Connecting a device to the  
RJ-45 ports  
To connect a workstation compatible with IEEE 802.3 (Ethernet Ver-  
sion 1.0 and 2.0) or a fast access device (such as a server) to the  
switch’s RJ-45 ports using UTP cable (Category 5):  
1
Make sure that the device has a 100Mbps (100Base-FX or 10/  
100Base-TX) network interface card installed.  
If not, use your network interface card’s documentation to  
install and configure it correctly.  
2
3
If your workstation is fitted with an RJ-45 interface then there is  
no problem. However, it is possible to attach to other connector  
types using an appropriate adapter. For example, use a UTP/  
10Base-FL adapter for fiber connections  
Connect one end of the UTP cable to an RJ-45 port on the  
switch.  
According to IEEE 802.3, the cable length must not exceed 100  
meters (approximately 325 feet).  
4
Connect the other end to the 100Base-TX connection on the  
device.  
Connecting the  
management PC  
To manage the switch from a PC connected directly to the switch, the  
PC must not use frame tagging. To manage the switch from a PC with  
IEEE 802.1Q tagged frames, management must be through a device  
which untags the frames.  
Cable for the Console Port  
If you connect a PC (via the Console Port), then use a null-modem ca-  
ble.

Intel Express 520T Switch  
Connecting the Power  
Introduction  
After connecting the devices to the switch, connect the power cable.  
There are certain practical and safety considerations to be made be-  
fore powering the switch on.  
The Power Cable  
Ground warning  
The switch is delivered with a power cable that fits the power sockets  
in your country. If this is not the case, contact your dealer immediate-  
ly and ask for the correct power cable.  
Power cable wiring color  
code  
The wires in the power cable provided are color coded:  
Color  
Connection  
Ground  
Neutral  
Live  
Green and yellow  
Blue  
Brown  
Important for UK use  
If the colors of the wires in the power cable provided do not corre-  
spond with the markings that identify the terminals in your plug:  
1
Make sure that the green and yellow wire is connected to the  
terminal marked with the letter E, or with the ground symbol  
, or is colored green and yellow.  
2
3
Make sure that the blue wire is connected to the terminal  
marked with the letter N or colored black.  
Make sure that the brown wire is connected to the terminal  
marked with the letter L or colored red.  
Power supply to a rack  
If the switch is installed in a rack, make sure the rack’s power supply  
socket has a ground connection and the rack is connected to a branch  
supply or a power supply socket with a ground connection.  
To avoid overloading the circuit and damaging the wiring of the pow-  
er supply, the power supply to the rack must be adequate to cover the  
extra power consumed by the switch.

Power up  
Powering up the switch  
Follow these steps to power up the switch:  
1
Push the female end of the power cable into the main socket (in  
the rear panel); plug the other end into the power supply outlet.  
2
Make sure that the Power LED (on the front panel) is green.  
If it isn’t green, make sure that the power outlet is working cor-  
rectly (switched on). If the power outlet is on and the Power  
LED is not green, then there is a fault within the switch and  
you must contact your dealer.  
3
Verify that an LED is lit for each of the front panel ports where  
a powered on device is connected.  
Start-up procedure  
Immediately after power-up, the following should happen during  
start-up:  
Stage STATUS LED...  
Then the switch...

If the Status LED remains red, then the switch has not started success-  
fully. Try to restart it; if the switch does not start, contact your dealer.  
Look at the other front panel LEDs during start-up and check that  
they are operating correctly.  
Port LED states  
The LEDs reflect the state of each port:

Default settings after start-  
up  
Once the switch has started successfully, installation is complete and  
the switch is using its default setting (also known as default configu-  
ration):  
•
•
•
•
All ports are enabled.  
All ports operate in auto-negotiation mode.  
Spanning Tree is disabled on all ports.  
Addresses that have been silent for more than 15 minutes are  
purged from the switch’s address table (the MAC Address Aging  
time).  
•
•
•
No access restrictions to Local Management (Telnet).  
No SNMP restrictions.  
No permanent MAC address entries defined. A permanent entry  
is a MAC address that is defined as being permitted only on a  
certain port. This can be a useful security feature.  
•
All ports are in the same VLAN (named <System>) and VLAN  
mode (Stand-alone mode). VLANs allow you to create virtual  
networks using specific switch ports, IP addresses, IP subnets  
and MAC addresses.  
•
•
Flow Control is enabled on all ports.  
The connection with Local Management is timed-out after 10  
minutes if there has been no input during this period.  
After start-up  
This default configuration is adequate for simple workgroup environ-  
ments to operate in basic switching mode.  
Although the switch continues to operate without problems, we rec-  
ommend that you change certain parameters to suit your own require-  
ments.

