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 Overview

This chapter provides introductory information about the ERX routers. It contains the following sections:

■ Overview on page 3

■ ERX Routers on page 3

■ 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,

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 on page 10 and Figure 10 on page 11.)

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.
