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 (i) Juniper Networks, Inc. (if the Customer’s principal office is located in the Americas) or Juniper Networks (Cayman) Limited (if the Customer’s principal office is located outside the Americas) (such applicable entity being referred to herein as “Juniper”), and (ii) 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, for which Customer has paid the applicable license or support fees to Juniper or an authorized Juniper reseller, or which was embedded by Juniper in equipment which Customer purchased from Juniper or an authorized Juniper reseller. “Software” also includes updates, upgrades and new releases of such software. “Embedded Software” means Software which Juniper has embedded in or loaded onto the Juniper equipment and any updates, upgrades, additions or replacements which are subsequently embedded in or loaded onto the 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 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 or IMS AAA software on multiple computers or virtual machines (e.g., Solaris zones) requires multiple licenses, regardless of whether such computers or virtualizations 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, ports or transactions, or require the purchase of separate licenses to use particular features, 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) for the Software from Juniper or an authorized Juniper reseller.

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 Embedded Software on non-Juniper equipment; (j) use Embedded Software (or make it available for use) on Juniper equipment that the 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.

■ iii

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 liability set 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 payable under this agreement are exclusive of tax. Customer shall be responsible for paying Taxes arising from the purchase of the license, or importation or use of the Software. If applicable, valid exemption documentation for each taxing jurisdiction shall be provided to Juniper prior to invoicing, and Customer shall promptly notify Juniper if their exemption is revoked or modified. All payments made by Customer shall be net of any applicable withholding tax. Customer will provide reasonable assistance to Juniper in connection with such withholding taxes by promptly: providing Juniper with valid tax receipts and other required documentation showing Customer’s payment of any withholding taxes; completing appropriate applications that would reduce the amount of withholding tax to be paid; and notifying and assisting Juniper in any audit or tax proceeding related to transactions hereunder. Customer shall comply with all applicable tax laws and regulations, and Customer will promptly pay or reimburse Juniper for all costs and damages related to any liability incurred by Juniper as a result of Customer’s non-compliance or delay with its responsibilities herein. Customer’s obligations under this Section shall survive termination or expiration of this Agreement.

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 (“GPL”) or the GNU Library General Public License (“LGPL”)), Juniper will make such source code portions (including Juniper modifications, as appropriate) available upon request for a period of up to three years from the date of distribution. Such request can be made in writing to Juniper Networks, Inc., 1194

N. Mathilda Ave., Sunnyvale, CA 94089, ATTN: General Counsel. You may obtain a copy of the GPL at http://www.gnu.org/licenses/gpl.html, and a 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

iv ■

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 and all related documentation is and will be in the English language)).

■ ERX Modules on page 9

■ Network Management Tools on page 14

■ Redundancy Features on page 14

Overview

ERX routers are modular, carrier-class networking devices that deliver performance, reliability, and service differentiation to both business and consumer Internet users. The ERX7xx and ERX14xx models offer high port density, low power consumption, and fully redundant Internet access routing and edge aggregation. The Juniper Networks ERX310 Broadband Services 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:

■ Juniper Networks ERX1440 Broadband Services Router

■ Juniper Networks ERX1410 Broadband Services Router

■ Juniper Networks ERX710 Broadband Services Router

■ Juniper Networks ERX705 Broadband Services Router

■ Juniper Networks ERX310 Broadband Services Router

All models use the same software. However, the specific model determines the:

■ Combination of line modules supported

■ Conditions for line rate performance of line modules

■ Type, capacity, and number of SRP modules used

ERX 11.1.x Hardware Guide

ERX14xx Models

NOTE: In the E Series documentation, the term ERX14xx models refers to both the ERX1440 and ERX1410 routers. The terms ERX1440 and ERX1410 routers refer to the specific models. See Figure 1 on page 5 and Figure 2 on page 5.

The ERX1440 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 ERX1410 router manages high levels of network traffic, and uses the 10-Gbps SRP module (SRP-10G). You can configure the ERX1410 router 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 the resources available. The former option restricts the allowed combinations of line modules. For information on configuring performance of line modules, see JUNOSe System Basics Configuration Guide, Chapter 6, Managing Modules.

NOTE: The 10-Gbps SRP module used in the ERX310 router is different from the 10-Gbps SRP module used in the ERX1410 router. See “SRP Module” on page 9 for more information.

