all transmissions. Each station must examine received frames to determine whether it is the intended

destination and, if it is, pass the frame to a higher protocol layer for processing.

Each physical layer protocol has a name that summarizes it characteristics in the format

speed/signaling method/segment length where speed is the LAN speed in megabits per second

(Mbps), signaling method is the signaling method used (either baseband or broadband), and segment

length is typically the maximum length between stations in hundreds of meters. Therefore,

100BASE-T speciﬁes a 100-Mbps, baseband LAN with maximum network segments of 100 meters

(or 400 meters for 100BASE-FX).

IEEE 802.3u speciﬁes the following different physical layers for 100BASE-T:

• 100BASE-TX—100BASE-T, half and full duplex over Category 5 unshielded twisted-pair

(UTP), Electronics Industry Association/Telecommunications Industry Association

[EIA/TIA]–568-compliant cable

• 100BASE-FX—100BASE-T, half and full duplex over optical ﬁber

• 100BASE-T4—100BASE-T, half and full duplex over Category 3, 4, or 5 UTP or shielded

twisted-pair (STP) cabling with four pairs; also called 4T+ or T2, which is 2-pair UTP over

Category 3 cable.

FE-TX Port Adapter LEDs

The FE-TX port adapter contains the enabled LED, standard on all port adapters, and a bank of three

status LEDs for the ports. After system initialization, the enabled LED goes on to indicate that the

FE-TX port adapter has been enabled for operation. (The LEDs are shown in Figure 15.) The

following conditions must be met before the enabled LED goes on:

• The FE-TX interface is correctly connected to the backplane and receiving power.

• The FE-TX-equipped VIP contains a valid microcode version that has been downloaded

successfully.

• The bus recognizes the FE-TX-equipped VIP.

If any of these conditions is not met, or if the initialization fails for other reasons, the enabled LED

does not go on.

• Link—When the RJ-45 port is active, this LED is on when the FE-TX port adapter is receiving

a carrier signal from the network. When the MII port is active, this LED is an indication of

network activity, and it ﬂickers on and off proportionally to this activity.

• RJ-45—On when the RJ-45 port is selected as the active port by the controller.

Either the MII LED or the RJ-45 LED should be on at any one time; never both.

Figure 15 LEDs on the FE-TX Port Adapter (Horizontal Orientation Shown)

Note The VIP is oriented horizontally in the Cisco 7010 and Cisco 7505, and vertically in the Cisco

7000, the Cisco 7507, and the Cisco 7513.

FE-TX Port Adapter Receptacles, Cables, and Pinouts

The two interface receptacles on the FE-TX port adapter are a single MII, 40-pin, D-shell type, and

a single RJ-45. You can use either one or the other. Only one receptacle can be used at one time. Each

connection supports IEEE 802.3u interfaces compliant with the 100BASE-X and 100BASE-T

standards. The RJ-45 connection does not require an external transceiver. The MII connection

requires an external physical sublayer (PHY) and an external transceiver.

Figure 16 sho ws the RJ-45 connectors. Table 3 lists the pinouts and signals for the FE-TX RJ-45

connectors.

Warning The ports labeled “Ethernet,” “10BaseT,” “Token Ring,” “Console,” and “AUX” are

safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV

circuits. Because the BRI circuits are treated like telephone-network voltage, avoid connecting the

SELV circuit to the telephone network voltage (TNV) circuits. (For translated versions of this

Note Referring to the RJ-45 pinout in Table 3, proper common-mode line terminations should be

used for the unused Category 5, UTP cable pairs 4/5 and 7/8. Common-mode termination reduces

the contributions to electromagnetic interference (EMI) and susceptibility to common-mode

sources. Wire pairs 4/5 and 7/8 are actively terminated in the RJ-45, 100BASE-TX port circuitry in

the FE-TX port adapter.

