End User License Agreement

READ THIS END USER LICENSE AGREEMENT (“AGREEMENT”) BEFORE DOWNLOADING, INSTALLING, OR USING THE SOFTWARE. BY DOWNLOADING,

INSTALLING, OR USING THE SOFTWARE OR OTHERWISE EXPRESSING YOUR AGREEMENT TO THE TERMS CONTAINED HEREIN, YOU (AS CUSTOMER

OR IF YOU ARE NOT THE CUSTOMER, AS A REPRESENTATIVE/AGENT AUTHORIZED TO BIND THE CUSTOMER) CONSENT TO BE BOUND BY THIS

AGREEMENT. IF YOU DO NOT OR CANNOT AGREE TO THE TERMS CONTAINED HEREIN, THEN (A) DO NOT DOWNLOAD, INSTALL, OR USE THE

SOFTWARE, AND (B) YOU MAY CONTACT JUNIPER NETWORKS REGARDING LICENSE TERMS.

1. The Parties. The parties to this Agreement are Juniper Networks, Inc. and its subsidiaries (collectively “Juniper”), and the person or organization that

originally purchased from Juniper or an authorized Juniper reseller the applicable license(s) for use of the Software (“Customer”) (collectively, the “Parties”).

2. The Software. In this Agreement, “Software” means the program modules and features of the Juniper or Juniper-supplied software, and updates and

releases of such software, for which Customer has paid the applicable license or support fees to Juniper or an authorized Juniper reseller. “Embedded

Software” means Software which Juniper has embedded in the Juniper equipment.

3. License Grant. Subject to payment of the applicable fees and the limitations and restrictions set forth herein, Juniper grants to Customer a

non-exclusive and non-transferable license, without right to sublicense, to use the Software, in executable form only, subject to the following use restrictions:

a. Customer shall use the Embedded Software solely as embedded in, and for execution on, Juniper equipment originally purchased by Customer from

Juniper or an authorized Juniper reseller.

b. Customer shall use the Software on a single hardware chassis having a single processing unit, or as many chassis or processing units for which Customer

has paid the applicable license fees; provided, however, with respect to the Steel-Belted Radius or Odyssey Access Client software only, Customer shall

use such Software on a single computer containing a single physical random access memory space and containing any number of processors. Use of

the Steel-Belted Radius software on multiple computers requires multiple licenses, regardless of whether such computers are physically contained on a

single chassis.

c. Product purchase documents, paper or electronic user documentation, and/or the particular licenses purchased by Customer may specify limits to

Customer’s use of the Software. Such limits may restrict use to a maximum number of seats, registered endpoints, concurrent users, sessions, calls,

connections,subscribers,clusters,nodes,realms,devices,links,portsortransactions,orrequirethepurchaseofseparatelicensestouseparticularfeatures,

functionalities, services, applications, operations, or capabilities, or provide throughput, performance, configuration, bandwidth, interface, processing,

temporal, or geographical limits. In addition, such limits may restrict the use of the Software to managing certain kinds of networks or require the

Software to be used only in conjunction with other specific Software. Customer’s use of the Software shall be subject to all such limitations and purchase

of all applicable licenses.

d. For any trial copy of the Software, Customer’s right to use the Software expires 30 days after download, installation or use of the Software. Customer

may operate the Software after the 30-day trial period only if Customer pays for a license to do so. Customer may not extend or create an additional

trial period by re-installing the Software after the 30-day trial period.

e. The Global Enterprise Edition of the Steel-Belted Radius software may be used by Customer only to manage access to Customer’s enterprise network.

Specifically, service provider customers are expressly prohibited from using the Global Enterprise Edition of the Steel-Belted Radius software to support

any commercial network access services.

The foregoing license is not transferable or assignable by Customer. No license is granted herein to any user who did not originally purchase the applicable

license(s)fortheSoftwarefromJuniperoranauthorizedJuniperreseller.

4. Use Prohibitions. Notwithstanding the foregoing, the license provided herein does not permit the Customer to, and Customer agrees not to and shall

not: (a) modify, unbundle, reverse engineer, or create derivative works based on the Software; (b) make unauthorized copies of the Software (except as

necessary for backup purposes); (c) rent, sell, transfer, or grant any rights in and to any copy of the Software, in any form, to any third party; (d) remove any

proprietary notices, labels, or marks on or in any copy of the Software or any product in which the Software is embedded; (e) distribute any copy of the

Software to any third party, including as may be embedded in Juniper equipment sold in the secondhand market; (f) use any ‘locked’ or key-restricted

feature, function, service, application, operation, or capability without first purchasing the applicable license(s) and obtaining a valid key from Juniper, even

if such feature, function, service, application, operation, or capability is enabled without a key; (g) distribute any key for the Software provided by Juniper

to any third party; (h) use the Software in any manner that extends or is broader than the uses purchased by Customer from Juniper or an authorized

Juniper reseller; (i) use the Embedded Software on non-Juniper equipment; (j) use the Software (or make it available for use) on Juniper equipment thatthe

Customer did not originally purchase from Juniper or an authorized Juniper reseller; (k) disclose the results of testing or benchmarking of the Software to

any third party without the prior written consent of Juniper; or (l) use the Software in any manner other than as expressly provided herein.

5. Audit. Customer shall maintain accurate records as necessary to verify compliance with this Agreement. Upon request by Juniper, Customer shall

furnish such records to Juniper and certify its compliance with this Agreement.

6. Confidentiality. The Parties agree that aspects of the Software and associated documentation are the confidential property of Juniper. As such, Customer

shall exercise all reasonable commercial efforts to maintain the Software and associated documentation in confidence, which at a minimum includes

restricting access to the Software to Customer employees and contractors having a need to use the Software for Customer’s internal business purposes.

7. Ownership. Juniper and Juniper’s licensors, respectively, retain ownership of all right, title, and interest (including copyright) in and to the Software,

associated documentation, and all copies of the Software. Nothing in this Agreement constitutes a transfer or conveyance of any right, title, or interest in

the Software or associated documentation, or a sale of the Software, associated documentation, or copies of the Software.

8. Warranty, Limitation of Liability, Disclaimer of Warranty. The warranty applicable to the Software shall be as set forth in the warranty statement

that accompanies the Software (the “Warranty Statement”). Nothing in this Agreement shall give rise to any obligation to support the Software. Support

services may be purchased separately. Any such support shall be governed by a separate, written support services agreement. TO THE MAXIMUM EXTENT

PERMITTED BY LAW, JUNIPER SHALL NOT BE LIABLE FOR ANY LOST PROFITS, LOSS OF DATA, OR COSTS OR PROCUREMENT OF SUBSTITUTE GOODS

OR SERVICES, OR FOR ANY SPECIAL, INDIRECT, OR CONSEQUENTIAL DAMAGES ARISING OUT OF THIS AGREEMENT, THE SOFTWARE, OR ANY JUNIPER

OR JUNIPER-SUPPLIED SOFTWARE. IN NO EVENT SHALL JUNIPER BE LIABLE FOR DAMAGES ARISING FROM UNAUTHORIZED OR IMPROPER USE OF

ANY JUNIPER OR JUNIPER-SUPPLIED SOFTWARE. EXCEPT AS EXPRESSLY PROVIDED IN THE WARRANTY STATEMENT TO THE EXTENT PERMITTED BY