Externally, the ERX1440 chassis is the same as the ERX1410 chassis. (See Figure 1 on page 5 and Figure 2 on page 5.) Both routers contain 14 vertical slots to accommodate modules.

Internally, the ERX1440 chassis differs from the ERX1410 chassis, and includes a special midplane for the 40-Gbps SRP module.

Installation procedures and operating procedures are identical for both systems. All ERX7xx and ERX14xx 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.

ERX7xx Models

NOTE: In the E Series documentation, the term ERX7xx models refers to both the ERX705 and ERX710 routers. The terms ERX705 and ERX710 routers refer to the specific models. See Figure 3 on page 6 and Figure 4 on page 7.

The ERX7xx models are robust, high-density routers with less capacity than the ERX14xx models. The ERX7xx models use either the SRP-10G module or the SRP-5G module.

You can configure the ERX7xx models to enable the line modules (LM) to operate either at full line rate performance or at a rate dependent on the resources available. For information about configuring performance of line modules, see JUNOSe System Basics Configuration Guide, Chapter 6, Managing Modules.

NOTE: The 10-Gbps SRP module used in the ERX310 router is different from the 10-Gbps SRP module used in the ERX710 router. See “SRP Module” on page 9 for more information.

The ERX705 chassis is the same as the ERX710 chassis. (See Figure 3 on page 6 and Figure 4 on page 7.) The chassis contains seven slots to accommodate modules. Installation procedures and operating procedures are identical for both systems. All ERX7xx and ERX14xx 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.

ERX310 Broadband Services Router

Chapter 1: ERX Overview

The ERX310 router is a low-end platform that supports all of the same services as the ERX7xx and ERX14xx models, but with smaller capacity and scaling capabilities. Like the ERX7xx and ERX14xx models, the ERX310 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 ERX310 router is designed to be used as a small distributed POP router as well as a high-end CPE router.

The ERX310 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 ERX310 router is different from the 10-Gbps SRP module used in the ERX7xx and ERX14xx models. See “SRP Module” on page 9 for more information.

The ERX310 router is available in either redundant AC- or DC-powered models.

ERX Modules

Chapter 1: ERX Overview

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 module connects to a corresponding I/O module via a passive midplane. See Figure 8 on page 9.

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 95.

Figure 8: Modules in ERX14xx Models

SRP Module

NOTE: Some line 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 line module specifications.

Switch route processor (SRP) modules perform system management, routing table calculations and maintenance, forwarding table computations, statistics processing,

Figure 10: SRP Module for ERX310 Router

Chapter 1: ERX Overview

Module Details

ERX7xx and ERX14xx models use up to two redundant SRP modules operating in an active/standby configuration. ERX310 router 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 ERX7xx and ERX14xx models. Only a 10-Gbps SRP module (SRP-SE10G) can be used in ERX310 router. 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 ERX7xx and ERX14xx models cannot be used in the ERX310 router, and vice versa.

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

ERX Modules ■ 11

ERX 11.1.x Hardware Guide

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 31.

SRP Module Redundancy

SRP module redundancy is available only for ERX7xx and ERX14xx models. See “Redundancy Features” on page 14

Nonvolatile Storage

The PCMCIA slot on the front of the SRP module holds a Type II PCMCIA nonvolatile storage (NVS) card. (See Figure 9 on page 10 and Figure 10 on page 11.) This card is loaded with the system's software and configuration files. The PCMCIA card is factory installed.

SRP I/O Module

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.

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 ERX7xx and ERX14xx models cannot be used in the ERX310 router, and vice versa. See Figure 2 on page 5, Figure 4 on page 7, and Figure 6 on page 8 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.

■ 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.

12 ■ ERX Modules

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

and minor router alarms (ERX7xx and ERX14xx models only; 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.

Line Modules

Chapter 1: ERX Overview

BNC connectors and wire wraps are available for ERX7xx and ERX14xx models only.

For details about installing the SRP I/O module, see “Installing Modules” on page 31.

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 on page 13 shows a representative line module. For details about installing line modules, see “Installing Modules” on page 31.

Figure 11: Representative Line Module

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.

ERX Modules ■ 13

ERX 11.1.x Hardware Guide

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 on page 5, Figure 4 on page 7, and Figure 6 on page 8 for locations. For details about installing I/O modules, see “Installing Modules” on page 31.

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 NMC-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 ERX7xx and ERX14xx models only. ERX310 routers contain one SRP module and therefore do not offer SRP module redundancy.

