Industry Canada Notice CS-03
The Industry Canada label identifies certified equipment. This certification means that the equipment
meets certain telecommunications network protective, operation and safety requirements as
prescribed in the appropriate Terminal Equipment Technical Requirements document(s). The
Department does not guarantee the equipment will operate to the user's satisfaction. Before
installing this equipment, users should ensure that it is permissible to be connected to the facilities of
the local telecommunications company. The equipment must also be installed using and acceptable
method of connection. The customer should be aware that compliance with the above conditions
may not prevent degradation of service in some situations.
Repairs to certified equipment should be coordinated by a representative designated by the supplier.
Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give
the telecommunications company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the power
utility, telephone lines and internal metallic water pipe system, if present, are connected together.
This precaution may be particularly important in rural areas.
Caution: Users should not attempt to make such connections themselves, but should contact the
appropriate electric inspection authority, or electrician, as appropriate.
Notice: The Ringer Equivalence Number (REN) assigned to each terminal device provides an
indication of the maximum number of terminals allowed to be connected to a telephone interface.
The termination on an interface may consist of any combination of devices subject only to the
requirement that the sum of the Ringer Equivalence Numbers of all the devices does not exceed 5.
Avis CS-03 d’Industrie Canada
L’étiquette du ministère des Communications du Canada indique que l’appareillage est certifié,
c’est-à-dire qu’il respecte certaines exigences de sécurité et de fonctionnement visant les réseaux
de télécommunications. Le ministère ne garantit pas que l’appareillage fonctionnera à la satisfaction
de l’utilisateur. Avant d’installer l’appareillage, s’assurer qu’il peut être branché aux installations du
service de télécommunications local. L’appareillage doit aussi être raccordé selon des méthodes
acceptées. Le client doit toutefois prendre note qu’une telle installation n’assure pas un service
parfait en tout temps.
Les réparations de l’appareillage certifié devraient être confiées à un service d’entretien canadien
désigné par lefournisseur. En cas de réparation ou de modification effectuées par l’utilisateur ou de
mauvais fonctionnement del’appareillage, le service de télécommunications peut demander le
débranchment de l’appareillage.
Pour leur propre sécurité, les utilisateurs devraient s’assurer que les mises à la terre des lignes de
distribution d’électricité, des lignes téléphoniques et de la tuyauterie métallique interne sont
raccordées ensemble. Cette mesure de sécurité est particulièrement importante en milieu rural.
Attention: Les utilisateurs ne doivent pas procéder à ces raccordements eux-mêmes mais doivent
plutôt faire appel aux pouvoirs de réglementation en cause ou à un électricien, selon le cas.
Avis: Veuillez prendre note que pour tout appareillage supportant des lignes de type “loopstart,”
l'indice d'équivalence de la sonnerie (IES) assigné à chaque dispositif terminal indique le nombre
maximal de terminaux qui peuvent être raccordés à une interface. La terminaison d'une interface
téléphonique peut consister en une combinaison de quelques dispositifs, à la seule condition que la
somme d'indices d'équivalence de la sonnerie de tous les dispositifs n'excède pas 5. Le REN figure
sur l’étiquette “FCC Rules Part 68” située sur le support du module ou à l’arrière de l’unité.

D.O.C. Explanatory Notes: Equipment Attachment Limitations
The Canadian Department of Communications label identifies certified equipment. This certification
meets certain telecommunication network protective, operational and safety requirements. The
department does not guarantee the equipment will operate to the users satisfaction.
Before installing the equipment, users should ensure that it is permissible to be connected to the
facilities of the local telecommunications company. The equipment must also be installed using an
acceptable method of connection. In some cases, the company’s inside wiring associated with a
single line individual service may be extended by means of a certified connector assembly
(telephone extension cord). The customer should be aware that compliance with the above condition
may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility
designated by the supplier. Any repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications company cause to request the user to
disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the power
utility, telephone lines and internal metallic water pipe system, if present, are connected together.
This precaution may be particularly important in rural areas.
Caution: Users should not attempt to make such connections themselves, but should contact the
appropriate electrical inspection authority, or electrician, as appropriate.