LAW, JUNIPER DISCLAIMS ANY AND ALL WARRANTIES IN AND TO THE SOFTWARE (WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE),

INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NONINFRINGEMENT. IN NO EVENT DOES

JUNIPER WARRANT THAT THE SOFTWARE, OR ANY EQUIPMENT OR NETWORK RUNNING THE SOFTWARE, WILL OPERATE WITHOUT ERROR OR

INTERRUPTION, OR WILL BE FREE OF VULNERABILITY TO INTRUSION OR ATTACK. In no event shall Juniper’s or its suppliers’ or licensors’ liability to

Customer, whether in contract, tort (including negligence), breach of warranty, or otherwise, exceed the price paid by Customer for the Software that gave

rise to the claim, or if the Software is embedded in another Juniper product, the price paid by Customer for such other product. Customer acknowledges

and agrees that Juniper has set its prices and entered into this Agreement in reliance upon the disclaimers of warranty and the limitations of liabilityset

forth herein, that the same reflect an allocation of risk between the Parties (including the risk that a contract remedy may fail of its essential purpose and

cause consequential loss), and that the same form an essential basis of the bargain between the Parties.

9. Termination. Any breach of this Agreement or failure by Customer to pay any applicable fees due shall result in automatic termination of the

license granted herein. Upon such termination, Customer shall destroy or return to Juniper all copies of the Software and related documentation in

Customer’s possession or control.

10. Taxes. All license fees for the Software are exclusive of taxes, withholdings, duties, or levies (collectively “Taxes”). Customer shall be responsible

for paying Taxes arising from the purchase of the license, or importation or use of the Software.

11 . Export. Customer agrees to comply with all applicable export laws and restrictions and regulations of any United States and any applicable foreign

agency or authority, and not to export or re-export the Software or any direct product thereof in violation of any such restrictions, laws or regulations, or

without all necessary approvals. Customer shall be liable for any such violations. The version of the Software supplied to Customer may contain encryption

or other capabilities restricting Customer’s ability to export the Software without an export license.

12. Commercial Computer Software. The Software is “commercial computer software” and is provided with restricted rights. Use, duplication, or

disclosure by the United States government is subject to restrictions set forth in this Agreement and as provided in DFARS 227.7201 through 227.7202-4,

FAR 12.212, FAR 27.405(b)(2), FAR 52.227-19, or FAR 52.227-14(ALT III) as applicable.

13. Interface Information.To the extent required by applicable law, and at Customer’s written request, Juniper shall provide Customer with the

interface information needed to achieve interoperability between the Software and another independently created program, on payment of applicable

fee, if any. Customer shall observe strict obligations of confidentiality with respect to such information and shall use such information in compliance

with any applicable terms and conditions upon which Juniper makes such information available.

14. Third Party Software.Any licensor of Juniper whose software is embedded in the Software and any supplier of Juniper whose products or technology

are embedded in (or services are accessed by) the Software shall be a third party beneficiary with respect to this Agreement, and such licensor or vendor

shall have the right to enforce this Agreement in its own name as if it were Juniper. In addition, certain third party software may be provided with the

Software and is subject to the accompanying license(s), if any, of its respective owner(s). To the extent portions of the Software are distributed under and

subject to open source licenses obligating Juniper to make the source code for such portions publicly available (such as the GNU General Public License

copy of the LGPL at http://www.gnu.org/licenses/lgpl.html.

15. Miscellaneous. This Agreement shall be governed by the laws of the State of California without reference to its conflicts of laws principles. The

provisions of the U.N. Convention for the International Sale of Goods shall not apply to this Agreement. For any disputes arising under this Agreement,the

Parties hereby consent to the personal and exclusive jurisdiction of, and venue in, the state and federal courts within Santa Clara County, California.

This Agreement constitutes the entire and sole agreement between Juniper and the Customer with respect to the Software, and supersedes all prior and

contemporaneous agreements relating to the Software, whether oral or written (including any inconsistent terms contained in a purchase order), except

that the terms of a separate written agreement executed by an authorized Juniper representative and Customer shall govern to the extent such terms are

inconsistent or conflict with terms contained herein. No modification to this Agreement nor any waiver of any rights hereunder shall be effective unless

expressly assented to in writing by the party to be charged. If any portion of this Agreement is held invalid, the Parties agree that such invalidity shall not

affect the validity of the remainder of this Agreement. This Agreement and associated documentation has been written in the English language, and

the Parties agree that the English version will govern. (For Canada: Les parties aux présentés confirment leur volonté que cette convention de même

que tous les documents y compris tout avis qui s’y rattaché, soient redigés en langue anglaise. (Translation: The parties confirm that this Agreement

Overview

ERX routers are modular, carrier-class networking devices that deliver performance,

reliability, and service differentiation to both business and consumer Internet

users. The ERX-7xx and ERX–14xx models offer high port density, low power

consumption, and fully redundant Internet access routing and edge aggregation. The

ERX-310 router supports the same services, but with smaller capacity and scaling

capabilities. ERX routers offer the complete edge solution for IP-optimized carriers.

ERX Routers

Five models of ERX routers are available:

ERX-1440 router

ERX-1410 router

ERX-710 router

ERX-705 router

ERX-310 router

ERX-14xx Models

NOTE: In the E-series documentation, the term ERX-14xx models refers to both

the ERX-1440 router and the ERX-1410 router. The terms ERX-1440 router and

ERX-1410 router refer to the specific models. See Figure 1 and Figure 2.

The ERX-1440 router 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 router manages high levels of network traffic, and uses the

10-Gbps SRP module (SRP-10G). You can configure the ERX-1410 router to

enable the line modules either to operateatfulllinerateperformanceorto

allow line modules to operate at a rate dependent on the resources available.

The former option restricts the allowed combinations of line modules. For

information on configuring performanceoflinemodules,seeJUNOSe System

Basics Configuration Guide, Chapter 6, Managing Modules.

NOTE: The 10-Gbps SRP module used in the ERX-310 router is different from the

10-Gbps SRP module used in the ERX-1410 router. See “SRP Module” on page 10

for more information.

Externally, the ERX-1440 chassis is the same as the ERX-1410 chassis. (See Figure 1

and Figure 2.) Both routers contain 14 vertical slots to accommodate modules.

Internally, the ERX-1440 chassis differs from the ERX-1410 chassis, and

includes a special midplane for the 40-Gbps SRP module.

Installation procedures and operating procedures are identical for both

systems. All ERX-7xx and ERX-14xx models use the same SRP I/O module,

but different power input modules are used.

NOTE: The router may look different from the routers shown in the figures in this

chapter, depending on the line modules in the slots.

router refer to the specific models. See Figure 3 and Figure 4.

The ERX-7xx models are robust, high-density routers with less capacity

than the ERX-14xx models. The ERX-7xx models use either the

SRP-10G module or the SRP-5G module.

The ERX-705 chassis is the same as the ERX-710 chassis. (See Figure 3 and Figure 4.)