Depending on your RJ-45 interface cabling requirements, use the pinouts in Figure 17 and

VIP Port Adapter Functions

The MII receptacle uses 2-56 screw-type locks, called jackscrews (shown in Figure 19), to secure

the cable or transceiver to the MII port. MII cables and transceivers have knurled thumbscrews

(screws you can tighten with your ﬁngers) that you fasten to the jackscrews on the FE-TX port

adapter’s MII connector. Use the jackscrews to provide strain relief for your MII cable. (The RJ-45

modular plug has strain relief functionality incorporated into the design of its standard plastic

connector.) Figure 19 shows the MII female connector.

VIP Port Adapter Functions

Attaching FE-TX Port Adapter Interface Cables

On a single 100BASE-T port adapter, you can use either the RJ-45 connection or the MII

connection. If you have two FE-TX, 100BASE-T port adapters on your VIP, you can use the RJ-45

connection on one and the MII connection on the other.

Note RJ-45 and MII cables are not available from Cisco Systems; they are available from outside

commercial cable vendors.

Connect RJ-45 and MII cables as follows:

Step 1 If you have RJ-45 connections, attach the Category 5 UTP cable directly to the RJ-45 port

on the FE-TX port adapter. (See Figure 20.)

If you have MII connections, attach an MII cable directly to the MII port on the FE-TX port

adapter or attach a 100BASE-T transceiver, with the media appropriate to your application,

to the MII port on the FE-TX port adapter. (See Figure 20.)

The FE-TX port adapter is an end station device and not a repeater. You must connect the

FE-TX port adapter to a repeater or hub.

Note The FE-TX and 4E port adapters have a handle attached, but this handle is not shown to allow

a full view of detail on each port adapter’s faceplate.

Step 2 Attach the ferrite bead to the RJ-45 cable (at either end), as shown in Figure 21.

Caution The ferrite bead prevents electromagnetic interference (EMI) from affecting the

FE-TX-equipped system and is a required component for proper system operation.

Figure 21 Attaching the Ferrite Bead around the RJ-45 Cable

Caution To prevent problems on your FE-TX port adapter and network, do not simultaneously

connect RJ-45 and MII cables to one 100BASE-T port adapter. On a single 100BASE-T port

adapter, only one network connection can be used at one time. Only connect cables that comply with

EIA/TIA-568 standards. (Refer to Table 1 and T able 2 on page 32 for cable recommendations and

speciﬁcations.)

Step 3 Attach the network end of your RJ-45 or MII cable to your 100BASE-T transceiver, switch,

hub, repeater, DTE, or other external 100BASE-T equipment.

This completes the FE-TX installation. Proceed to the section “Checking the VIP Installation.”

Conﬁguring the FE-TX Interface

If you installed a new FE-TX interface or if you want to change the conﬁguration of an existing

interface, you must enter Conﬁguration mode, using the conﬁguration command. If you replaced

an interface that was previously conﬁgured, the system will recognize the new interface and bring it

up in its existing conﬁguration.

After you verify that the new FE-TX is installed correctly (the enabled LED goes on), use the

privileged-level conﬁgure command to conﬁgure the new interfaces. Be prepared with the

information you will need, such as the following:

• Protocols you plan to route on each new interface.

• Internet protocol (IP) addresses if you plan to conﬁgure the interfaces for IP routing.

• Whether the new interfaces will use bridging.

Note For a summary of the conﬁguration options available and instructions for conﬁguring the

FE-TX interfaces on the VIP, refer to the publications listed in the section “If Y o u Need More

Information” on page 2.

VIP Port Adapter Functions

Note The conﬁgure command requires privileged-level access to the EXEC command interpreter,

which usually requires a password. Contact your system administrator, if necessary, to obtain

EXEC-level access.

Selecting Chassis Slot, Port Adapter, and Fast Ethernet Interface Port Numbers

The following section describes how to identify chassis slot, port adapter, and Fast Ethernet interface

port numbers.

Note Although the processor slots in the seven-slot Cisco 7000 and 13-slot Cisco 7513 are

vertically oriented and those in the ﬁve-slot Cisco 7010 and Cisco 7505 are horizontally oriented, all

models use the same method for slot and port numbering. (Refer to Figure 2, Figure 3, Figure 4,

Figure 5, or Figure 6 for interface processor slot orientation in your chassis.)

