End User License Agreement

READ THIS END USER LICENSE AGREEMENT (“AGREEMENT”) BEFORE DOWNLOADING, INSTALLING, OR USING THE SOFTWARE. BY DOWNLOADING, INSTALLING, OR USING THE SOFTWARE OR OTHERWISE EXPRESSING YOUR AGREEMENT TO THE TERMS CONTAINED HEREIN, YOU (AS CUSTOMER OR IF YOU ARE NOT THE CUSTOMER, AS A REPRESENTATIVE/AGENT AUTHORIZED TO BIND THE CUSTOMER) CONSENT TO BE BOUND BY THIS AGREEMENT. IF YOU DO NOT OR CANNOT AGREE TO THE TERMS CONTAINED HEREIN, THEN (A) DO NOT DOWNLOAD, INSTALL, OR USE THE SOFTWARE, AND (B) YOU MAY CONTACT JUNIPER NETWORKS REGARDING LICENSE TERMS.

1. The Parties. The parties to this Agreement are Juniper Networks, Inc. and its subsidiaries (collectively “Juniper”), and the person or organization that originally purchased from Juniper or an authorized Juniper reseller the applicable license(s) for use of the Software (“Customer”) (collectively, the “Parties”).

2. The Software. In this Agreement, “Software” means the program modules and features of the Juniper or Juniper-supplied software, and updates and releases of such software, for which Customer has paid the applicable license or support fees to Juniper or an authorized Juniper reseller. “Embedded Software” means Software which Juniper has embedded in the Juniper equipment.

3. License Grant. Subject to payment of the applicable fees and the limitations and restrictions set forth herein, Juniper grants to Customer a non-exclusive and non-transferable license, without right to sublicense, to use the Software, in executable form only, subject to the following use restrictions:

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

b. Customer shall use the Software on a single hardware chassis having a single processing unit, or as many chassis or processing units for which Customer has paid the applicable license fees; provided, however, with respect to the Steel-Belted Radius or Odyssey Access Client software only, Customer shall use such Software on a single computer containing a single physical random access memory space and containing any number of processors. Use of the Steel-Belted Radius software on multiple computers requires multiple licenses, regardless of whether such computers are physically contained on a single chassis.

c. Product purchase documents, paper or electronic user documentation, and/or the particular licenses purchased by Customer may specify limits to Customer’s use of the Software. Such limits may restrict use to a maximum number of seats, registered endpoints, concurrent users, sessions, calls, connections, subscribers, clusters, nodes, realms, devices, links, 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 the Embedded Software on non-Juniper equipment; (j) use the 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.

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 for the Software are exclusive of taxes, withholdings, duties, or levies (collectively “Taxes”). Customer shall be responsible for paying Taxes arising from the purchase of the license, or importation or use of the Software.

11. Export. Customer agrees to comply with all applicable export laws and restrictions and regulations of any United States and any applicable foreign agency or authority, and not to export or re-export the Software or any direct product thereof in violation of any such restrictions, laws or regulations, or without all necessary approvals. Customer shall be liable for any such violations. The version of the Software supplied to Customer may contain encryption or other capabilities restricting Customer’s ability to export the Software without an export license.

12. Commercial Computer Software. The Software is “commercial computer software” and is provided with restricted rights. Use, duplication, or disclosure by the United States government is subject to restrictions set forth in this Agreement and as provided in DFARS 227.7201 through 227.7202-4, FAR 12.212, FAR 27.405(b)(2), FAR 52.227-19, or FAR 52.227-14(ALT III) as applicable.

13. Interface Information. To the extent required by applicable law, and at Customer's written request, Juniper shall provide Customer with the interface information needed to achieve interoperability between the Software and another independently created program, on payment of applicable fee, if any. Customer shall observe strict obligations of confidentiality with respect to such information and shall use such information in compliance with any applicable terms and conditions upon which Juniper makes such information available.

14. Third Party Software. Any licensor of Juniper whose software is embedded in the Software and any supplier of Juniper whose products or technology are embedded in (or services are accessed by) the Software shall be a third party beneficiary with respect to this Agreement, and such licensor or vendor shall have the right to enforce this Agreement in its own name as if it were Juniper. In addition, certain third party software may be provided with the Software and is subject to the accompanying license(s), if any, of its respective owner(s). To the extent portions of the Software are distributed under and subject to open source licenses obligating Juniper to make the source code for such portions publicly available (such as the GNU General Public License (“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 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)).

Overview of Services Routers

J-series Services Routers running JUNOS software with enhanced services provide stable, reliable, and efficient IP routing, WAN and LAN connectivity, and management services for small to medium-sized enterprise networks. These routers also provide network security features, including a stateful firewall with access control policies and screens to protect against attacks and intrusions, and IPSec VPNs. J-series Services Routers securely connect small, branch, and regional offices to a central site router across Internet service provider (ISP) networks.