The chassis contains seven slots to accommodate modules. Installation procedures

ERX-310 Router

The ERX-310 router is a low-end platform that supports all of the same services

as the ERX-7xx and ERX-14xx models, but with smaller capacity and scaling

capabilities. Like the ERX-7xx and ERX-14xx models, the ERX-310 router

uses the same software architecture, providing a single IP entry point into

the network with the same IP-based protocols and services that are available

on other ERX routers. The ERX-310 router is designed to be used as a small

distributed POP router as well as a high-end CPE router.

The ERX-310 router is a three-slot chassis with a midplane architecture. One slot

supports one nonredundant 10-Gbps SRP module, while the other two slots support

line modules. The router supports existing E-series ASIC-based line modules (except

the OC48/STM16 line module), as well as a select number of combination cards.

The combination cards provide a fixed combination of interfaces on the I/O module

so that a single slot can support multiple interfaces (ATM OC3 and GE, for example).

NOTE: The 10-Gbps SRP module used in the ERX-310 router is different from

the 10-Gbps SRP module used in the ERX-7xx and ERX-14xx models. See “SRP

Module” on page 10 for more information.

The ERX-310 router is available in either redundant AC- or DC-powered models.

ERX Modules

Each system supports an SRP module and a selection of line modules. You can

use any line module for access or uplink . Access line modules receive traffic

from low-speed circuits, and the system routes the traffic onto higher-speed

uplink line modules and then to the core of the network.

Each moduleconnectstoacorrespondingI/Omoduleviaapassive

midplane. See Figure 8.

The front panel of each module contains a collection of status LEDs

(light-emitting diodes). For information about how to interpret the

LEDs, see “Troubleshooting” on page 103.

SRP Module

Switch route processor (SRP) modules perform system management, routing

table calculations and maintenance, forwarding table computations, statistics

processing, configuration storage, and other control plane functions. Each

SRP module is a PowerPC-based system with its own memory, nonvolatile

disk storage, and power supply. (See Figure 9 and Figure 10.)

Module Details

ERX-7xx and ERX-14xx models use up to two redundant SRP modules operating

in an active/standby configuration. ERX-310 routers use only one SRP module.

An SRP module must be present for any system to boot.

SRP modules ranging from 5 Gbps to 40 Gbps can be used in ERX-7xx and

ERX-14xx models. Only a 10-Gbps SRP module (SRP-SE10G) can be used in

ERX-310 routers. See the ERX Module Guide for complete information.

NOTE: Because of different physical dimensions and switch fabric capabilities, SRP

modules are not interchangeable between systems. For example, the 10-Gbps SRP

module used in ERX-7xx and ERX-14xx models cannot be used in the ERX-310

router, and vice versa.

12 ERX Modules

ERX Overview

CAUTION: Do not remove the SRP module while the system is running.

NOTE: Some SRP modules require a minimum amount of memory to be used

with JUNOSe Release 5.3.0 or a higher-numbered release. See the ERX Module

Guide for module specifications.

For details about installing SRP modules, see “Installing Modules” on page 35.

SRP Module Redundancy

SRP module redundancy is available only for ERX-7xx and ERX-14xx models.

See “Redundancy Features” on page 16 for more information.

Nonvolatile Storage

ThePCMCIAslotonthefrontoftheSRPmoduleholdsaTypeIIPCMCIAnonvolatile

storage (NVS) card. (See Figure 9 and Figure 10.) This card is loaded with the

system’s software and configuration files. The PCMCIA card is factory installed.

CAUTION: Although you can remove PCMCIA NVS (Flash) cards from a running

router, we recommend that you do not do so. If you remove the card while data is

being written to or copied from the NVS card, data can be lost or corrupted.

Therefore, we strongly recommend that you shut down the router before removing

a PCMCIA NVS card.

SRP I/O Module

The SRP I/O module is a single corresponding input/output module that interfaces

with the SRP modules through the system’s midplane. The same SRP I/O module

works with all SRP modules, but is router specific. The I/O module used in

ERX-7xx and ERX-14xx models cannot be used in the ERX-310 router, and

vice versa. See Figure 2, Figure 4, and Figure 6 for locations.

Module Details

The SRP I/O module provides standard craft management interfaces, including:

10/100Base-T—The port enables access to the ERX router for Ethernet

management functions via CLI or SNMP, for example.

ERX Modules 13

ERX 8.0.x Hardware Guide

RS-232—The port provides a serial connection for monitoring the system’s

hardware configuration through a PC (running terminal emulation software) or

ASCII terminal. Allows direct CLI access.

Alarm contacts—The contacts provide for remote indication of critical, major,

and minor router alarms (ERX-7xx andERX-14xxmodelsonly;currently

not implemented)

External timing inputs—The inputs provide a method of ensuring that the

clock timing used by the router remains synchronized with the network’s

system clock. BNC connectors and wire wraps are available for ERX-7xx

and ERX-14xx models only.

For details about installing the SRP I/O module, see “Installing Modules” on page 35.

Line Modules

Line modules (LM) process data from different types of network connections.

For information about available line modules and which SRP modules support

specific line modules, see the ERX Module Guide.

Figure 11 shows a representative line module. For details about installing

line modules, see “Installing Modules” on page 35.

Packet Classification

Most line modules support packet classification on ingress; some non-ASIC line

modules do not. A classification engine on the line module matches specific

fields (such as source and destination IP address, source and destination port,

and protocol), the ingress IP interface, layer 2 fields, or some combination

of these against user-configured filters at wire speed.

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 into the

back of the system, directly behind its corresponding line module.

For information about which line modules pair with which I/O modules, see the

ERX Module Guide. See Figure 2, Figure 4, and Figure 6 for locations. For details

about installing I/O modules, see “Installing Modules” on page 35.

ERX Modules 15

ERX 8.0.x Hardware Guide

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, Telnet, or SSH via any reachable

network. For a full discussion of the CLI, see JUNOSe 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 Juniper Networks E-series

Enterprise MIB is ASN.1 notated for easy importing into third-party SNMP

management applications. For more information, see JUNOSe System Basics

Configuration Guide, Chapter 4, Configuring SNMP.

NMC-RX Device Management System

The NMX-RX application provides a global method of managing all routers,

line modules, and ports through a graphical user interface.

Redundancy Features

This section describes system redundancy features.

SRP Modules

NOTE: This section applies to ERX-7xx and ERX-14xx models only. ERX-310 routers

contain one SRP module and therefore do not offer SRP module redundancy.

ERX-7xx and ERX-14xx models use a 1:1 redundancy scheme for the SRP module.

When two SRP modules of the same type are installed in the chassis, one acts as a

primary (active) and the second as a redundant (standby) module. Both SRP

modules share a single SRP I/O module located in the rear of the chassis.

If the standby SRP module detects that the primary SRP module is not active

(and high-availability mode is not enabled), it reboots the system and takes

control. If high-availability mode has been enabled, automatic switchover

occurs with near hitless failover. 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 JUNOSe System

Basics Configuration Guide, Chapter 6, Managing Modules.

16 Redundancy Features

ERX Overview

After you install two SRP modules, the modules negotiate for the primary role.

Anumberoffac

tors 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 “Installing Modules” on page 35.

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 “Installing Modules” on page 35.

When you install new NVS cards or SRP modules, you must issue the synchronize

command to matchthefilesystemoftheNVScardontheredundantSRP

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

cannot 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.