In the router, physical port addresses specify the actual physical location of each interface port on

the router interface processor end. (See Figure 22.) This address is composed of a three-part number

in the format chassis slot number/port adapter number/interface port number.

The ﬁrst number identiﬁes the chassis slot in which the VIP is installed (as shown in the example

system in Figure 22). The second number identiﬁes the physical port adapter number on the VIP, and

is either 0 or 1. The interface ports on each FE-TX port adapter are always numbered as interface 0.

Interface ports on the VIP maintain the same address regardless of whether other interface

processors are installed or removed. However, when you move a VIP to a different slot, the ﬁrst

number in the address changes to reﬂect the new slot number.

VIP Port Adapter Functions

Figure 22 shows some of the slot port adapter and interface ports of a sample Cisco 7505 system.

For example, on a FE-TX/FE-TX VIP in slot 3, the address of the ﬁrst Fast Ethernet port adapter is

3/0/0 (chassis slot 3, port adapter slot 0, and interface port 0), and the address of the second Fast

Ethernet port adapter is 3/1/0 (chassis slot 3, port adapter slot 1, and interface port 0).

The individual port adapter numbers are always 0 and 1. The individual interface port numbers

always begin with 0. For example, the FE-TX port adapters in the ﬁrst and second port adapter slots

in chassis slot 3 would have the following addresses: 3/0/0 and 3/1/0. The number of additional ports

depends on the number of ports on a port adapter.

Note If you remove the VIP from slot 3 and install it in slot 2, the addresses of those same ports

become 2/0/0 and 2/1/0.

Note: The MII and RJ-45 interface ports on the first port adapter are both

numbered as interface port 0. Only one of them can be used on each port adapter,

at one time.

You can identify interface ports by physically checking the slot/port adapter/interface port location

on the back of the router or by using software commands to display information about a speciﬁc

interface or all interfaces in the router.

To display information about a speciﬁc interface, use the show interfaces command with the

interface type and port address in the format show interfaces [type slot/port adapter/port].

Following is an example of how the show interfaces command displays status information

(including the physical slot and port address) for the interface you specify. In this example, most of

the status information for each interface is omitted, and a Fast Ethernet interface in slot 3 is used.

VIP Port Adapter Functions

Fast Ethernet interface port adapters are numbered from 0 and 1 because VIPs support up to two

100BASE-T ports. The MII and RJ-45 ports on a port adapter each have the same port number

because only one of them can be used at one time.

Refer to Table 5, Table 6, Table 7, Table 8, and Table 9 for the FE-TX port numbers associated with

the interface processor slots in your chassis. If you install a VIP with two FE-TX port adapters, you

can conﬁgure both ports; if you install a VIP with one FE-TX port adapter, you need conﬁgure only

that port.

Note Table 5, Table 6, Table 7, Table 8, and Table 9 indicate FE-TX interface port numbers based

on the slots in which they can be installed; they do not represent examples of maximum FE-TX

conﬁgurations.

Conﬁguring the FE-TX Port Adapters—Descriptions and Examples

Following are descriptions and examples of the commands for conﬁguring the VIP FE-TX interface

3/0/0 (slot 3, port adapter 0, Fast Ethernet interface port 0). If a second Fast Ethernet interface is

present, conﬁgure it the same way except that the port adapter number is port adapter 1 (3/1/0).

Descriptions are limited to ﬁelds that are relevant for establishing and verifying the conﬁguration.

After conﬁguring the new FE-TX interface, use show commands to display the status of the new

interface or all interfaces, or to verify changes you have made.

Depending on the requirements for your system conﬁguration and the protocols you plan to route on

the interface, you might also need to enter other conﬁguration subcommands. For complete

descriptions of conﬁguration subcommands and the conﬁguration options available for Fast Ethernet

interfaces, refer to the publications listed in the section “If Y o u Need More Information” on page 2.

Ethernet 10BASE-T Overview

The VIP 4E port adapter provides up to four IEEE 802.3 Ethernet 10BASE-T interfaces on the VIP.

Each Ethernet 10BASE-T interface allows a maximum bandwidth of 10-Mbps, for a maximum

aggregate bandwidth of 40 Mbps. All four ports run at line speed.