EXCEPT FOR THE WARRANTIES SET FORTH ABOVE, THE SOFTWARE IS LICENSED “AS IS,”
AND JUNIPER NETWORKS DISCLAIMS ANY AND ALL OTHER REPRESENTATIONS,
CONDITIONS, AND WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY,
INCLUDING, WITHOUT LIMITATION, ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE OR ANY WARRANTIES FOR NONINFRINGEMENT OR
ARISING FROM A COURSE OF DEALING, USAGE, OR TRADE PRACTICE. ANY AND ALL SUCH
WARRANTIES ARE HEREBY EXCLUDED TO THE EXTENT ALLOWED BY APPLICABLE LAW.
JUNIPER NETWORKS' SUPPLIERS AND LICENSORS DO NOT MAKE OR PASS ON TO YOU OR
ANY THIRD PARTY ANY EXPRESS, IMPLIED, OR STATUTORY WARRANTY OR
REPRESENTATION, INCLUDING, BUT NOT LIMITED TO, IMPLIED WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR ANY WARRANTIES FOR
NONINFRINGEMENT.
6. Proprietary Rights Indemnification. Juniper Networks shall at its expense defend you against
and, subject to the limitations set forth elsewhere herein, pay all costs and damages made in

States trade secret, provided that you: (a) provide prompt written notice of any such claim, (b) allow
Juniper Networks to direct the defense and settlement of the claim, and (c) provide Juniper Networks
with the authority, information, and assistance that Juniper Networks reasonably deems necessary
for the defense and settlement of the claim. You shall not consent to any judgment or decree or do
any other act in compromise of any such claim without first obtaining Juniper Networks’ written
consent. In any action based on such a claim, Juniper Networks may, at its sole option, either: (1)
obtain for you the right to continue using the Program, (2) replace or modify the Program to avoid the
claim, or (3) if neither (1) nor (2) can reasonably be effected by Juniper Networks, terminate the
license granted hereunder and give you a pro rata refund of the license fee paid for such Program,
calculated on the basis of straight-line depreciation over a five-year useful life. Notwithstanding the
preceding sentence, Juniper Networks will have no liability for any infringement or misappropriation
claim of any kind if such claim is based on: (i) the use of other than the current unaltered release of
the Program and Juniper Networks has provided or offers to provide such release to you for its then
current license fee, or (ii) use or combination of the Program with programs or data not supplied or
approved by Juniper Networks if such use or combination caused the claim.
7. Limitation of Liability. IN NO EVENT WILL JUNIPER NETWORKS OR ITS SUPPLIERS OR
LICENSORS BE LIABLE FOR ANY COST FOR SUBSTITUTE PROCUREMENT; SPECIAL,
INDIRECT, INCIDENTAL, PUNITIVE, EXEMPLARY, OR CONSEQUENTIAL DAMAGES; OR ANY
DAMAGES RESULTING FROM INACCURATE OR LOST DATA OR LOSS OF USE OR PROFITS
ARISING OUT OF OR IN CONNECTION WITH THE PERFORMANCE OF THE SOFTWARE, EVEN
IF JUNIPER NETWORKS HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.
Juniper Networks' cumulative liability to you or any other party for any loss or damages resulting from
any claims, demands, or actions arising out of or relating to this License Agreement shall not exceed
the total fees paid to Juniper Networks for the Software.

users acquire the Software with only the rights set forth in this License Agreement.
10. General: This License shall be governed by and construed in accordance with the laws of the
Commonwealth of Massachusetts, United States of America, as if performed wholly within the state
and without giving effect to the principles of conflict of law. Any dispute arising out of this Agreement
shall be referred to an arbitration proceeding in Boston, Massachusetts, in accordance with the

arbitrator shall not be permitted to award punitive or indirect damages. The arbitrator's decision and
award shall be final and binding and may be entered in any court having jurisdiction. The terms of
this section shall not prevent any party from seeking injunctive relief in any court of competent
jurisdiction in order to protect its proprietary and confidential information. If any term or provision
hereof is found to be void or unenforceable by a court of competent jurisdiction, the remaining
provisions of this License Agreement shall remain in full force and effect. This License Agreement
constitutes the entire agreement between the parties with respect to the use of the Software and
User Documentation and supersedes any and all prior oral or written agreements, discussions,
negotiations, commitments, or understandings. No amendment, modification, or waiver of any
provision of this License Agreement will be valid unless in writing and signed by the authorized
representative of the party against which such amendment, modification, or waiver is sought to be
enforced. The waiver by either party of any default or breach of this License Agreement shall not
constitute a waiver of any other or subsequent default or breach. This License Agreement shall be
binding upon the parties and their respective successors and permitted assigns.