If the primary NVS card does not have enough space to create the synchronization

reserve file, the synchronize command fails, and a warning message is displayed

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

NOTE: This section applies to ERX-7xx and ERX-14xx models only. ERX-310 routers

do not offer line module redundancy.

ERX-7xx and ERX-14xx models support line module redundancy for several

line modules. For details about which line modules support redundancy,

see the ERX Module Guide. In this scheme, an extra line module in a group

Redundancy Features 17

of identical line modules provides redundancy in case of line module

failure. To use this feature, you need a:

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:

1. BreakstheconnectionbetweentheprimaryI/Omoduleandtheprimary

2. 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.

Configuration Guide, Chapter 6, Managing Modules.

Power

All E-series routers provide a power architecture that distributes redundant –48 VDC

feeds through the router to each line module, SRP module, and fan module where

DC-to-DC converters provide local conversion to the required secondary voltages.

The ERX-310 router is available with either DC or AC power inputs. The AC-powered

version can be configured with one or two hot-swappable power supplies for optional

redundancy. (See Figure 5 and Figure 6.) The power supplies convert AC power to

internal –48 V redundant DC feeds that are then distributed through the router.

Redundancy Features 19

ERX 8.0.x Hardware Guide

Fans

Forced air-cooling keeps the temperature of the E-series modules and components

within normal operating limits. In ERX-14xx models, six cooling fans are located

in a tray at the top of the router (Figure 1). In ERX-7xx models, four cooling fans

arelocatedinatrayononesideoftherouter(Figure3). IntheERX-310router,

two cooling fans are located in a tray on one side of the router (Figure 5).

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 and the modules are powered off. The ERX system controller

enters a low power mode, keeps the modules in a power-off condition, and does

not respond to any management interface commands. For information about

troubleshooting high operating temperatures, see “Troubleshooting” on page 103.

In ERX-7xx and ERX–14xx models, the fan tray has two redundant converters

that power the fans (for the ERX-14xx models, a –24 V, 50 W converter; for the

ERX-7xx models, a –12 V, 15 W converter). If one converter fails, the other

takes over. The ERX-310 router does not have redundant converters.

For all E-series routers, the system software reports an alarm if any

of the fans or converters fail.

Preparing the Equipment Racks

Following your installation plan, use a tape measure and marking pen to measure

and mark space on each equipment rack for each router component. For horizontal

spacing, follow Network Equipment Building System (NEBS) requirements. If you

choose not to install a plenum, be sure to include 2 U of space between each

chassis for proper exhaust. A plenum, however, is highly recommended.

Installing the Router

To complete the installation of the router in a rack, you need:

A Phillips screwdriver

Depending on the router, up to eight 10-32 x 3/8 Phillips screws (provided with

the router) for each router to be installed

WARNING: Three people are required to install the router in a rack: two to lift the

system into position and one to screw it to the rack.

CAUTION: Make sure all persons handling a router wear an antistatic device.

To install the router in the rack:

1. With one person standing on the left side of the router and another standing

on the right side, lift the router into the rack.

2. Position the router in its designated location in the equipment rack. Make

sure the holes of the mounting brackets align evenly with the holes of the

equipment rack on both sides.

3. Starting at the bottom, have the third person secure the router in the

equipment rack by using the 10-32 x 3/8 Phillips screws.

4. Connect the necessary cables. (See “Cabling ERX Routers” on page 53 for

Combinations of Line Modules In Slot Groups

For information about combinations of line modules in slot groups, see JUNOSe

System Basics Configuration Guide, Chapter 6, Managing Modules.

OC48 Line Modules

The ERX-1440 router with the SRP-40G+ SRP module supports OC48 line

modules. Other ERX routers do not support OC48 line modules.

An OC48 line module spans two slots in an ERX-1440 router. You can

install this line module only in slots 2–3 and slots 4–5. Other slots in

the system do not support this line module.

The corresponding OC48 Frame APS I/O module spans only one slot. Install the I/O

module in the lower of the slots (either slot 2 or slot 4) that the line module spans.

GE-2 Line Modules

The ERX-1440 router with the SRP-40G+ SRP module supports GE-2 line

modules in all slots; however, full bandwidth is delivered only when the line

module is in slot 2 or slot 4. The line module can be used with other SRP

modules, but maximum line performance will not be achieved.

The ERX-310 router with the SRP-SE10G SRP module supports GE-2 line modules in

both slots (1 and 2). Maximum line performance is achieved in either slot.

Other ERX routers do not support GE-2 line modules.

Managing Modules Using the Software

For information about software procedures associated with replacing

and managing modules, see JUNOSe System Basics Configuration

Guide, Chapter 6, Managing Modules.

Hot-Swapping Modules

All ERX routers support hot-swapping of modules. Hot-swapping enables you

toaddorremoveamodulewithoutpoweringdownthesystem.

Protecting Modules and Slots

Each ERX chassis has an ESD (electrostatic discharge) grounding jack. See

Table 4 for locations. To prevent damage from electrostatic discharge, connect

an antistatic wrist strap to the jack when handling components.

Overview 39

ERX 8.0.x Hardware Guide

CAUTION: If you meet strong resistance when attempting to seat the module using

the ejectors, remove it from the chassis and confirm that the slot is designed to hold

the module. Then verify, if applicable, that the module matches its corresponding

module (I/O module or line module). Also, be sure that you have aligned the top

and bottom edges in the correct matching tracks.

CAUTION: Be sure to cover every empty slot with a blank filler panel to protect the

system from dust or other foreign substances and to ensure proper system cooling.

CAUTION: Do not discard the antistatic bag. When a module is not in use, store it

in an antistatic bag.

Order of Installation

Before you attempt to install or replace a line module (inserted in the front of

the chassis), make sure the corresponding I/O module (inserted in the rear of

the chassis) is already in place. The slot diagnostics run when a line 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.

54 Cabling Overview

Cabling ERX Routers

Required Tools, Wires, and Cables

Cabling your system takes only a few minutes. You need the following

items and those listed in Table 7 for proper installation:

1/8–inch flathead screwdriver

3/8–inch wrench or 3/8–inch nut-driver

No. 2 Phillips screwdriver

Ground wires—We recommend a minimum of 10-AWG ground wire.

#10 (ERX-7xx and ERX-14xx models) or #8 (ERX-310 router) kep nut to

connect the ground (earth) wire to the ground terminal.

Power input module wiring—We recommend a minimum of 8-AWG wire for

ERX-14xx models, 12-AWG wire for ERX-7xx models, and 14-AWG wire for

ERX-310 routers (DC model) with a dual stud terminal lug with 5/8–inch

spacing. For the ERX-310 router AC model, use a standard IEC power cord.

Consider the distance from the connection point and the configuration of the

system when determining the size of wire used.

See “System Specifications” on page 119 for more information on router

specifications.

NOTE: If you plan to use a cable-management bracket (ERX-7xx and ERX-14xx

models only), install it before you begin cabling your router. Cable-management

brackets are helpful to keep network interface cables untangled and orderly

and to prevent cables from hindering access to other slots. See “Installing a

Cable-Management Bracket on ERX-7xx Models” on page 100.