Intel Device View  
After a Switch or Stack is Contacted  
Commands  
When Intel Device View contacts a switch, the basic commands are  
supplemented with:  
•
Local Management access — provides Telnet access to monitor-  
ing functions embedded in the switch.  
•
RMON facility — gathers information about the network traffic,  
monitors traffic on subnets and enables you to define alarms on  
the individual ports.  
•
Stack Synchronization Manager (for stacks only) — enables you  
to establish a stack from a group of switches connected via a  
Matrix Module, or add a switch to an existing stack and then syn-  
chronize their configurations.  
•
•
Switch Position Organizer (for stacks only) — enables you to  
move the switches displayed on screen around in the stack.  
Color Code Matrix Ports (for stacks only) — colors the individ-  
ual ports on the Matrix Module. This simplifies the task of trac-  
ing cables, as the ports on the Stack Interface Modules become  
the same color as the corresponding Matrix Module port.

Installing and Managing  
Switches  
Following installation of  
Intel Device View  
After installing Intel Device View, you can add new switches, estab-  
lish or expand stacks of switches, and manage existing switches and  
stacks.  
Adding new switches  
The Install Wizard  
To add new switches (that have not been assigned an IP address) to  
Intel Device View, select Device>Install. The Install Wizard  
will start and guide you through the installation.  
The Install Wizard requires that you enter a minimum amount of in-  
formation to set up the switch for management by Intel Device View.  
To select the correct new device, you need to know the device’s MAC  
address. You can find this on a label on the rear panel of the device.  
You must assign an IP address (and subnet mask) to the switch on  
your Local Area Network (LAN).  
Intel Device View uses this address for configuration and manage-  
ment purposes.

Matrix Module connected  
to a new switch  
When the Install wizard detects that a new switch is connected to a  
Matrix Module, a message informs that you must decide how to man-  
age the switch.  
If you want to manage it separately, the installation is completed and  
the switch is displayed in the Intel Device View window. If you want  
to manage it as part of a stack, you have the opportunity to assign con-  
secutive IP addresses in the next dialog.  
The Synchronization Wizard completes the installation. The com-  
plete stack, including the new switch, then appears in the Intel Device  
View window. The Synchronization wizard is described in detail in  
“Stack Synchronization Manager”, p. 95.

VLAN  
The diagram above, shows two switches. On the left, we see the two  
switches connected and the ports are grouped in two VLANs: A and  
B. On the right, we have enabled STP; STP blocks the path between  
X and Z (to avoid looping) and, therefore, destroys the VLAN setup  
(because VLAN B needs these ports to receive messages).  
Why change these from  
their defaults?  
The switch is delivered with Spanning Tree default values set to those  
recommended by the IEEE 802.1d standard. These values are conser-  
vative worst-case estimates for LANs consisting of a large number of  
switches. Therefore, changing these default values may improve the  
performance of your network.

In this chapter  
In this chapter you will learn how to use Advanced Configuration ef-  
fectively. This chapter covers the Virtual LAN (VLAN) features.  
You can create logical network groups (VLANs) by segmenting the  
switch; for example, according to the subnetting scheme within your  
network. Each VLAN is an isolated group and the switch only for-  
wards traffic between members of the same group. Communication  
between groups can be implemented using routers.  
Note This switch is able to forward tagged frames from devices  
supporting IEEE 802.1p/Q. These frames are only for-  
warded to ports that are in the same VLAN.  
However, IP policies cannot be used for devices using tagged VLANs  
and IP learning is not possible.  
VLANs (Virtual LANs)  
Purpose  
You can use VLANs to:  
•
•
•
Create up to 128 separate user groups  
Limit broadcast and multicast traffic  
Increase security by limiting communication between groups