J-series Services Routers run JUNOS software with enhanced services, which offers many advanced routing and security services.

You can use two user interfaces to monitor, configure, troubleshoot, and manage a Services Router:

■ J-Web interface—A Web-based graphical interface that allows you to operate a

router without commands. The J-Web interface provides access to all JUNOS functionality and features. Quick Configuration wizards simplify basic configuration and minimize the risk of operator error.

■ JUNOS command-line interface—A Juniper Networks command shell that runs

on top of a UNIX-based operating system kernel. The CLI is a straightforward command interface. On a single line, you type commands that are executed when you press the Enter key. The CLI provides command Help and command completion.

For an introduction to the J-Web and CLI interfaces, see the JUNOS Software Administration Guide. For more information, see the J-Web Interface User Guide and the JUNOS CLI User Guide

JUNOS Software with Enhanced Services Hardware Guide

J2320 and J2350 Chassis

The J2320 and J2350 chassis is a rigid sheet metal structure that houses all the other router components (see Figure 1 on page 8 through Figure 7 on page 11). The chassis can be installed in many types of racks or cabinets. For information about acceptable rack types, see “Rack Requirements” on page 64.

In addition to the components described in subsequent sections, the chassis includes the following components:

■ Mounting brackets—One pair of metal brackets can be mounted at the front or

center of the chassis for mounting the chassis in a rack or cabinet.

■ Earthing terminal—A protective earthing terminal and a PEM nut at the rear of

the chassis ensure safe dissipation of static electricity in all situations.

■ ESD point—One electrostatic discharge (ESD) point, a banana plug receptacle at

the front of the chassis, minimizes the risk of electrical discharge in potentially hazardous environments.

CAUTION: Before removing or installing components of a functioning router, attach an ESD strap to an ESD point and place the other end of the strap around your bare wrist. Failure to use an ESD strap could result in damage to the router.

The router must be connected to earth ground during normal operation. The protective earthing terminal on the rear of the chassis is provided to connect the router to ground (see Figure 3 on page 9). Additional grounding is provided to an AC-powered router when you plug its power supply into a grounded AC power receptacle.

For additional safety information, see “Safety and Regulatory Compliance Information” on page 197.

JUNOS Software with Enhanced Services Hardware Guide

J2320 and J2350 Midplane

The J2320 and J2350 midplane is located in the center of the chassis and forms the rear of the PIM card cage (see Figure 6 on page 10 and Figure 7 on page 11). You install the PIMs into the midplane from the front of the chassis. Data packets are transferred across the midplane from the PIM to the Routing Engine, and from the Routing Engine across the midplane to the destination PIM.

J2320 and J2350 Routing Engine Hardware

The Routing Engine consists of the following components:

■ Processor—Creates the packet forwarding switch fabric for the router and runs

JUNOS software to maintain the router's routing tables and routing protocols.

■ DRAM—Buffers incoming packets and provides storage for the routing and

forwarding tables and for other Routing Engine processes.

To view the amount of DRAM installed on your router, issue the show chassis

routing-engine command.

■ EPROM—Stores the serial number of the Routing Engine.

To view the serial number of the Routing Engine, issue either the show chassis

routing-engine command or the show chassis hardware command.

■ Crypto Accelerator Module—Processor card that enhances performance of

cryptographic algorithms used in IP security (IPSec) services. The cryptographic algorithms supported include Advanced Encryption Standard (AES), Data Encryption Standard (DES), triple DES (3DES), Hashed Message Authentication Code-Message Digest 5 (HMAC-MD5), and HMAC-Secure Hash Algorithm 1 (SHA-1). The Crypto Module is an optional feature of J2320 and J2350 Services Routers.

To determine whether there is a Crypto Accelerator Module installed on your router, issue the show chassis hardware command.

■ Compact flash—Provides primary storage for software images, configuration

files, and microcode. J-series routers have a primary or internal compact flash located on the system board. For information about replacing the internal compact flash, see “Replacing Internal Compact Flashes on J2320 and J2350 Routers” on page 126.

J2320 and J2350 Services Routers also provide a slot in the rear of the chassis into which you can insert an additional external compact flash. For information about external compact flashes, see “J2320 and J2350 External Compact Flashes” on page 18.

J2320 and J2350 Boot Devices

J2320 and J2350 Services Routers can boot from three devices:

■ Internal compact flash

■ External compact flash (also known as the removable compact flash)

12 ■ J2320 and J2350 Services Router Hardware Features

■ USB storage device

Normally, a J2320 or J2350 Services Router boots from the internal compact flash. If the internal compact flash fails, the router attempts to boot from the external compact flash if it is installed. If the external compact flash is not present or fails, the router attempts to boot from the USB storage device.