The term Ethernet is commonly used for all carrier sense multiple access/collision detection

(CSMA/CD) local-area networks (LANs) that generally conform to Ethernet speciﬁcations,

including IEEE 802.3. Ethernet Version 2 and IEEE 802.3 were based on, and developed shortly

after, Ethernet Version 1. The slight differences between Ethernet and IEEE 802.3 are implemented

in hardware, and both are supported automatically by the 4E without any hardware conﬁguration

changes. Together, Ethernet and IEEE 802.3 are the most widely used LAN protocols. They are well

suited to applications where a local communication medium must carry sporadic, occasionally

heavy trafﬁc at high peak data rates.

Stations on a CSMA/CD LAN can access the network at any time. Before sending data, the station

listens to the network to see of it is already in use. If it is, the station waits until the network is not

in use, then transmits. A collision occurs when two stations listen for network trafﬁc, hear none, and

transmit simultaneously. When this happens, both transmissions are damaged, and the stations must

retransmit. The stations detect the collision and use backoff algorithms to determine when they

should retransmit.

VIP Port Adapter Functions

Both Ethernet and IEEE 802.3 are broadcast networks, which means that all stations see all

transmissions. Each station must examine received frames to determine whether it is the intended

destination and, if it is, pass the frame to a higher protocol layer for processing. IEEE 802.3 speciﬁes

several different physical layers, and Ethernet deﬁnes only one. Each IEEE 802.3 physical layer

protocol has a name that summarizes its characteristics in the format speed/signaling

method/segment length where speed is the LAN speed in Mbps, signaling method is the signaling

method used (either Baseband or Broadband), and segment length is the maximum length between

stations in hundreds of meters.

4E Port Adapter Description and 10BASE-T Speciﬁcations

The 4E port adapter is currently only available on the VIP-FE-TX/4E, which has a single Fast

Ethernet (FE-TX) port adapter in port adapter slot 0, and a single Ethernet 10BASE-T (4E) port

adapter in port adapter slot 1. (For a description of the FE-TX port adapter, refer to the section

“FE-TX Port Adapter” on page 29.) Figure 24 shows the VIP-FE-TX/4E.

Note VIP conﬁgurations using only one 4E port adapter and a port adapter blank, or two 4E port

adapters, are currently not supported. The FE-TX and 4E port adapters have a handle attached, but

this handle is not shown to allow a full view of detail on each port adapter’s faceplate.

The Ethernet speciﬁcations call the 4E device a transceiver, and it is connected to the station with a

transceiver cable. The 4E port adapter is not an end station. The IEEE 802.3 speciﬁcations refer to

the same type of device as a media attachment unit (MAU) and to the cable as an attachment unit

interface (AUI). Only transceiver cables can connect to the 4E ports directly.

4E Port Adapter LEDs

The 4E port adapter contains the enabled LED, standard on all port adapters, and a one status LED

for each port. After system initialization, the enabled LED goes on to indicate that the 4E port

adapter has been enabled for operation. (The LEDs are shown in Figure 25.) The following

conditions must be met before the enabled LED goes on:

• The 4E interface is correctly connected to the backplane and receiving power.

• The 4E-equipped VIP contains a valid microcode version that has been downloaded successfully.

• The bus recognizes the 4E-equipped VIP.

If any of these conditions is not met, or if the initialization fails for other reasons, the enabled LED

does not go on.

When an RJ-45 port is active, its link LED is on when the 4E port adapter is receiving a carrier signal

from the network.

4E Port Adapter Receptacles, Cables, and Pinouts

The interface connectors on the 4E port adapter are four individual RJ-45 receptacles. You can use

all four simultaneously. Each connection supports IEEE 802.3 and Ethernet 10BASE-T interfaces

compliant with appropriate standards. The RJ-45 connections require external transceivers.

Figure 26 sho ws the RJ-45 connectors. Table 12 lists the pinouts and signals for the RJ-45

connectors.