14 ■ Network Management Tools

Chapter 1: ERX Overview

ERX7xx and ERX14xx 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.

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 “Installing Modules” on page 31.

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 31.

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 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.

Redundancy Features ■ 15

ERX 11.1.x Hardware Guide

Line Modules

NOTE: This section applies to ERX7xx and ERX14xx models only. ERX310 routers do not offer line module redundancy.

ERX7xx and ERX14xx 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 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 can cover 3–6 slots. It provides additional connectivity that enables the spare line module to take 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:

1. Breaks the connection between the primary I/O module and the primary line

module.

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.

Figure 12 on page 17 shows the data flow when a spare line module becomes active.

Chapter 1: ERX Overview

Power

Fans

For information about installing modules for line module redundancy, see “Installing Modules” on page 31. For information about configuring and managing SRP module redundancy, see JUNOSe System Basics Configuration Guide, Chapter 6, Managing Modules.

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 ERX310 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 on page 8 and Figure 6 on page 8.) The power supplies convert AC power to internal –48 V redundant DC feeds that are then distributed through the router.

Forced air-cooling keeps the temperature of the E Series modules and components within normal operating limits. In ERX14xx models, six cooling fans are located in a tray at the top of the router (Figure 1 on page 5). In ERX7xx models, four cooling fans are located in a tray on one side of the router (Figure 3 on page 6). In the

Redundancy Features ■ 17

ERX 11.1.x Hardware Guide

ERX310 router, two cooling fans are located in a tray on one side of the router (Figure 5 on page 8).

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 95.

In ERX7xx and ERX14xx models, the fan tray has two redundant converters that power the fans (for the ERX14xx models, a –24 V, 50 W converter; for the ERX7xx models, a –12 V, 15 W converter). If one converter fails, the other takes over. The ERX310 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.

Installing ERX Routers

This chapter describes how to install ERX routers in a rack. It contains the following sections:

■ Before You Begin on page 25

■ Freestanding Installation on page 25

■ Rack-Mounted Installation on page 26

■ The Next Step on page 29

Before You Begin

Before installing E Series routers, be sure you:

■ Have a plan for installing the routers that takes into consideration future

expansion of your system.

■ Have the tools and accessories needed to complete the installation.

■ Read and understand the clearance requirements for the front and back of the

chassis for cable routing and other unit access. See “Environmental Requirements” on page 117 for more information.

■ Read and understand the clearance requirements for the chassis to ensure

adequate ventilation.

■ Prepare the equipment racks by measuring and marking space for each router

and plenum you plan to install.

Freestanding Installation

When installing the system on a table top or in any other freestanding mode, be sure to leave enough space around the system for adequate ventilation. Position the router with easy access to the connections that it needs for power, local communications, and remote communications.

See “Installation Guidelines and Requirements” on page 117, and “System Specifications” on page 109, for more information.

WARNING: Two people are required to lift an E Series router.

Before You Begin ■ 25

ERX 11.1.x Hardware Guide

CAUTION: To prevent electrostatic damage to the system and its components, make sure persons handling the router wear an antistatic device.

Connectors are located on the I/O modules and the power input module. These modules are installed from the rear of the router. (See Figure 14 on page 26.) See “Cabling ERX Routers” on page 47 for cabling installation procedures.

Figure 14: ERX7xx Models, Rear View

Rack-Mounted Installation

We recommend that you use a standard EIA distribution rack. See “Equipment Rack Requirements” on page 121 for detailed rack information.

Installation Guidelines

Before installing the systems in a rack, consider the following guidelines and refer to Figure 15 on page 27:

■ You can install up to 3 ERX14xx models, 6 ERX7xx models, or 14 ERX310 routers

in a single 7-ft. (2.1 m) rack.

Installing multiple systems in a single rack enables you to maximize your available space.

■ You can install an ERX14xx model, an ERX7xx model, and an ERX310 router

together in the same rack. (See Figure 15 on page 27.)

CAUTION: If you install an ERX7xx model or ERX310 router directly above an ERX14xx model in the same rack, you must install a plenum between the ERX7xx model or ERX310 router and the ERX14xx model so that the air can circulate between the systems. (See Figure 53 on page 124.) This plenum is available from Juniper Networks.

26 ■ Rack-Mounted Installation

Chapter 3: Installing ERX Routers

If you install an ERX14xx model above an ERX7xx model or ERX310 router, there is no need to install a plenum between the units because the ERX7xx models and ERX310 routers vent air out the side of the chassis.