Required Tools, Wires, and Cables 55

ERX 8.0.x Hardware Guide

Cabling the SRP I/O Module

Before powering up the router, you must set up a management console. The

console enables you to communicate with your system during the power-up process

and to manage your system using the command-line interface (CLI).

When connecting a console directly to the SRP I/O module, use a cable appropriate

foryourterminalconnector.ThecablemusthaveafemaleDB-9connectortoattach

to the RS-232 port on the SRP I/O module. See Figure 24 and Figure 25.

The console port is considered a data terminal equipment interface

(DTE). Direct connection to a terminal or PC (which also have DTE

interfaces) requires a crossover cable.

NOTE: The alarm function on the SRP I/O module is currently not implemented.

Only ERX-7xx and ERX-14xx models have external timing ports and alarm leads

located on the SRP I/O module. All ERX routers have console ports located on

the SRP I/O module. See Table 8 for details on each component.

router does not support external timing.

56 Cabling the SRP I/O Module

Cabling ERX Routers

The SRP I/O module has two input ports for external clock sources.

These ports provide a way to ensure that the router system clock remains

synchronized with the network’s system clock. The primary clock is labeled

A; the secondary, redundant clock is labeled B.

Use the connectors appropriate for your locale (European or

North American standard):

European—Two 75-ohm E1 2.048-Mbps inputs with BNC connectors

North American—Two 100-ohm T1 inputs with three pin wire-wrap

connectors. Pins are labeled T (tip), G (ground), and R (ring). We recommend

using 26-AWG wire minimum.

NOTE: Use shielded cables to connect the external clock sources to the clock

source input ports.

3. Repeat Steps 1 and 2 for the Clock B connections.

Management Ports

NOTE: This section applies to all ERX routers.

The Console section of the SRP I/O module has two ports for management

access. (See Figure 24 and Figure 25.)

The 10/100Base-T Ethernet port accepts an RJ-45 (male) connector, providing

an out-of-band connection for LAN access through a Telnet session or SNMP.

The RS-232 port accepts a DB-9 (female) connector for direct CLI access

from a console terminal.

The console port is considered a data terminal equipment interface (DTE).

Direct connection to a terminal or PC (which also have DTE interfaces) requires

a crossover cable.

Connecting to the Network

To connect the router to the network:

1. Insert an Ethernet cable (RJ-45) connector into the 10/100Base-T (RJ-45) port

on the SRP I/O module until it clicks into place.

2. Connect the other end of the cable to the appropriate Ethernet network for

an out-of-bandconnection.

Connecting to a Console Terminal

When you connect a console directly to the router SRP I/O module, 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 SRP I/O module.

To connect the console to the SRP I/O module:

1. InsertthefemaleDB-9connectorintotheRS-232port,andtightenthescrews.

2. Connect the other end of the cable to your terminal’s serial port (VT100/ANSI).

Cabling the Router for Power

After you have correctly cabled the modules and I/O modules, you

must attach grounding and electrical wires before you attempt system

power-up. Three main tasks are involved:

1. Switch all router power switches to OFF.

CAUTION: Switches may have inadvertently flipped to ON during shipping and

installation.

2. Connect the grounding wires to the chassis.

WARNING: Always connect the grounding wires first (before connecting the power

cables) and disconnect them last when installing or servicing the router.

3. Connect the power cables (AC or DC) to the power input modules.

See “System Specifications” on page 119 for the power requirements for ERX

routers. Table 9 identifies the power input module cabling requirements, and

Figure 26 shows the main components of a power input module.

62 Cabling the Router for Power

Cabling ERX Routers

Task 2: Connect the Grounding Cables

All ERX routers have two grounding studs located in the rear of the chassis, near

the power inputs. Each stud provides grounding for a single power unit.

To ground each power unit:

1. Locate the grounding studs on the router (Figure 26 and Figure 27).

2. Remove the nuts and locking washers from the grounding studs.

NOTE: We recommend a minimum of 10-AWG ground wire with a ring style

terminal.

3. Place the grounding cable lead on one of the grounding studs and tighten

the nuts to secure the connection.

4. Connect the other end of the ground cable to the appropriate ground

termination lead.

5. Repeat Steps 3–4 for the remaining grounding stud.

NOTE: When grounding an ERX router, leave a service loop in the grounding cable

to ensure that the grounding cable is the last cable to disconnect from the shelf if

strain is placed on the electrical cables.

Task 3: Connect the Power Cables

To connect power cables to the router, follow these steps. Refer to

Figure 26, Figure 27, and Figure 28 as needed.

Powering Up 73

ERX 8.0.x Hardware Guide

NOTE: In this procedure, we assume that the system is already connected to a

power source. See “Cabling ERX Routers” on page 53.

CAUTION: Evaluate the overall loading of the branch circuit before you install

any equipment into a rack.

To power up the system:

1. Verify that the power source is operational and turned on.

2. Inspect all grounding and power connections to the router chassis.

3. Confirm that all connections are secure.

4. Switch the powerswitchestoON.

5. Monitor the LEDs on the front of the SRP modules to verify that the system

is booting properly. See Table 12 in “Troubleshooting” on page 103 for LED

status explanations.

When the prompt appears on the system console, the system is in User Exec

mode and is ready to be configured:

host1>

6. Enter the enable command to access Privileged Exec mode:

host1>enable

host1#

In Privileged Exec mode you can begin to configure the system. See JUNOSe

System Basics Configuration Guide, Chapter 2, Command-Line Interface for

more information.

Initialization Sequence

Each line module is initialized independently. As a result, the CLI on the SRP

module can become available before the line modules have completed initialization.

Commands relating to a line module might fail if the module has not completed

initialization. You can use the show version command to display line module

status. Do not enter commands for a line module until its state is listed as online.

74 Powering Up

Powering Up ERX Routers

Status LEDs

Upon initial power-up, the components of the router run boot code, go through

a series of self diagnostic tests, and synchronize with each other.

When the tests are complete, use the LEDs on each module to determine the

status of the router. Observe the line module and SRP module LEDs in the front,

and the I/O line module and SRP I/O module LEDs in the rear.

See “Troubleshooting” on page 103 for information on the system’s LEDs.

Powering Down

If you need to power down or remove the SRP module, first enter the halt

command to temporarily suspend the system’s operation. See JUNOSe System

Basics Configuration Guide, Chapter 5, Managing the System for more information.

CAUTION: Ifyoudonotusethehalt command before removing or powering down

an SRP module, the system’s NVS card might become corrupted.

If you shut down the system improperly, it runs an investigation of the

file allocation table (FAT) the next time it reboots.

Chapter 7

Accessing ERX Routers

This chapter discusses how to access the system to manage it. Managing your

router includes both configuring and monitoring it. For basic information on

the management of the system, see JUNOSe System Basics Configuration Guide,

Chapter 5, Managing the System.

This chapter contains the following sections:

Setting Up Management Access on page 77

Console Port Setup on page 78

Telnet Setup on page 80

SNMP on page 82

The Next Step on page 82

Setting Up Management Access

Before you power up the system, you must set up a management console.

(See “Connecting to a Console Terminal” on page 60.) You use the console to

communicate with the system during the power-up process, set an IP address,

andmanagethesystemusingthecommand-lineinterface(CLI).

You can manage and monitor the router through either of these methods:

Console terminal—Connect a console (PC, Macintosh, or UNIX workstation)

directly to the system’s RS-232 serial port.