Warning The ports labeled “Ethernet,” “10BaseT,” “Token Ring,” “Console,” and “AUX” are

safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV

circuits. Because the BRI circuits are treated like telephone-network voltage, avoid connecting the

SELV circuit to the telephone network voltage (TNV) circuits. (For translated versions of this

Attaching 4E Port Adapter Interface Cables

On a single 4E port adapter, you can use up to four RJ-45 connections.

Note RJ-45 cables are not available from Cisco Systems; they are available from outside

commercial cable vendors.

Connect RJ-45 cables to the 4E port adapter as follows:

Step 1 Attach the Category 5 UTP cable directly to the RJ-45 port on the 4E port adapter. (See

Figure 29.)

The 4E port adapter is an end station device and not a repeater. You must connect the 4E

port adapter to a repeater or hub.

Step 2 Attach the ferrite bead to the RJ-45 cable (at either end), as shown in Figure 30.

Caution The ferrite bead prevents electromagnetic interference (EMI) from affecting the

4E-equipped system and is a required component for proper system operation.

Step 3 Attach the network end of your RJ-45 cable to your 10BASE-T hub or repeater, DTE, or

other external 10BASE-T equipment.

This completes the 4E installation. Proceed to the section “Checking the VIP Installation” on

page 19, then to the section “Conﬁguring the 4E Interf aces,” which follows.

Conﬁguring the 4E Interfaces

If you installed a new 4E port adapter or if you want to change the conﬁguration of an existing

interface, you must enter Conﬁguration mode using the conﬁgure command. If you replaced a 4E

port adapter that was previously conﬁgured, the system will recognize the new 4E interfaces and

bring them up in their existing conﬁguration.

After you verify that the new 4E port adapter is installed correctly (the enabled LED goes on), use

the privileged-level conﬁgure command to conﬁgure the new interfaces. Be prepared with the

information you will need, such as the following:

• Protocols you plan to route on each new interface.

• Internet protocol (IP) addresses if you plan to conﬁgure the interfaces for IP routing.

• Whether the new interfaces will use bridging.

For a summary of the conﬁguration options available and instructions for conﬁguring the 4E

interfaces on the VIP, refer to the Router Products Conﬁguration Guide.

The conﬁgure command requires privileged-level access to the EXEC command interpreter, which

usually requires a password. Contact your system administrator if necessary to obtain EXEC-level

access. The 4E interfaces on a VIP can both be conﬁgured at 10 Mbps, half duplex (HDX) or full

duplex (FDX), for a maximum aggregate bandwidth of 40 Mbps.

VIP Port Adapter Functions

Selecting Chassis Slot, Port Adapter, and Ethernet 10BASE-T Interface Port Numbers

The following section describes how to identify chassis slot, port adapter, and Ethernet 10BASE-T

interface port numbers.

Note Although the processor slots in the seven-slot Cisco 7000 and 13-slot Cisco 7513 are

vertically oriented and those in the ﬁve-slot Cisco 7010 and Cisco 7505 are horizontally oriented, all

models use the same method for slot and port numbering. (Refer to Figure 2, Figure 3, Figure 4,

Figure 5, or Figure 6 for interface processor slot orientation in your chassis.)

In the router, physical port addresses specify the actual physical location of each interface port on

the router interface processor end. (See Figure 22.) This address is composed of a three-part number

in the format chassis slot number/port adapter number/interface port number.

The ﬁrst number identiﬁes the chassis slot in which the VIP is installed (as shown in the example

system in Figure 31). The second number identiﬁes the physical port adapter number on the VIP, and

is either 0 or 1. The interface ports on each 4E port adapter are always numbered in sequence as

interface 0 through 3.

Interface ports on the VIP maintain the same address regardless of whether other interface

processors are installed or removed. However, when you move a VIP to a different slot, the ﬁrst

number in the address changes to reﬂect the new slot number.

VIP Port Adapter Functions

Figure 22 shows some of the slot port adapter and interface ports of a sample Cisco 7505 system.

For example, on a FE-TX/4E VIP in slot 3, the address of the ﬁrst Fast Ethernet port adapter is 3/0/0

(chassis slot 3, port adapter slot 0, and interface port 0—see the section “Selecting Chassis Slot, Port

Adapter, and Fast Ethernet Interface Port Numbers” on page 38 for the Fast Ethernet numbering

scheme), and the addresses for the Ethernet 10BASE-T interface ports on the second port adapter

(which is a 4E) are 3/1/0 through 3/1/3 (chassis slot 3, port adapter slot 1, and interface ports 0

through 3).