■ Install heavier systems, such as an ERX14xx model, on the bottom of the rack.

Mount lighter systems, such as the ERX310 router, higher in the rack.

Figure 15: ERX Routers Installed in Recommended Order

Safety Guidelines

Observe the following safety guidelines when mounting the router in a rack.

WARNING: Install equipment in the rack from the bottom upward. This helps to maintain the stability of the rack and reduces the chance of the rack tipping over.

Rack-Mounted Installation ■ 27

ERX 11.1.x Hardware Guide

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: Evaluate the overall loading of the branch circuit before you install any equipment into a 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.

WARNING: Do not insert any metal object, such as a screwdriver, into an open slot or the backplane. Doing so can cause electric shock and serious burns.

WARNING: The ERX310 router AC model has more than one power-supply cord. Disconnect two power cords before servicing to avoid electric shock.

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.

Chapter 3: Installing ERX Routers

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

■ A No. 2 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.

The Next Step

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 47 for

instructions on installing the cables.)

OC48 Line Modules

GE-2 Line Modules

The ERX1440 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 ERX1440 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.

The ERX1440 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 ERX310 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 to add or remove a module without powering down the system.

Protecting Modules and Slots

Each ERX chassis has an ESD (electrostatic discharge) grounding jack. See Table 3 on page 35 for locations. To prevent damage from electrostatic discharge, connect an antistatic wrist strap to the jack when handling components.

34 ■ Overview

Chapter 4: Installing Modules

To protect the modules and slots when installing modules, observe the following guidelines:

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.

CAUTION: Always handle the module by its edges. Do not touch the components, pins, leads, or solder connections.

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.

Overview ■ 35

ERX 11.1.x Hardware Guide

Order of Installation

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.

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.

Required Tools and Safety Items

You need the following tools to install a line module:

■ A No. 2 Phillips screwdriver

■ An ESD wrist strap

Safety Guidelines

Before and during the installation process, observe the following precautions:

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: 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.

36 ■ Safety Guidelines

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

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

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.

Installing Components for Line Module Redundancy

A spare line module provides redundancy for a group of identical line modules for ERX7xx and ERX14xx models only.

42 ■ Installing Components for Line Module Redundancy

Chapter 4: Installing Modules

NOTE: The ERX310 router does not support line module redundancy.

For line module redundancy to operate, you must install:

■ The line modules, including the spare line module

■ The redundancy midplane

■ The I/O modules, including the spare I/O module

For more information, see “Redundancy Features” on page 14.

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 can 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.

Installing the Line Modules

To install the line modules in a redundancy group:

1. Install the spare line module in the lowest-numbered slot of the redundancy

group.

2. Install the other line modules in the remaining slots. (See “Installing Line and

I/O Modules” on page 40.)

Port and Cable UsedConnection

Management connection between SRP I/O module and the LAN

Management connection between SRP I/O module and a management console

Direct connections to I/O modules

NOTE: If you plan to use a cable-management bracket (ERX7xx and ERX14xx 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 ERX7xx Models” on page 92.

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).

One 10/100Base-T Ethernet management port with an RJ-45 connector

One RS-232 port with a DB-9 connector for VT100 management access

See the ERX Module Guide for specific I/O module connector information

When connecting a console directly to the 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. See Figure 24 on page 51 and Figure 25 on page 52.

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.

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.

Cabling the SRP I/O Module ■ 51

ERX 11.1.x Hardware Guide

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 on page 51 and Figure 25 on page 52.)

■ 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.

Figure 25: SRP I/O Module for the ERX310 Router

See “Accessing ERX Routers” on page 69 for more information about management access.

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-band connection.

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.

52 ■ Cabling the SRP I/O Module

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

1. Insert the female DB-9 connector into the RS-232 port, and tighten the screws.

CAUTION: Do not overtighten the screws.

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.

Chapter 5: Cabling ERX Routers

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.

Task 1: Turn Off All Router Power

Before starting, you must switch all router power switches to OFF.

To turn off the router, push each power switch to the OFF position.

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:

Cabling the Router for Power ■ 55

ERX 11.1.x Hardware Guide

1. Locate the grounding studs on the router (Figure 26 on page 55 and Figure 27

on page 57).

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 on page 55, Figure 27 on page 57, and Figure 28 on page 58 as needed.