1-2 CHAPTER 1
ERX System Overview
All models use the same software. However, the specific model
determines:
• The combination of line modules supported
• The conditions for line rate performance of line modules
ERX-1400 Series
In the ERX documentation, the term ERX-1400 series refers to both the
ERX-1440 system and the ERX-1410 system. The terms ERX-1440
system and ERX-1410 system refer to the specific models.
The ERX-1440 system manages an extremely high volume of network
traffic and uses a 40-Gbps switch route processor (SRP) module, either
the SRP-40G or SRP-40G+ module. (The SRP-40G+ module obsoletes
the SRP-40G module; however, the software continues to support both
modules.) In this model, all line modules operate at full wire speed
simultaneously.
The ERX-1410 system manages high levels of network traffic, and uses
the 10-Gbps SRP module (SRP-10G). You can configure the ERX-1410
system to enable the line modules either to operate at full line rate
performance or to allow line modules to operate at a rate dependent on
combinations of line modules. For information on configuring
performance of line modules, see ERX System Basics Configuration
Guide, Chapter 5, Managing Line Modules and SRP Modules.
Externally, the ERX-1440 chassis is the same as the ERX-1410 chassis
(see Figure 1-1 and Figure 1-2). Both systems contain fourteen vertical
slots to accommodate modules and have the same power requirements.
Installation procedures and operating procedures are identical for both
systems. All ERX systems use the same SRP I/O modules.
Note: The system may look different from the systems shown in the figures in this
chapter, depending on the line modules in the slots.
Internally, the ERX-1440 chassis differs from the ERX-1410 chassis, and
includes a special midplane for the 40-Gbps SRP module.

ERX-700 Series
In the ERX documentation, the term ERX-700 series refers to both the
ERX-705 system and the ERX-700 system. The terms ERX-705 system
and ERX-700 system refer to the specific models.
The ERX-705 system is a compact, high-performance model that
manages low traffic density and uses a 5-Gbps SRP module, the
SRP-5G+ module. The ERX-700 system is a robust, high-density system
with less capacity than the ERX-1400 series. The ERX-700 system uses
either the SRP-10G module or a 5-Gbps SRP module, the SRP-5G
module. (Although the SRP-5G+ module obsoletes the SRP-5G module;
the software continues to support both modules.)
You can configure the ERX-700 series to enable the line modules either
to operate at full line rate performance or to operate at a rate dependent
on the resources available. For information about configuring
performance of line modules, see ERX System Basics Configuration
Guide, Chapter 5, Managing Line Modules and SRP Modules.

SRP Module
The SRP module (see Figure 1-8) is a two-board assembly; both boards
connect to the system’s midplane and to each other:
• The fabric board is a switch fabric server that queues packets for the
line modules. The fabric server houses a flexible hardware queuing
resource that empowers IP QoS for each physical and logical interface,
providing weighted scheduling for preferential packet delivery.
system, manages diagnostics, and supports routing protocol
processing.
An SRP module must be present for the system to boot. For details about
installing SRP modules, see Chapter 3, Installing ERX Modules. For
specifications of SRP modules, see Appendix B, Module Specifications.
Caution: Do not remove the SRP module while the system is running.
You can install two SRP modules of the same type in the system. If you
do, the first SRP module serves as the primary; the second as a
redundant module, which enhances the system’s reliability. See
Redundancy Features, later in this chapter.
Nonvolatile Storage
The PCMCIA slot on the front of the SRP module holds a Type II
PCMCIA nonvolatile storage (NVS) card. This card retains the system’s
configuration and software. See Figure 1-8. The PCMCIA card is factory
installed.

SRP I/O Module
A single corresponding input/output module called the SRP I/O module
interfaces with one or two SRP modules through the system’s midplane.
The same SRP I/O works with all models of the SRP module. This I/O
module is two slots wide. See Figure 1-2 and Figure 1-4.
The SRP module provides standard craft management interfaces,
including:
• RS-232 – a port for VT100 management access
• External timing inputs – ports for external timing sources