For a more comprehensive explanation of the VLAN concept, refer  
to the online help.  
Warning when using STP  
It is important to be aware of problems that may arise when using  
Spanning Tree and VLANs. The Spanning Tree can use alternative  
paths (such as different ports) to get messages to their destination.  
VLANs specify which ports can receive messages (see “Spanning  
Tree”, p. 55).  
Warning When using the Spanning Tree facility, use only one  
VLAN. If you use two or more VLANs, unexpected  
changes in your network topology may occur.  
Policy-based VLANs  
Policy hierarchy  
The switch or stack uses “Policy-based VLANs”. This means that the  
devices attached to the switch/stack can be grouped by any combina-  
tion of MAC address, IP address, IP net and port number; therefore,  
devices can belong to one or more VLANs.  
To avoid conflicts between two VLANs, a strict priority of the poli-  
cies is used:  
1. MAC address  
2. IP address and IP net  
3. Port  
Warning This means that a station learned by a MAC rule is not  
learned by an IP or Port rule, and a station learned by an  
IP rule is not learned by a Port rule. Only stations that  
are not learned by MAC or IP rules are learned by a  
Port rule.  
Note IP policies can be used only when IP learning is enabled on  
the respective ports.

VLAN Mode  
Description  
Stand-alone  
For single switches: there is no exchange of  
information with VLANs on other switches;  
each switch is its own domain  
(STDALONE).  
For switches in a stack: there is an exchange  
of information using VLANs between the  
switches in the stack; these switches are in  
their own domain (STDALONE).  
Distributed  
A domain is a collection of switches and  
can contain up to 128 VLANs. If you select  
distributed, each switch will be able to com-  
municate with all the others in this domain.

IGMP pruning  
Warning when using  
pruning  
It is important to be aware of problems that may arise when using  
IGMP pruning and IP Multicast addresses.  
Warning When using the IGMP pruning, IP multicast packets not  
based on IGMP are discarded.  
IGMP pruning can only be used in VLANs that have an IP link. En-  
abling IGMP pruning stops Layer 2 forwarding of IP multicast pack-  
ets in all other VLANs without IP links.  
Only enable IGMP pruning (on this device) when it is connected be-  
tween the device receiving the packets and an IP multicast routing de-  
vice. Or, disable IGMP pruning (on this device) when it is connected  
between the device transmitting the packets and an IP multicast rout-  
ing device.

Console Port Use and Troubleshooting  
Use of the Console Port  
Purpose of Console Port  
Local Management  
If you lose contact with the switch and the Recovery Manager in Intel  
Device View or Local Management over the LAN cannot contact it,  
then the following is possible via the Console port on the front of the  
switch.  
During normal operation (the switch is running and the Status LED is  
green) the Console port will give access to a menu, identical to the  
one accessible via a telnet connection to the switch. The menu allows  
configuration of basic parameters, extensive monitoring, flash opera-  
tions, reset of the switch etc.  
Maintenance Mode  
If the switch is failing for some reason (System LED goes red), and  
cannot start correctly after a reset, this may be caused by either hard-  
ware failure, corruption of the software, or corruption of the switch  
configuration. To allow recovery from such a situation when the Re-  
covery Manager of Intel Device View cannot be applied, the mainte-  
nance mode is provided. In the following, various problems are  
described as well as the way they are solved using maintenance mode.  
In the next section it is explained how to start and use the maintenance  
mode.  
Note Loading software to the switch in Maintenance Mode  
should only be done as a last resort, the reason being that  
the software and configuration are already resident in the  
flash memory is overwritten and lost.  
Switch Software  
The software for the switch (including a default configuration) re-  
sides in the switch’s flash memory. A backup of the software is pro-  
vided on the CD delivered with the switch, and the newest software  
versions may be downloaded via the Internet. The software files may  
be used for restoring or upgrading the switch software.  
Restoring Software  
The switch software may be restored/downloaded from a TFTP serv-  
er, if the current software in flash memory has been corrupted. The  
TFTP and BOOTP commands may both be used to accomplish this.  
For the TFTP command an external TFTP server with the software  
must be present on the network. For the BOOTP command a BOOTP/  
TFTP server (also often referred to as a boot server) must be present.