The ﬁrst port adapter slot number is always 0. The second port adapter slot number is always 1. The

individual interface port numbers always begin with 0. The number of additional ports depends on

the number of ports on a port adapter. For example, the four 10BaseT interface ports on a 4E port

adapter in the second port adapter slot in chassis slot 3, would have the following addresses: 3/1/0,

3/1/1, 3/1/2, and 3/1/3. (See Figure 31.)

Note If you remove the 4E-equipped VIP from slot 3 and install it in slot 2, the addresses of those

same 10BASE-T ports become 2/1/0 through 2/1/3.

Note VIP conﬁgurations using only one 4E port adapter, and a port adapter blank, or two 4E port

adapters, are currently not supported.

You can identify interface ports by physically checking the slot/port adapter/interface port location

on the back of the router or by using software commands to display information about a speciﬁc

interface or all interfaces in the router.

To display information about a speciﬁc interface, use the show interfaces command with the

interface type and port address in the format show interfaces [type slot/port adapter/port].

VIP Port Adapter Functions

Following is an example of how the show interfaces [type slot/port adapter/port] command displays

status information (including the physical slot and port address) for the interfaces you specify. In

these examples, most of the status information for each interface is omitted, and the four Ethernet

10BASE-T interfaces (0–3) are in chassis slot 3, in port adapter slot 1. (Interfaces are

administratively shut down until you enable them.)

Ethernet 10BASE-T interface port adapters are always numbered as port adapter 1 because VIPs

currently support only one 4E port adapter with the FE-TX/4E conﬁguration, and the 4E port adapter

is always in the second port adapter slot location (port adapter slot 1). With this VIP conﬁguration,

a FE-TX port adapter is always in port adapter slot 0.

Note Refer to the section “Selecting Chassis Slot, Port Adapter, and Fast Ethernet Interface Port

Numbers,” on page 38, for your FE-TX interface.

SELV Circuit Warning Translations

Warning The ports labeled “Ethernet,” “10BaseT,” “Token Ring,” “Console,” and “AUX” are

safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV

circuits. Because the BRI circuits are treated like telephone-network voltage, avoid connecting the

SELV circuit to the telephone network voltage (TNV) circuits.

Waarschuwing De poorten die "Ethernet", "10BaseT", "Token Ring", "Console" en "AUX" zijn

gelabeld, zijn veiligheidscircuits met extra lage spanning (genaamd SELV = Safety Extra-Low

Voltage). SELV-circuits mogen alleen met andere SELV-circuits verbonden worden. Omdat de

BRI-circuits op dezelfde manier als telefoonnetwerkspanning behandeld worden, mag u het

SELV-circuit niet verbinden met de telefoonnetwerkspanning (TNV) circuits.

Varoitus Portit, joissa on nimet "Ethernet", "10BaseT", "Token Ring", "Console" ja "AUX", ovat

erityisen pienen jännityksen omaavia turvallisuuspiirejä (SELV-piirejä). Tällaiset SELV-piirit tulee

yhdistää ainoastaan muihin SELV-piireihin. Koska perusluokan liitäntöjen (Basic Rate Interface- eli

BRI-liitännät) jännite vastaa puhelinverkoston jännitettä, vältä SELV-piirin yhdistämistä

puhelinverkoston jännitepiireihin (TNV-piireihin).

Attention Les ports étiquetés « Ethernet », « 10BaseT », «okTen Ring », « Console » et «UAX » sont

des circuits de sécurité basse tension (Safety Extra-Low Voltage ou SELV). Les circuits SELV ne

doivent être interconnectés qu'avec d'autres circuits SELV. Comme les circuits BRI sont considérés

comme des sources de tension de réseau téléphonique, éviter de connecter un circuit SELV à un

circuit de tension de réseau téléphonique (telephone network voltage ou TNV).