Network Management Tools 1-11
ERX Edge Routers
I/O Modules
Most line modules have a corresponding input/output (I/O) module that
provides the physical interconnection to the network. Insert each I/O
module in the back of the system, directly behind its corresponding line
module. For information about which line modules pair with which I/O
modules, see Appendix B, Module Specifications. For details about
installing I/O modules, see Chapter 3, Installing ERX Modules.
Network Management Tools
You can use different management tools to configure the system to meet
the specific networking requirements.
CLI Management
The CLI provides fully developed and automated configuration and
status functionality through a local RS-232 port, an Ethernet connection,
or Telnet through any reachable network. For a full discussion of the CLI,
see ERX System Basics Configuration Guide, Chapter 2, Command
Line Interface.
SNMP MIB Management
The system offers a complete SNMP interface for configuration, status,
and alarm reporting. The system supports both Standard and Enterprise
MIBs (Management Information Bases). The ERX Enterprise MIB is
ASN.1 notated for easy importing into third-party SNMP management
applications. For more information, see ERX System Basics
Configuration Guide, Chapter 3, Configuring SNMP.
NMC-RX Device Management System
The NMX-RX application provides a global method of managing all
edge routers, line modules, and ports.
Redundancy Features
The system has the following redundancy features:
SRP Modules
The SRP module uses a 1:1 redundancy scheme. When two SRP
modules of the same type are installed in the system chassis, one acts as a
primary and the second as a standby. Both SRP modules share a single
Download from Www.Somanuals.com. All Manuals Search And Download.
1-12 CHAPTER 1
ERX System Overview
SRP I/O module located in the rear of the chassis. If the primary SRP
fails, the redundant SRP module assumes control without rebooting or
initializing itself. (As a consequence, if you upgrade software, you must
copy the software to the redundant SRP and reboot it.) For information
about configuring and managing SRP module redundancy, see ERX
System Basics Configuration Guide, Chapter 5, Managing Line Modules
and SRP Modules.
After you install two SRP modules, the modules negotiate for the primary
role. A number of factors determine which module becomes the primary;
however, preference is given to the module in the lower-numbered slot.
The SRP modules record their latest roles and retain them the next time
you switch on the system. For information about installing SRP modules,
see Chapter 3, Installing ERX Modules.
NVS Cards
If you have two SRP modules installed in a system, you can use NVS
cards of different capacities on the SRP modules. The effective capacity
of the higher-capacity NVS card will equal that of the lower-capacity
NVS card. For information about installing NVS cards, see Chapter 3,
Installing ERX Modules.
When you install new NVS cards or SRP modules, you must issue the
synchronize command to match the file system of the NVS card on the
redundant SRP module with the file system of the NVS card on the
primary SRP module. (The NVS card on the redundant SRP module will
hereafter be referred to as the redundant NVS card; the NVS card on the
primary SRP module will hereafter be referred to as the primary NVS
card.)
If the capacity of the primary NVS card is equal to or smaller than that of
the redundant NVS card, the system copies all the files from the primary
NVS card to the redundant NVS card. However, if the capacity of the
primary NVS card exceeds that of the redundant NVS card, the system
creates an invisible synchronization reserve file on the primary NVS
card, provided that there is enough space for the file.
The purpose of the synchronization file is to prevent the creation of data
that will not fit on the redundant NVS card. The file contains no useful
data, and is not visible when you view the files in NVS. The size of the file
is equal to the difference in capacities of the two NVS cards. For example,
if the primary NVS card has a capacity of 224 MB, and the redundant
NVS card has a capacity of 220 MB, the size of the synchronization file is
4 MB, and only 220 MB of space is available on the primary NVS card.

Redundancy Features 1-13
ERX Edge Routers
If there is not enough space on the primary NVS card to create the
synchronization reserve file, the synchronize command fails, and you
see a warning message on the console. To resolve this issue, either delete
unwanted files from the primary NVS card or replace the redundant
NVS card with a higher-capacity NVS card.
Line Modules
The ERX system supports line module redundancy for several line
modules. For details about which line modules support redundancy, see
Appendix B, Module Specifications. In this scheme, an extra line access
module in a group of identical line modules provides redundancy in case
of line module failure. To use this feature, you need a:
• Spare line module
• Redundancy midplane
• Redundancy I/O module
A redundancy midplane may cover 2–6 slots. It provides additional
connectivity that enables the spare line module to assume control of the
I/O module associated with any failed line module in the redundancy
group. The spare I/O module provides connectivity from the spare line
module to the redundancy midplane.
The process by which the system switches to the spare line module is
called switchover. When switchover occurs, the system:

Breaks the connection between the primary I/O module and the
primary line module.
Connects the primary I/O module to the spare line module via the
redundancy midplane and redundancy I/O module.
Protocol processing then takes place on the spare line module.

Power
The system provides a power architecture that distributes redundant
–48 VDC feeds through the system to each line module, SRP module,
and fan module where DC-to-DC converters provide local conversion to
the required secondary voltages. The system design prevents a failure of
any one of the power components from causing any other component in
the system to fail.

The Next Step 1-15
ERX Edge Routers
Fans
Forced air-cooling keeps the temperature of the ERX modules and
components within normal operating limits. In the ERX-1400 series, six
cooling fans are located in a tray at the top of the system (see Figure 7-5).
In the ERX-700 series, four cooling fans are located in a tray on one side
of the system (see Figure 7-7).
The system monitors the temperature of each module. If the temperature
of a module exceeds the maximum limit, the system immediately goes
into thermal protection mode. In this mode, the modules consume
extremely low levels of power. For information about troubleshooting
high operating temperatures, see Chapter 8, Troubleshooting.
The fan tray has two redundant converters that power the fans (for the
ERX-1400 series, a –24 V, 50 W converter; for the ERX-700 series, a
–12 V, 15 W converter). If one converter fails, the other takes over. In

Order of Installation
Before you attempt to install or replace a module (inserted in the front of
the chassis), the corresponding I/O module (inserted in the rear of the
chassis) should already be in place. The system diagnostics run when a
module is installed in a chassis slot. If the corresponding I/O module is
not present, the diagnostics fail, and you need to remove and reinsert the
module.