For specifications on the electrical requirements for the system, see “System Specifications” on page 109. For details on the power consumed by the different ERX modules, see the ERX Module Guide.

NOTE: In this procedure, we assume that the system is already connected to a power source. See “Cabling ERX Routers” on page 47.

Before You Power Up the System ■ 65

ERX 11.1.x Hardware Guide

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 power switches to ON.

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

booting properly. See Table 11 on page 101 in “Troubleshooting” on page 95 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:

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

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.

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.

host1>

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.

66 ■ Status LEDs

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 95 for information on the system's LEDs.

Powering Down

The Next Step

Chapter 6: Powering Up ERX Routers

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: If you do not use the halt 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.

If you have problems powering up the system, see “Troubleshooting” on page 95 for help.

If the system boots properly, see “Accessing ERX Routers” on page 69.

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 69

■ Console Port Setup on page 69

■ Telnet Setup on page 72

■ SNMP on page 73

■ The Next Step on page 73

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 52.) You use the console to communicate with the system during the power-up process, set an IP address, and manage the system using the command-line interface (CLI).

Console Port Setup

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).

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.

Setting Up Management Access ■ 69

ERX 11.1.x Hardware Guide

Using HyperTerminal

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.

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) in the Name field.

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 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.

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.

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 36 on page 71.

70 ■ Console Port Setup

Figure 36: Management Ports for ERX Routers

ERX310 router

ERX14xx models

ERX7xx models

Chapter 7: Accessing ERX Routers

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

3. Power up the system.

NOTE: Direct access through the RS-232 serial port enables you to monitor the system while it boots.

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 65.) 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.

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 System Basics Configuration Guide.

host1>enable host1#

The system is now in Privileged Exec mode.

2. Set an IP address 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).

Console Port Setup ■ 71

ERX 11.1.x Hardware Guide

Telnet Setup

■ Use an IP address valid for the system.

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 72.

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.

2. Enter the configure command.

host1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. host1(config)#

The system is now in Global Configuration mode.

3. Enter the line command.

host1(config)#line vty 0 4 host1(config-line)#

72 ■ Telnet Setup

The system is now in Line Configuration mode.

4. Disable the password.

host1(config-line)#no login

Chapter 7: Accessing ERX Routers

NOTE: In this example, you disabled the password requirement, but you can choose to set a password instead. See JUNOSe System Basics Configuration Guide, Chapter 8, Passwords and Security for information on setting a password.

5. Run Telnet from a host on the same Ethernet network as the system.

6. Enter the IP address of the system to open the Telnet session.

The User Exec prompt appears when the Telnet session to the system is established.

host1>

7. Enter the enable command.

host1>enable host1#

SNMP

The system is now in Privileged Exec mode.

8. Enter the configure command.

host1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. host1(config)#

The system is now in Global Configuration mode, from which you can configure the system. See JUNOSe System Basics Configuration Guide, Chapter 2, Command-Line Interface.

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.

The system supports Simple Network Management Protocol (SNMP), a standard management 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, Configuring

SNMP for information on SNMP. See JUNOSe Command Reference Guide A to M and JUNOSe Command Reference Guide N to Z for the commands that are available for

configuring the system as an SNMP agent.

Required Tools and Items ■ 77

ERX 11.1.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

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

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.

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.

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).

78 ■ Storing Modules and Components

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.

5.1.1 or lower-numbered release

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:

■ Upgrading NVS Cards on SRP Modules on page 79

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.

CAUTION: If you do not use the halt 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:

Upgrading NVS Cards on SRP Modules ■ 79

ERX 11.1.x Hardware Guide

1. Enter the halt command.

See JUNOSe System Basics Configuration Guide, Chapter 6, Managing Modules for information about the halt command.

7. 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 ERX310 SRP module contains two small outline dual inline memory module (SODIMM) banks that use 256-MB memory, and currently is not upgradeable.

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.

82 ■ Upgrading Memory on SRP Modules

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 ERX7xx and ERX14xx 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

Chapter 8: Maintaining ERX Routers

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. Push down on the back edge of a SODIMM to release it from the socket. (See

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

remove it from the socket.

ERX 11.1.x Hardware Guide

1. Locate the four SODIMM sockets on the SRP module. (See Figure 38 on page 84

and Figure 39 on page 84.) See the previous section to learn how to remove SODIMMs.

Figure 39: SODIMM Sockets on the SRP-40 Module

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.