Console Port Use and Troubleshooting  
Upgrading Software  
Switch Configuration  
If a working switch software needs to be upgraded, it is recommended  
to use the Software Upgrade Wizard in Intel Device View rather than  
the maintenance mode commands. This is easier and the existing con-  
figuration is retained.  
The configuration information for the switch is stored in two files re-  
siding in flash memory. The two files are named after the MAC ad-  
dress of the switch. One of them, inxxxxxx.p, contains all the basic  
configuration parameters, while the other, STDALONE.nvp, con-  
tains the VLAN policy database.  
Backing up the  
Configuration  
The two configuration files may be backed up using a TFTP client on  
an external machine (e.g. MS Windows*, Unix* or other). Please fol-  
low the documentation for the TFTP client application for further in-  
structions. However, it is recommended to use Intel Device View for  
doing backup of the configurations.  
Restoring the  
Configuration  
The two configuration files may be restored using a TFTP client on  
an external machine (e.g. MS Windows*, Unix* or other), if the  
switch configuration has been lost or corrupted. It is recommended to  
use Intel Device View for restoring the configurations rather than  
manual TFTP.  
Reset to Factory Defaults  
If the configuration in the switch has been corrupted in such a way  
that the switch is not able to start properly after reset (System LED  
goes red), it may be necessary to reset the switch configuration to fac-  
tory defaults. The RUN Defparm command may be used to do this.  
Please note, that this will discard the existing configuration in the  
switch. This method may also be used, if the configuration by mistake  
has made it impossible to contact the switch by other means. It is also  
the only way to regain access to the switch, if the administrator pass-  
word has been lost.

server contains a bootptab file with an entry for the switch which  
is defined by the MAC address.  
2. If a boot server which holds the software for the switch receives  
the boot request, it loads the boot software over the network to  
the destination MAC address.

Using Maintenance Mode  
Purpose  
Maintenance Mode offers three facilities:  
•
It allows you to force the switch to load a specified software file  
from any specified TFTP server.  
•
It provides an emergency facility to force boot the switch from a  
specified boot server if the switch cannot boot from Flash Mem-  
ory. From Maintenance Mode the switch is forced to issue a

Console Port Use and Troubleshooting  
BOOTP request and the name of the boot software to a specified  
boot server. This is useful if the boot server being used does not  
support the use of a bootptab file.  
•
It runs tests on hardware and provides diagnostic information.  
Note Loading software to the switch in Maintenance Mode  
should only be done as a last resort. This is because the soft-  
ware and configuration already resident in the flash memory  
is overwritten and lost.  
Important considerations  
Consider these points when using Maintenance Mode:  
•
•
•
The switch is not operational and the expansion board ports can-  
not be used.  
Only simple command-line access is possible via the Console  
port.  
There is a delay before you see the command prompt; this is due  
to a hardware test routine being completed.  
To enter Maintenance  
Mode  
To enter Maintenance Mode:  
1
Using a pointed tool — such as a bent paper clip, press the  
Resetbutton on the front of the switch and hold it until the  
SYSTEMLED flashes green quickly (five times per second).  
2
3
Release the Resetbutton.  
Attach a VT100-compatible terminal to the serial port on the  
front panel using the cable supplied.  
4
To display the command prompt on screen, press the Enter key  
a couple of times.

Console Port Use and Troubleshooting  
Troubleshooting Tools  
Troubleshooting tools  
available  
The tools available for troubleshooting on the switch are:  
The LED indicators  
These are located on the front panel of the switch. The LEDs indicate  
the overall switch status, and the status of each of the switch’s ports  
and backplane segments (where applicable). See earlier in this man-  
ual for a full description of the LEDs and their use.  
SNMP  
SNMP management in the switch is based on standard Management  
Information Base (MIB) II and Private Enterprise MIB extensions.  
You can configure the switch to send SNMP Traps to defined loca-  
tions, thus allowing the possibility of performing limited trouble-  
shooting from an SNMP Management Center.  
Intel Device View  
Intel Device View offers several features that can help your trouble-  
shooting. These include: diagnostic messages, a log of system events,  
a log of errors and a list of SNMP traps.  
Troubleshooting Procedure  
Isolating the Problem  
To isolate the problem  
If the switch has a problem, use the following procedure to isolate the  
problem:  
1
2
Check the LEDs.  
The LEDs provide instant visual indication of the status of the  
switch and the status of each ports.  
Check the Diagnosticswindow.  
The diagnostics tool automatically detects possible problems  
and indicates possible causes and solutions. Use of this tool is  
described in “Diagnostics Window”, p. 37.