Safety Guidelines
Before and during the installation process, observe the following
precautions:
Lightning Activity Warning: Do not work on the system or connect or disconnect
cables during lightning activity.
DC Power Disconnection Warning: Before powering on the ERX system,
remove power from the DC circuit by deactivating the circuit breaker on the panel
board that services the DC circuit.
Jewelry Removal Warning: Remove jewelry (including rings, necklaces, and
watches) before working on equipment that is connected to power lines. Metal
objects heat up when connected to power and ground and can cause serious
burns or become welded to the terminals.
Metal Objects Warning: Do not insert any metal object, such as a screwdriver,
into an open slot or the backplane. Doing so may cause electric shock and serious
burns.
Repair Warning: Never attempt to repair parts of modules yourself. Only trained
customer service personnel are authorized to service parts. Call Juniper Networks
Customer Service to make arrangements to return defective modules for repair.
See Appendix F, Customer Service.

The Next Step
Setting Up Management Access
Before you power up the system, you must set up a management console.
The console allows you to communicate with the system during the
power-up process and to manage the system using the command line
interface (CLI).
You can manage and monitor the system by accessing it in the following
ways:
• Connect a console (PC, Macintosh, or UNIX workstation) directly to
the system’s RS-232 serial port (DTE).
• Connect the system’s 10/100Base-T port on the SRP I/O module to an
Ethernet network, and run Telnet from a remote console.
Download from Www.Somanuals.com. All Manuals Search And Download.
5-2 CHAPTER 5
Accessing the ERX System
For initial access to the system, you need to physically connect your
console directly to the system’s RS-232 port. This connection allows you
to use the CLI to set an IP address on the system. Once you configure the
IP address, you can access the system remotely (for example, via Telnet).
Console Port Setup
You can connect a console (PC, Macintosh, or UNIX workstation)
directly to the system via the RS-232 terminal port on the SRP I/O
module. When you connect a console directly to the system, you can
configure the system without an IP address.
To communicate with the system, you must have a terminal emulation
program running on your PC or Macintosh. You can use any terminal
emulation program (such as HyperTerminal). A UNIX workstation can
use the emulator TIP.
Using HyperTerminal
If your console uses a version of Microsoft Windows (such as Windows 95
or Windows NT 4.0) that supports the HyperTerminal application, you
can access the system via Hyperterminal.
1
Click the Start button and select Programs, Accessories, and
HyperTerminal.
2
3
In the HyperTerminal window, select HyperTerminal.
In the Connection Description window, enter a name for your router
(for example, erx1400) in the Name field.
4
5
Select any icon to represent your terminal emulation, and click OK.
In the Connect To dialog screen, in the Connect using field, select
the appropriate COM port to use (for example, COM1), and click
OK.
6
In the COM1 Properties screen, select the following settings:
• Bits per second: 9600
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: Xon/Xoff
Click OK.

Connecting Directly to the ERX System
When you connect a console directly to the system, use a cable
appropriate for your terminal connector. The cable must have a female
DB-9 connector to attach to the RS-232 port on the system. To connect a
console directly to the system:
1
Connect the female DB-9 connector to the RS-232 port on the
system’s SRP I/O module. See Figure 5-1.

3
Continue to configure the system’s parameters as needed.
After you have assigned an IP address to the system, you can
communicate remotely by running Telnet over an Ethernet network. See
the next section, Telnet Setup.
Telnet Setup
When you have configured an IP address for the system, you can run
Telnet on your console to access the system through its Ethernet port. To
connect the console to the system:
1
Connect an Ethernet cable (RJ-45) to the system’s 10/100Base-T
(RJ-45) port on the SRP I/O module.
2
Connect the other end of the cable to the appropriate Ethernet
network for an out-of-band connection.
Before you can access the system with Telnet, you must either configure a
password for Telnet access or disable the password requirement from the
management console. In the following example, you disable the
password.

Cleaning the System
Warning: Do not insert any metal object, such as a screwdriver, or place your hand
into an open slot or the backplane when the ERX system is on. Remove jewelry
(including rings, necklaces, and watches) before working on equipment that is
connected to power lines. These actions prevent electric shock and serious burns.
Caution: When cleaning the system, wear an antistatic wrist strap connected to
the system’s ESD grounding jack. This action helps to protect modules from
damage by electrostatic discharge.
Dust is attracted to the side of the system on which the air intake vent is
situated (see Figure D-2). Clean this side of the system with a dry cloth
every couple of weeks to prevent excessive accumulation of dust. This
cleaning will maintain the efficiency of the cooling system and prevent
damage to electronic components.
Replacing Fan Trays
A tray of cooling fans provides forced air cooling for components in the
on the model. The ERX-700 series and ERX-1400 series support
hot-swapping of the fan tray. Hot-swapping allows you to replace the fan
tray without powering down the system. However, if you do not replace
the fan tray within a few minutes, the system will go into thermal
protection mode. For information about thermal protection mode, see
Monitoring Temperatures of Modules in Chapter 8, Troubleshooting.
Caution: If the FAN FAIL LED on the SRP module is illuminated and none of the
fans are spinning when you remove the fan tray, power down the system until a
new fan tray is available. Operating an ERX system with inadequate air circulation
may damage the modules.