Warnung Die mit "Ethernet", "10BaseT", "Token Ring", "Console" und "AUX" beschrifteten

Buchsen sind Sicherheitskreise mit Sicherheitskleinspannung (Safety Extra-Low Voltage, SELV).

SELV-Kreise sollten ausschließlich an andere SELV-Kreise angeschlossen werden. Da die

BRI-Kreise wie Telefonnetzspannungen behandelt werden, ist der SELV-Kreis nicht an

Telefonnetzspannungskreise (TNV) anzuschließen.

Avvertenza Le porte contrassegnate da "Ethernet", "10BaseT", "TokenRing", "Console" e "AUX"

sono circuiti di sicurezza con tensione molto bassa (SELV). I circuiti SELV devono essere collegati

solo ad altri circuiti SELV. Dato che i circuiti BRI vengono trattati come tensioni di rete telefonica,

evitare di collegare il circuito SELV ai circuiti in cui è presente le tensione di rete telefonica (TNV).

Advarsel Utgangene merket "Ethernet", "10BaseT", "Token Ring", "Console" og "AUX" er

lavspentkretser (SELV) for ekstra sikkerhet. SELV-kretser skal kun kobles til andre SELV-kretser.

Fordi BRI-kretsene håndteres som telenettspenning, unngå å koble SELV-kretsen til kretser for

telenettspenning (TNV).

Aviso As portas "Ethernet", "10BaseT", "Token Ring", "Console", and "AUX" são circuitos de

segurança de baixa tensão (SELV). Estes circuitos deverão ser apenas ligados a outros circuitos

SELV. Devido ao facto de os circuitos BRI (Interface de Ritmo Básico) serem tratados como sendo

de tensão equivalente à da rede telefónica, evite ligar o circuito SELV aos circuitos TNV (tensão de

rede telefónica).

¡Advertencia! Los puertos "Ethernet", "10BaseT", "Token Ring", "Console" y "AUX" son

circuitos de muy baja señal que garantizan ausencia de peligro (Safety Extra-Low Voltage = SELV).

Estos circuitos SELV deben ser conectados exclusivamente con otros también de tipo SELV. Puesto

que los circuitos tipo BRI se comportan como aquéllos con voltajes de red telefónica, debe evitarse

conectar circuitos SELV con circuitos de voltaje de red telefónica (TNV).

Varning! De portar som är märkta "Ethernet", "10BaseT", "Token Ring", "Console" och "AUX" är

SELV-kretsar, d.v.s. skyddskretsar med extra låg spänning (SELV: Safety Extra-Low Voltage =

skyddsklenspänning). SELV-kretsar får endast anslutas till andra SELV-kretsar. Eftersom

BRI-kretsar behandlas liksom telefonnätsspänning bör SELV-kretsen inte anslutas till

telefonnätsspänningskretsar (TNV-kretsar).

Cisco Information Online

Cisco Information Online (CIO) is Cisco Systems’ primary, real-time support channel. Maintenance

customers and partners can self-register on CIO to obtain additional content and services.

Available 24 hours a day, 7 days a week, CIO provides a wealth of standard and value-added services

to Cisco’s customers and business partners. CIO services include product information, software

updates, release notes, technical tips, the Bug Navigator, conﬁguration notes, brochures,

descriptions of service offerings, and download access to public and authorized ﬁles.

CIO serves a wide variety of users through two interfaces that are updated and enhanced

simultaneously—a character-based version and a multimedia version that resides on the World Wide

Web (WWW). The character-based CIO (called “CIO Classic”) supports Zmodem, Kermit,

Xmodem, FTP, Internet e-mail, and fax download options, and is excellent for quick access to

information over lower bandwidths. The WWW version of CIO provides richly formatted

documents with photographs, ﬁgures, graphics, and video, as well as hyperlinks to related

information.

You can access CIO in the following ways:

• WWW: http://www.cisco.com

• Telnet: cio.cisco.com

• Modem: From North America, 408 526-8070; from Europe, 33 1 64 46 40 82. Use the

following terminal settings: VT100 emulation; data bits: 8; parity: none; stop bits: 1; and baud

rates up to 14.4 kbps.