Check for any relevant messages in the Trapwindow.  
Use of this tool is described in “Trap Window”, p. 38.  
Check for any relevant messages in the Systemwindow.  
The System Log gives details about system events that occur  
during start-up and operation and also the general state of the  
switch. Typical information recorded in the System Log  
includes all major events during start-up, system changes,  
unexpected events and configuration errors. The System Log  
reports such things as software successfully located and loaded,  
ports enabled or disabled, and if any SNMP traps have been  
sent. Use of this tool is described in “System Window”, p. 39  
5
6
Check for any relevant messages in the Errorswindow.  
Use of this tool is described in “Errors Window”, p. 39.  
Check the fault counters on the switch ports and watch for any  
significant error counters.  
Further Evaluation of the Problem  
If the problem is still not  
isolated  
If you still cannot resolve the problem after following the procedures  
above, access the Monitoring menu within Local Management. Mon-  
itoring is a valuable tool for the troubleshooting process and offers  
extensive information on the performance and the status of the switch  
hardware and software, the switch ports and the traffic patterns on  
each port.  
The general facilities available within the Monitoring menu are de-  
scribed in the following subsections. The use of these facilities de-  
pends on the problem and on any relevant information collected in the  
previous procedure.  
Typical Problems and Causes  
Typical problems that  
could be encountered  
This section gives some examples of typical problems that could be  
encountered during the installation and configuration of the switch,  
and their possible cause. Configuration problems, defective cables  
and problems with communication among devices are the most com-  
mon switch malfunctions.

Start-up Problems  
I’ve forgotten my password  
Explanation: You are prompted for a password on the Login  
screen.  
Action: Enter Maintenance Mode, and type: run defparm.  
Consequence: This resets the configuration to the default values so  
you can assign a new password.  
When I make changes to the switch’s configuration, they take effect but as soon as the  
switch is powered off and on again the changes are lost  
Explanation: When you change the switch’s configuration, you are  
changing the current active configuration that is running in RAM.  
However, every time the switch starts up it loads the configuration  
that is stored in its flash memory. Therefore, if you make a change  
to the configuration and want to keep it, you need to save the new  
configuration to the switch’s flash memory.  
Action: Save the configuration changes to flash memory.  
To check the status of the configuration, select Configura-  
tion>Software.  
Performance Problems  
One or more workstations cannot communicate with a server or other device through  
the switch  
Explanation: This symptom might be noticed on one or more seg-  
ments connected to the switch, and could be caused by cable faults,  
inappropriate configuration or faulty installation.  
Action: Check all connections and verify your configuration.  
Check any error counters for the ports.  
The 100Mbps ports are not working, or work very poorly  
Explanation: This is probably due to incorrect configuration of the  
auto-negotiation duplex settings and link speeds.  
Action: Check the negotiated settings in the switch and compare  
them to the expected values.

Console Port Use and Troubleshooting  
I have poor performance and high numbers of second port drops  
Explanation: There may be a loop in the network and Spanning  
Tree is not enabled.  
Action: Avoid loops, or alternatively, either enable STP on all the  
ports (using Device Setup) or specific ports (using Port  
Setup).  
Communication Problems  
The most common  
problems are cable  
problems  
A high percentage of faults are caused by cable faults such as loose  
connections or inappropriately wired cables.  
Management PCs using  
IEEE 802.1Q tagged  
frames  
A management PC using IEEE 802.1Q tagged frames may experi-  
ence communication difficulties with the switch. To manage the  
switch from a PC connected directly to the switch, the PC must not  
use frame tagging. To manage the switch from a PC with IEEE  
802.1Q tagged frames, management must be through a device which  
untags the frames.  
Spanning Tree topology  
changes  
When a change is detected in the Spanning Tree network, the devices  
forming the Spanning Tree go into a learning state to determine the  
optimal routes between network segments. During this learning state,  
the switch will not forward data traffic.  
This is a normal occurrence for Spanning tree devices and no reme-  
dial action is required. However, if the switch goes into the learning  
state too frequently, the Spanning Tree may be unstable and should  
be examined and possibly reconfigured.  
To troubleshoot  
communications problems  
If the POWERLED and the STATUSLED are both on, but one or more  
of the port STATUSLEDs are off, then:  
1
2
Reset the switch using the Resetbutton.  
Check the STATUSLED for each switch port to which a cable is  
attached.  
VLANs  
The use of VLAN policies can lead to unexpected communication  
problems. If the policies are not designed with care, ports are not able  
to reach network services. Check your VLAN policies and use the  
VLAN monitoring to review the VLAN membership for that port or  
address.