Diagnosing Problems
The information in this chapter can help you identify problems by
observing diagnostic signs. Your initial response to a system problem
should be to check power connections, observe the system’s LEDs
carefully, and check cable connections on the system modules.
Customer Service for instructions.
Power Failure
When you power up the system and it does not respond normally, refer to
the troubleshooting suggestions in Table 8-1.

8-2 CHAPTER 8
Troubleshooting
LED Activity
Module LEDs can show you the immediate status of a module and alert
you to a problem with the module or one of its ports. It is helpful to
familiarize yourself with LED activity so that you can easily detect and
correct a module-related problem with minimal or no system downtime.
activity. See Table 8-4 for specific information on troubleshooting
abnormal LED activity.
Module Cables
See Chapter 4, Cabling the ERX System, for information about cabling
modules.
Initialization Sequence
Each ERX line module is initialized independently. As a result, the CLI
on the SRP module may become available before the line modules have
completed initialization. Commands relating to a line module may fail if
the module has not completed initialization. The show version
command can be used to display line module status. Do not enter
commands for a line module until its state is “online.”
Troubleshooting Power Failures
The system’s distributed power system is designed to consume low levels
of power and dissipate low levels of heat. See Appendix A, System
Specifications for specifications of power consumption and heat
dissipation. If you suspect a power problem, refer to Table 8-1.

Understanding Status LEDs
When you power up the system, it runs a series of tests for each module
installed in the system. Refer to the tables in this section to understand
normal and abnormal LED activity. For troubleshooting information, see
Table 8-4.
LED Identification
The system’s modules have two sets of status LEDs. The top set indicates
generic router and module status. The bottom set indicates
module-specific status, such as port status (line modules) or fan status
(SRP module).
The number against the port status LED on a line module corresponds to
the number of the port on the I/O module. Some line modules have more
port status LEDs than the number of ports on the I/O module. In these
cases, only the LEDs for the corresponding ports on the I/O modules are
active.
For example, an OCx/STMx line module can pair with either an OC3-4
or an OC12/STM4 I/O module. Consequently, the line module has four
port status LEDs for OC3/STM1 operation. However, only the top two
sets of port status LEDs are active during OC12/STM4 operation.
Table 8-2 shows the functions of the module and port status LEDs.

Resetting Line Modules and SRP Modules 8-11
ERX Edge Routers
Resetting Line Modules and SRP Modules
Two recessed buttons on line modules and SRP modules provide the
mechanisms for resetting. You can use the NMI button to reset the
software on the module and the board reset button to reset the module.
See Figure 1-8 and Figure 1-9.
If a line module fails to respond for an extended period of time, there may
be a software problem with that module. You can depress the software
reset button with a paper clip to suspend the current software task.
Depending on the situation, this action may also reset the software on the
module.
If depressing the software reset button fails to correct the issue with the
line module, depress the board reset button. This action reboots the line
module.
The buttons work in the same way for the SRP module. Depressing the
board reset button on an SRP module is equivalent to rebooting the ERX
system and causes all the line modules to reboot.
Double-Bit Errors on SRP Modules
SRP modules include error checking and correction (ECC) to protect
their SDRAM. ECC provides error detection of single-bit and double-bit
errors and correction of single-bit errors for the SDRAM as follows:
• If ECC detects a single-bit error, it automatically corrects the error,
and operation continues.
• If ECC detects a double-bit error, it logs the error, stops the main
processor on the controller, and takes the SRP module offline.
Detecting Double-Bit Errors
The following message appears on the console if ECC detects a
double-bit error:
ALERT 05/10/2000 13:10:33 os: failed: ECC DOUBLE BIT ERROR
OCCURRED
Address = 0xe95db10
Data (Upper 32Bits) = 0xe95db20

8-12 CHAPTER 8
Troubleshooting
If ECC detects a double-bit error in a system that contains a redundant
SRP module, the redundant module becomes active and the system
continues to operate. However, you must still troubleshoot the SRP
module with the double-bit error. If ECC detects a double-bit error in a
system that does not contain a redundant SRP module, you must
troubleshoot the SRP module immediately. See Fixing Double-Bit Errors.
Fixing Double-Bit Errors
To f ix a double-bit error:
1
2
Remove the second SRP module, if there is one.
Reboot the system with the board reset button on the SRP module
(see Figure 1-8).
These actions attempt to correct a transient double-bit error. However, if
the console displays a memory test failure for the SRP module after you
reboot, or if the FAIL LED on the SRP module stays on during
rebooting, the SDRAM is permanently damaged and needs replacing. In
this event, call Juniper Networks Customer Service to arrange for repair.