Remote console—Connect the 10/100Base-T port on the SRP I/O module to an

Ethernet network, and run Telnet from a remote console.

For initial access to the system, you need to physically connect your console

directly to the system’s RS-232 port. Through this connection you can use the

CLI to set an IP address on the system. After you configure the IP address,

you can access the system remotely (for example, via Telnet).

Setting Up Management Access 77

ERX 8.0.x Hardware Guide

Console Port Setup

You can connect a console terminal (PC, Macintosh, or UNIX workstation) directly

to the SRP I/O module via the RS-232 terminal port. 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. In the HyperTerminal window, select HyperTerminal.

3. In the Connection Description window, enter a name for your router (for

example, erx1400)intheNamefield.

4. Select any icon to represent your terminal emulation, and click OK.

5. In the Connect To dialog box, in the Connect using field, select the appropriate

COM port to use (for example, COM1), and click OK.

6. In the COM1 Properties window, select the following settings:

Bits per second: 9600

Data bits: 8

Parity: None

Stop bits: 1

Flow control: Xon/Xoff

7. Click OK.

Connecting Directly to the Router

When you connectaconsoledirectlytothesystem,useacableappropriate

for your terminal connector. The cable must have a female DB-9 connector

to attach to the RS-232 port on the system.

The console port is considered a data terminal equipment interface

(DTE). Direct connection to a terminal or PC (which also have DTE

interfaces) requires a crossover cable.

78 Console Port Setup

Accessing ERX Routers

To connect a console directly to the system:

1. ConnectthefemaleDB-9connectortotheRS-232portonthesystem’sSRP

I/O module. SeeFigure36.

Figure 36: Management Ports for ERX Routers

2. Connect the crossover adapter connector to your PC’s serial port.

3. Power up the system.

When you power up the system, the CLI appears on your console’s screen.

The system is now in User Exec mode, and you can begin configuration. For

more information on using the CLI and configuring the system, see the JUNOSe

Console Port Setup 79

ERX 8.0.x Hardware Guide

Assigning an IP Address

When your console is ready to communicate with the system, power up the system.

(See “Powering Up ERX Routers” on page 73.) Then set an IP address for the

system. The system powers up in User Exec mode. To assign an IP address:

1. Enter the enable command at the User Exec prompt.

host1>enable

host1#

The system is now in Privileged Exec mode.

2. SetanIPaddre

ss on the Ethernet interface:

Substitute the slot number where the SRP module is located for the

slotnumber variable. For redundant SRP modules, specify the lowest slot

number of the two (for example 0/0 or 6/0 ).

UseanIPaddressvalidforthesystem.

host1#configure terminal

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

host1(config)#interface FastEthernet slotnumber /0

host1(config-if)#ip address 10.10.7.3 255.255.255.0

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 “Telnet Setup” on page 80.

Telnet Setup

After you have configured an IP address for the system, you can run

Telnet from a host to access the system through its Ethernet port. To

connect the Ethernet port to the network:

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.

1. Enter the enable command.

host1>enable

host1#

The system is now in Privileged Exec mode.

ERX 8.0.x Hardware Guide

CAUTION: Do not change the IP address for the Ethernet interface that you are

using to communicate with the system. If you change the address, you will lose the

Telnet session.

SNMP

The system supports Simple Network Management Protocol (SNMP),

astandardma

nagement protocol for IP networks. You can configure

the system as an SNMP agent.

As an SNMP agent, the system provides access to management information

that it maintains. See JUNOSe System Basics Configuration Guide, Chapter 4,

Antistatic bags (or other protective packaging to hold components)

Plastic boots or other protective cover for fiber-optic SC and LC connectors

Required Tools and Items 85

ERX 8.0.x Hardware Guide

Storing Modules and Components

Retain the packaging in which a module or component was shipped, and use this

packaging to store the item. Modules are shipped in antistatic bags and protective

packaging. Components, such as transceivers and nonvolatile storage (NVS) cards,

are shipped in antistatic plastic containers within an antistatic padded box.

CAUTION: Failure to store electronic modules and components correctly can

lead to damage of these items.

Follow these guidelines for storing modules and components:

Store each module in a separate antistatic bag.

Store components in an antistatic plastic container. Some of these containers

can accommodate several components in separate compartments.

Do not store multiple modules or components in an antistatic bag or container

where they can touch other items.

(Optional) Store the item in its antistatic bag or container within the protective

packaging or padded box that the item was shipped in.

Cleaning the System

Dust is attracted to the side of the system on which the air intake vent is located.

Clean this side of the system with a dry cloth every few weeks to prevent

excessive accumulation of dust. This cleaning helps to maintain the efficiency of

the cooling system and prevent damage to electronic components.

WARNING: Do not insert any metal object, such as a screwdriver, or place your

hand into an open slot or the backplane when the router 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.

86 Cleaning the System

Maintaining ERX Routers

Upgrading from Release 5.1.1 or Lower-Numbered Releases to Release 6.x.x

or Higher-Numbered Releases

Release 5.1.1 or lower-numbered releases support application images only up to

172 MB. To install larger application images for Release 6.0.0 and higher-numbered

releases, you must first install Release 5.1.2 (or a higher-numbered 5.x.x release).

This enables the system to support application images greater than 172 MB. For

example, you cannot go from Release 5.1.1 to Release 7.2.0 without first upgrading

to Release 5.1.2. See the following table for compatibility of releases.

Your software upgrades may be available remotely through Telnet or FTP, or may

be delivered on a new NVS card. Depending on how you access the software

updates, there are two different procedures to follow. For more detailed information

on installing software, and about NVS cards and SRP modules, see:

JUNOSe System Basics Configuration Guide, Chapter 6, Managing Modules

“Upgrading NVS Cards on SRP Modules” on page 87

Upgrading NVS Cards on SRP Modules

This section describes how to install higher-capacity NVS cards on SRP modules.

The procedure you use depends on the number of SRP modules in the system.

A new NVS card already contains the software release you ordered.

NOTE: The new NVS card must contain the same software release that you are

running on the system.

Upgrading a System That Contains One SRP Module

If the system contains only one SRP module, you must power down the

system before you upgrade the NVS card.

Upgrading NVS Cards on SRP Modules 87

ERX 8.0.x Hardware Guide

CAUTION: Ifyoudonotusethehalt command before removing or powering down

an SRP module, the system’s NVS card can become corrupted.

To upgrade the NVS card on a system that contains one SRP module:

1. Enter the halt command.

See JUNOSe System Basics Configuration Guide, Chapter 6, Managing Modules for

information about the halt command.

WARNING: Do not insert any metal object, such as a screwdriver, or place your

hand into an open slot or the backplane when the router 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 handling modules, use an antistatic wrist strap connected to the

router’s ESD grounding jack. This action helps to protect the module from damage

by electrostatic discharge.

2. Connect the antistatic wrist strap to the ESD grounding jack on the router.

3. Power down the system.

4. Remove the SRP module.

5. Replace the NVS card on the SRP module. (See “Replacing an NVS Card” on

page 89.)

6. Power up the system. (See “Powering Up ERX Routers” on page 73.)

Upgrading a System That Contains Two SRP Modules

In a system that contains two SRP modules, you can upgrade the NVS cards

on the SRP modules without powering down 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 router 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.