SRP I/O Module
The SRP I/O module provides two management ports. You can connect
a console directly to the RS-232 serial port using a shielded
straight-through cable with a female DB-9 connector on one end and a
male DB-25 with a crossover adapter on the DB-25 end. This port is
called the serial port, the RS-232 port, or the console serial port.
Figure C-1 shows the location of the serial port and the sequence of the
pins in the RS-232 connector.

Overview
When installing new ERX software, you must mount the software CD on
a network host and transfer the release files to at least one ERX system in
the network. Depending on the network configuration, you can copy the
release files from either the network host or the first ERX system to the
other ERX systems in the network.
Identifying the Software Release File
The ERX system software CD contains two software releases: one for the
ERX-1440 system and one for all other ERX systems. Both releases are in
the software directory, which is identified by the release number. For

example, if the release number is x.y.z, the name of the directory is x-y-z.
To identify the software release file:
1
2
Access the software directory.
Find the files with the extension .rel.
• The software release file for the ERX-1440 system has the format
erx40_x-y-z.rel, where x.y.z is the release number.
• The software release file for all other ERX systems has the format
erx_x-y-z.rel, where x.y.z is the release number.
The procedures outlined in the following sections provide detailed
instructions for typical installations. For additional information about
commands and troubleshooting, refer to theERX System Basics
Configuration Guide and the ERX Command Reference Guide.
Installing Software When a Firewall Exists
When a firewall separates the ERX system from the network host, you
must FTP the software release files from the network host to the ERX
system. In this case, you must configure the FTP server on the ERX
system and ensure that FTP client software is installed on the network
host.
For this network configuration, you must install the software from the
normal operational mode of the command line interface (CLI). You can
access the CLI through either the local console or a Telnet session. If you
have not yet configured the ERX system to support Telnet, then you must
use the local console. See Chapter 5, Accessing the ERX System, for
information on using a local console or a Telnet session.
To install the software, perform the following tasks:

Before you install the software, obtain the following information:
• The password (if one is configured) that allows you to access Privileged
Exec mode on the ERX system
• The IP address of the network host
• The IP address of the ERX system
• The IP address of the next hop to reach the destination network (for
example, a gateway)
• The login name and password for the vty line
• The procedure for mounting a CD on the network host
Task 2: Access Privileged Exec Mode
To access this mode via the CLI:
1
2
Issue the enable command.
host1>enable
Type the password if the system prompts you.
Task 3: Configure IP on an Interface
Typically, you configure IP on the Fast Ethernet interface of the SRP
module. To configure IP on an interface:
1
Determine the slot number of the module.
host1#show version
2
3
Determine the port number of the module.
host1#show ip interface fastEthernet 6/0
Note: If an IP interface is not configured, you see the message “Invalid interface.”
If the interface already has an IP address, go to step 5. Otherwise,
proceed with step 4.

host1#ping hostname
If the ERX system cannot reach the network host, verify that you
performed the previous steps in this procedure correctly and that the
network host is operational.
Task 6: Enable the FTP Server on the ERX System
The ERX system divides its vty resources among Telnet, SSH, and FTP
services. Each FTP session requires one vty line, and the FTP service uses
the authentication method configured for the vty line. If you configured
more than one vty line for Telnet access, the FTP service will use one of
those lines. If you configured only one line for Telnet access, configure
another vty line. See Chapter 5, Accessing the ERX System.
To enable the FTP Server, use the ftp-server enable command.
host1(config)#ftp-server enable
Task 7: Identify the Files to Transfer
To identify all the files for the release, open the software release (.rel) file
on the ERX software CD with a text editor. The software release file
contains a list of all the files associated with the release. You must transfer
the software release file and all the files it contains to the user space.
Task 8: Transfer Files to the User Space
To transfer the files for the release to the ERX user space, use the FTP
client software on the network host to connect to the FTP server on the
ERX system. Transfer the files to a subdirectory within the incoming

Installing ERX System Software
directory. If you specify a subdirectory that does not exist, the ERX
system creates the directory.
Note: Be sure to transfer the software release file and all the files it lists.
Task 9: Install Files on the System Space
Installing the software release file to the system space installs all files listed
in the software release file. To install the software release file from the
incoming directory in the ERX user space to the ERX system space, use
the copy command.
Note: The destination file must have a .rel extension.
For example:
host1#copy /incoming/releases/x-y-z.rel x-y-z.rel
The software release will be copied from the network host to the
ERX system. This process can take several minutes.
Task 10: Save the Current Configuration
To save the current configuration, use the copy running-configuration
command:
host1#copy running-configuration filename.cnf
Task 11: Reboot the System
To reboot the system using the newly installed software:
1
Access Global Configuration mode.
host1#configure
Configuring from terminal or file [terminal]?
Enter configuration commands, one per line. End with CNTL/Z.
host1(config)#
2
Run the boot system command, specifying the .rel filename of the
software release.
For example:

Run the reload command.
host1#reload
The following message appears when you execute this command:
WARNING: Execution of this command will cause the system to
reboot. Proceed with reload? [confirm]
The system reboots. The reboot may take longer than normal
because line modules initialize with the old version of the software,
acquire the new version from the SRP module, and reinitialize.
When you observe the LEDs on the line modules, the line modules
appear to boot twice.
Installing Software When a Firewall Does Not Exist
If there is no firewall between the ERX system and the network host on
which you mount the software CD, you can transfer the software release
files from the network host to the ERX system via the ERX FTP server or
by issuing the copy command. To transfer files via the ERX FTP server,
refer to the previous section, Installing Software When a Firewall Exists.
This section describes how to transfer files by issuing the copy command.
If you use the copy command to transfer the files, the network host must
be an FTP server. This command activates a hidden FTP client on the
ERX system.
For this network configuration, you can install the software in the normal
command line interface (CLI) operational mode or in boot mode.
Installing Software in Normal Operational Mode
For this procedure, you must access the CLI through either the local
console or a Telnet session. If you have not yet configured the ERX
system to support Telnet, then you must use the local console. See
Chapter 5, Accessing the ERX System, for information on using a local
console or a Telnet session.

E-14 APPENDIX E
Installing ERX System Software
The software release will be copied from the network host to the
ERX system. This process can take several minutes.
Task 7: Reboot the System
To reboot the system using the newly installed software:
1
Run the boot system command, specifying the .rel filename of the
software release. For example:
:boot##boot system x-y-z.rel
The following message appears when you execute this command:
WARNING: It is recommended that you copy the current
running-configuration to a file prior to reloading a
different release of software.
2
Run the reload command.
:boot##reload
The following message appears when you execute this command:
WARNING: Execution of this command will cause the system to
reboot. Proceed with reload? [confirm]
The system reboots. The reboot may take longer than normal
because line modules initialize with the old version of the software,
acquire the new version from the SRP module, and reinitialize.
When you observe the LEDs on the line modules, the line modules
appear to boot twice.
Copying Release Files from One ERX System to Another
When you have copied the release files from a network host to one ERX
system, you can transfer files from that ERX system to other ERX
systems on the network. This feature is useful when:
• The other ERX systems are unreachable from the network host but
have network connectivity to the ERX system on which you installed
the new software.
• The connection between ERX systems is faster than the connection
between an ERX system and the network host to which it is connected.
The procedures for transferring release files from a source ERX system to
a destination ERX system are almost identical to transferring release files
from a network host to an ERX system on the same side of the firewall.
Note: You must enable the FTP server on the source ERX system.

ERX Edge Routers
To transfer release files from a source ERX system to a destination ERX
system, follow the instructions in Installing Software When a Firewall
Does Not Exist, with the following changes:
• Substitute the source ERX system for the network host.
• Omit the step about mounting the CD.
• Copy the file to the system space of the second ERX system from the
user space of the first ERX system.
host1#copy boston:/outgoing/releases/x-y-z.rel x-y-z.rel
Upgrading Systems That Are Operating with Two SRP Modules
Use this procedure if the system contains two SRP modules and is already
operating with an earlier software release. Each SRP module will keep
the system operational while you upgrade the software on the other, so
that you can avoid interrupting service.
Caution: You must upgrade the software on the redundant SRP module when you
upgrade the software on the primary SRP module. This action prevents the
redundant SRP module from overwriting the new software on the primary SRP
module if the primary SRP module fails and the redundant SRP module assumes
control.
To upgrade the software on a system that is operational and contains two
SRP modules:
1
Turn off autosynchronization.
host1(config)#disable-autosync
2
Copy the new release of the software to NVS of the primary SRP
module.
host1#copy host1:x-y-z.rel x-y-z.rel
3
4
Save the current configuration.
host1#copy running-configuration system2.cnf
Specify that the ERX system should use the new software release
when it reboots.
host1(config)#boot system x-y-z.rel
5
Synchronize the NVS file system of the redundant module to that of
the primary module.
host1#synchronize

E-16 APPENDIX E
Installing ERX System Software
The redundaant SRP module will automatically reboot, because the
software release that it is configured to run differs from the software
release it is running.
6
Wait for the redundant SRP module to boot, initialize, and reach the
standby state.
When the module is in standby state, the REDUNDANT LED is on
and the ONLINE LED is off. If you issue the show version
command, the state field for the module should be standby.
After any type of reboot, the primary and redundant SRP module
NVS file systems will be unsynchronized again.
7
8
Synchronize the NVS file system of the redundant module to that of
the primary module.
host1#synchronize
Switch from the primary SRP module to the redundant SRP
module.
host1#srp switch