88 Upgrading NVS Cards on SRP Modules

Maintaining ERX Routers

CAUTION: When handling modules, use an antistatic wrist strap connected to the

router’s ESD grounding jack. This action helps to protect the module from damage

by electrostatic discharge.

5. Insert the new NVS card into the slot, and push it until it clicks into place.

6. Replace the faceplate on the NVS card slot.

Upgrading Memory on SRP Modules

This section describes how to upgrade memory on SRP modules. JUNOSe

software releases 3.0.x and higher require at least 512 MB of memory on

each SRP module, while releases 5.3.x and higher require at least 1 GB of

memory. See the ERX Module Guide for more information.

NOTE: The ERX-310 SRP module contains two small outline dual inline memory

module (SODIMM) banks that use 256-MB memory, and currently is not

upgradeable.

90 Upgrading Memory on SRP Modules

Maintaining ERX Routers

Four main steps are involved in upgrading memory on SRP modules:

1. Display how much memory is currently installed on the SRP module.

2. Remove the SRP module and the SODIMMs.

3. Add the new SODIMMs to the SRP module.

4. Reinstall the SRP module and verify the upgrade.

See the following sections for information on each step.

WARNING: Do not insert any metal object, such as a screwdriver, or place your

hand into an open slot or the backplane when the router 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 handling modules, use an antistatic wrist strap connected to the

router’s ESD grounding jack, and hold modules by their edges. Do not touch the

components, pins, leads, or solder connections. These actions help to protect

modules from damage by electrostatic discharge.

Displaying the Memory Installed

Before you install the new memory, issue the show hardware command

to see how much memory is installed. Each ERX-7xx and ERX-14xx

model SRP module usually has at least 256 MB of memory. You need one

upgrade kit for each SRP module in the system.

Depending on the upgrade you are performing, the kit contains a

specific number of SODIMMs.

Removing SODIMMs

After removing the SRP module from the router, you might have to remove

lower-memory SODIMMs to upgrade to a higher-capacity SRP module. The

SODIMM sockets are close to the NVS card and have a cream-colored ceramic

connector at one edge. Some or all of the sockets might already contain SODIMMs.

1. PushdownonthebackedgeofaSODIMMtoreleaseitfromthesocket.

(See Figure 38.)

2. Gently pull the SODIMM up and out to disconnect it from the connectors and

remove it from the socket.

2. Insert a SODIMM from the upgrade kit at an angle of approximately 45 degrees

into an empty ceramic connector, so that the notch in the long gold edge of the

SODIMM aligns with the notch in the connector.

The notch on the long gold edge is no longer visible when the SODIMM

is pressed in far enough.

3. Press the top surface downward into the socket until the socket spring snaps

into place and holds it.

4. Repeat Steps 2–3 with the other SODIMM.

5. Repeat Steps 1–4 for the other SRP module, if present.

Verifying the Upgrade

To verify that the upgrade is complete:

1. Place the SRP modules in the chassis.

The SRP modules reboot.

2. Close the ejector handles and tighten the thumbscrews.

3. Issue the show hardware command, and verify that the display indicates that

the correct amountofmemoryispresent.

Replacing SFPs on I/O Modules

This section describes how to replace small form-factor pluggable transceivers

(SFPs) on modules that support these devices. A range of SFPs that support

different optical modes (multimode and single mode) and cabling distances

is available. You can replace the SFPs without disabling the interfaces

or removing the module from 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 router 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 handling electronic components, use an antistatic wrist strap

connected to the system’s ESD grounding jack, and hold components by their

edges. Do not touch, pins, leads, or solder connections. Store components in

antistatic bags. These actions help to protect modules from damage by electrostatic

discharge.

Removing SFPs

To remove the SFPs:

1. Obtain an antistatic container for the SFPs you plan to remove. (See “Storing

Modules and Components” on page 86.)

2. Put the antistatic wrist strap on your wrist, and connect the strap to the

ESD grounding jack on the system.

3. Disconnect the cables from one of the SFPs on the module.

4. Identify the release mechanism for the SFP.

Different SFPs use different release mechanisms. (See Figure 40.) Possible

release mechanisms include:

Replacing FanTrays

Atrayofcool

ing fans provides forced air cooling for components in the ERX routers.

The fan trays are hot-swappable; you can replace them without powering down

the system. However, if you do not replace the fan tray within approximately 2

minutes, the system enters thermal protection mode. For information about

thermal protection mode, see “Monitoring Temperatures of Modules” on page 113.

You can monitor fan status by observing the LEDs on the SRP module or

on the fan tray behind the faceplate. For complete LED information, see

“UnderstandingStatusLEDstoTroubleshoot”onpage104.

NOTE: On the SRP module, when the LED alternates between OK and FAIL in

10–second intervals, a non-critical fan failure exists. Noncritical warnings are not

indicated on the fan tray LEDs; if the red FAN FAIL LED is illuminated, either a

critical or non-critical failure exists.

CAUTION: If the red 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

Troubleshooting

This chapter explains how you can troubleshoot a specific problem, such as

abnormal LED activity or no system power, when you power up the router. It

contains thefollowingsections:

Diagnosing Problems on page 103

Troubleshooting Power Failures on page 104

Understanding Status LEDs to Troubleshoot on page 104

Monitoring Temperatures of Modules on page 113

Resetting Line Modules and SRP Modules on page 114

Double-Bit Errors on SRP Modules on page 114

Diagnosing Problems

When you first encounter a system problem:

1. Make sure power connections are securely attached.

2. Observe the system’s LEDs carefully.

3. Make sure cable connections on the system modules are securely attached.

If a problem is beyond the scope of this chapter, see “Contacting Customer

Support and Returning Hardware” on page 151 for further instructions.

NOTE: Running the show version and show hardware commands is often a good

first step when trying to troubleshoot a problem.

Initialization Sequence

Each line module is initialized independently. As a result, the command-line

interface (CLI) on the SRP module can become available before the line

modules have completed initialization. Commands relating to a line module

Diagnosing Problems 103

ERX 8.0.x Hardware Guide

might fail if the module has not completed initialization. Use the show

version command to display line module status. Do not enter commands

for a line module until its state is listed as 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 “System Specifications” on

page 119 for specifications of power consumption and heat dissipation. If

you suspect a power problem, see Table 10.

Table 10: Causes of Power Failures

Symptom Possible Problems Actions

System does not power up. System is not receiving power.

Module’s power supply has

malfunctioned.

Power source cannot handle

system load.

The following actions apply to all of the

possible problems:

1. Verify that all power connections

are correct.

2. Verify that the power supply is

delivering the correct voltage,

current, and wattage to the system.

See “System Specifications” on

page 119.

3. If the system still does not

operate, contact Juniper Networks

Customer Service.

System shuts down. Temperature is too high.

Power is lost.

The following actions apply to all of the

possible problems:

1. Verify that power connections are

properly attached.

2. Verify that system is receiving

104 Understanding Status LEDs to Troubleshoot

Troubleshooting

familiarize yourself with LED activity so that you can easily detect and correct

a module-related problem with minimal or no system downtime.

LED Identification

The system’s modules have two sets of status LEDs. The top set indicates

overall router and module status. The bottom set indicates module-specific

status, such as port status (line modules) or fan status (SRP module).

The number next to 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 set of port

status LEDs is active during OC12/STM4 operation.

Table 11 presents the functions of the module LEDs and port status LEDs.

Troubleshooting

Redundancy Status

You can determine the redundancy state of line modules by examining the ONLINE

and REDUNDANT status LEDs (ERX-7xx and ERX-14xx models only). See Table 14.

NOTE: The REDUNDANT LED on the cOCx/STMx, FE-8, GE/FE, HSSI, and

OCx/STMx modules is nonfunctional.

Off Off Module is booting or is an

inactive primary line module.

On Off Module is active, but no

standby module is available.

Off On Module is in standby state.

On On Module is active, and a

standby module is available.

Monitoring Temperatures of Modules

You can view the temperature of each module by issuing the show environment all

and show environment table commands. In addition, the system generates detailed

log messages if the temperature of a module is outside normal operating limits.

For example, if the temperature of any forwarding controller exceeds 212° F

(100° C), a message appears on the console and the event is added to the system

log. If you receive this message, report it to your customer service representative.

If the temperature of any module exceeds the upper temperature limit,

the system immediately goes into thermal protection mode. After the

system has entered thermal protection mode, you must resolve the

cause of the high temperature quickly.

Module failure FAIL LED on module is illuminated. Replace module. (See “Installing

Modules” on page 35.)

When you have resolved the cause of the high temperature, you must

power cycle the system to reset the modules.

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 module reset button to reset the module. See Figure 9.

If a line module fails to respond for an extended time, that module might

haveasoftw

are problem. You can depress the software reset button with a

paper clip to suspend the current software task. Depending on the situation,

this action might also reset the software on the module.

If depressing the software reset button fails to correct the issue with the line

module, depress the module reset button to reboot the line module.

The buttons work in the same way for the SRP module. Depressing the

module reset button on an SRP module is equivalent to rebooting the

router 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:

114 Double-Bit Errors on SRP Modules

Troubleshooting

ALERT 05/10/2000 13:10:33 os: failed: ECC DOUBLE BIT ERROR OCCURRED

Address = 0xe95db10

Data (Upper 32Bits) = 0xe95db20

Data (Lower 32Bits) = 0x55d06c

ECC Data Bits = 0x2b

ECC 1Bit Error Counter = 0x0

*** YOU MUST PERFORM A HARD RESET TO CONTINUE ***

ALERT 05/10/2000 13:10:34 os: PROCESSOR EXCEPTION: 0x200n

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. When 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” on page 115.

Fixing Double-Bit Errors

To fix a double-bit error:

1. Remove the second SRP module, if there is one.

2. Reboot the system with the module reset button on the primary SRP module.

(See Figure 9.)

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,

oriftheFAILL

ED 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.

Your Preinstallation Responsibilities 129

ERX 8.0.x Hardware Guide

Verify the operation of all telephone circuits, digital services, and T1 facilities

required for installation.

Ensure that all IP environment requirements are met, such as IP addresses,

subnet masks, and any specific routing protocol information.

Environmental Requirements

See “System Specifications” on page 119 for complete environmental specifications.

Choose a location for the router that is dry, relatively dust free, well ventilated, and

air conditioned. If you install equipment in a rack, be sure that the floor is capable

of supporting the combined weight of the rack and the installed equipment. Place

the router in a location with sufficient access to power and network cables.

Like other network devices, the router generates a significant amount

of heat. You must provide a balanced environment so that the router

performs properly and safely. See “System Specifications” on page 119 for

acceptable ranges of temperature and humidity.

Be sure to allow enough space around the router for adequate ventilation.

Inadequate ventilation can cause the system to overheat.

CAUTION: Do not block the air vents on the routers. Otherwise, the router might

overheat.

Regulatory Compliances

See “System Specifications” on page 119, for a complete list of regulatory

compliance requirements, including safety, EMC, and telecommunications.

Safety Guidelines

For your safety, before installing the system, review all safety warnings in this section.

WARNING: The recommended maximum ambient temperature is 50° C (122° F).

For safe operation, take into consideration the internal temperature of the rack.

WARNING: Install equipment in the rack from the bottom upward. Doing this helps

maintain the stability of the rack and reduces the chance of the rack tipping over.

130 Safety Guidelines

Installation Guidelines and Requirements

WARNING: Do not insert any metal object, such as a screwdriver, into an open slot

or the backplane. Doing so might cause electric shock and serious burns.

WARNING: Three people are required to install the router in a rack: two to lift the

system into position and one to screw it to the rack.

WARNING: Connect the router or rack to ground (earth), and ensure that a reliable

grounding path is maintained in the rack.

WARNING: Do not work on the system or connect or disconnect cables during

lightning activity.

WARNING: Be sure circuit breakers for the power source are in the OFF position

before attaching power cables.

WARNING: Before servicing the router, turn off the power.

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.

CAUTION: Evaluate the overall loading of the branch circuit before you install

any equipment into a rack.

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 52 shows the location of the

serial port and the sequence of the pins in the RS-232 connector.

The console port is considered a data terminal equipment interface

(DTE). Direct connection to a terminal or PC (which also have DTE

interfaces) requires a crossover cable.

Return Procedure 151

ERX 8.0.x Hardware Guide

1. Determine the part number and serial number of the component. For

instructions, see “Locating Component Serial Numbers ” on page 152.

2. Obtain a Return Materials Authorization (RMA) number from the Juniper

Networks Technical Assistance Center (JTAC). See “Information You Might

Need to Supply to JTAC” on page 153.

Provide the following information in your e-mail message or during the

telephone call:

Part number and serial number of component

Your name, organization name, telephone number, and fax number

The shipping address for the replacement component, including contact

name and phone number

Description of the failure

The support representative validates your request and issues an RMA number

for return of the component.

3. Pack the routing node or component for shipment, performing the procedure

described in “Returning Products for Repair or Replacement” on page 154.

Locating Component Serial Numbers

Before contacting Juniper Networks to request a Return Materials Authorization

(RMA), you must find the serial number on the chassis or component. To list all the

chassis modules and their serial numbers, enter the following command:

host1#show hardware

You can also find the serial numbers on the modules. ID stickers are

usually applied near the ejector. See Figure 57.

Fan trays are not listed in the show hardware command output. ERX-7xx model

and ERX-14xx model fan trays have stickers on the faceplate. For the ERX-310

router, you must remove the fan tray to view the serial number ID sticker.

Returning Products for Repair or Replacement

In the event of a hardware failure, please contact Juniper Networks to obtain

a Return Material Authorization (RMA) number. This number is necessary to

ensure proper tracking and handling of returned material at the factory. Do

not return any hardware until you have received an RMA. Juniper Networks

reserves the right to refuse shipments that do not have an RMA. Refused

shipments will be returned to the shipper via collect freight.

See the customer support Web page for complete repair and return

policies and procedures.

Packing Instructions for Returning a Chassis

If possible, use the original shipping crate, pallet, and packing materials in

which the chassis was originally shipped. If these materials are unavailable, use

comparable shipping material, or contact your Juniper Networks representative

for information on approved packaging material.

154 Returning Products for Repair or Replacement