When a USB storage device is installed and configured, it automatically acts as a secondary boot device if the internal compact flash fails on startup. Depending on the size of the USB storage device, you can also configure it

J2320 and J2350 Services Router Hardware Features ■ 17

JUNOS Software with Enhanced Services Hardware Guide

to receive any core files generated during a failure. For information about configuring a USB storage device, see the JUNOS Software Administration Guide.

NOTE: For a list of supported USB storage devices, see the JUNOS Software with Enhanced Services Release Notes at http://www.juniper.net.

J2320 and J2350 External Compact Flashes

On J2320 and J2350 routers, an external compact flash, also known as removable compact flash, accepts a type I or II compact flash, as defined in the CompactFlash Specification published by the CompactFlash Association. The J2320 and J2350 chassis has a slot on the rear for external compact flashes (see Figure 3 on page 9). When the external compact flash is installed and configured, it automatically acts as the secondary boot device if the internal compact flash fails on startup.

Depending on the capacity of the external compact flash, you can also configure it to receive any core files generated during a failure. For information about configuring an external compact flash, see the JUNOS Software Administration Guide.

J2320 Power System

J2350 Power System

The J2320 Services Router uses AC power (see Figure 3 on page 9). The autosensing power supply distributes the different output voltages to the router components according to their voltage requirements. The power supply is fixed in the chassis, and is not field-replaceable.

The AC power supply has a single AC appliance inlet that requires a dedicated AC power feed.

The J2320 AC-powered chassis has a power switch and does not include a power LED.

For information about site power preparations, see “Power Guidelines, Requirements, and Specifications” on page 67. For information about connecting the router to power and ground, see “Connecting Power” on page 84.

The J2350 Services Router uses either AC or DC power. The autosensing power supply (see Figure 4 on page 9 or Figure 5 on page 10) distributes the different output voltages to the router components according to their voltage requirements. The power supply is fixed in the chassis, and is not field-replaceable.

The AC power supply has a single AC appliance inlet that requires a dedicated AC power feed. The DC power supply has a terminal block that provides a single DC input (–48 VDC and return) and requires a dedicated 15 A (–48 VDC) circuit breaker.

The J2350 AC-powered or DC-powered chassis has a power switch and does not include a power LED.

18 ■ J2320 and J2350 Services Router Hardware Features

NOTE: You cannot mix DC and AC power supplies in the same chassis.

WARNING: DC-powered Services Routers are intended for installation only in a

restricted access location.

J2320 and J2350 Cooling System

The cooling system in J2320 and J2350 routers is from side to side. The J2320 router has five cooling fans and the J2350 router has four cooling fans. The fans draw air through vents along the left side of the chassis and exhaust it through vents on the right side of the chassis. The airflow produced by these fans keeps router components within the acceptable temperature range (see Figure 11 on page 20 and Figure 12 on page 20). The speed of the fans is adjusted automatically according to the current temperature.

Chapter 2: J-series Services Router Hardware Features

On J2350 routers that comply with Network Equipment Building System (NEBS) criteria, an air filter protects the air intake opening at the front of the chassis and must be replaced periodically. To verify that the system is a NEBS-compliant system, run the show chassis hardware command. A NEBS-compliant system displays the term NEBS in the output. For instructions on how to replace air filters, see “Replacing Air Filters on J2350 Routers” on page 153.

The Routing Engine monitors the temperature of the router components. If the maximum temperature specification, as measured at the CPU junction, is exceeded and the router cannot be adequately cooled, the Routing Engine shuts down the hardware components.

J2320 and J2350 routers shut down when the CPU temperature reaches 80°C (176°F). There is no alarm for temperature. You can view the CPU junction temperature using the show chassis routing-engine command. The CPU temperature runs a few degrees higher than the routing engine temperature displayed on the Monitor>Chassis page of the J-Web interface.

An additional fan is part of each power supply. This fan is not regulated by the operating system.

J4350 and J6350 Chassis

The J4350 and J6350 chassis is a rigid sheet metal structure that houses all the other router components (see Figure 13 on page 22 through Figure 18 on page 24). The chassis can be installed in many types of racks or cabinets. For information about acceptable rack types, see “Rack Requirements” on page 64.

In addition to the features described in subsequent sections, the chassis includes the following features:

■ Mounting brackets—One pair of metal brackets can be mounted at the front or

center of the chassis. Use the brackets for mounting the chassis in a rack or cabinet.

■ Earthing terminals—Two protective earthing terminals, PEM nuts at the rear of

the chassis ensure safe dissipation of static electricity in all situations.

Chapter 2: J-series Services Router Hardware Features

■ ESD point—One electrostatic discharge (ESD) point, a banana plug receptacle at

the front of the chassis, minimizes the risk of electrical discharge in potentially hazardous environments.

The router must be connected to earth ground during normal operation. The protective earthing terminals on the rear of the chassis are provided to connect the router to ground (see Figure 14 on page 22). Additional grounding is provided to an AC-powered router when you plug its power supply into a grounded AC power receptacle.

For additional safety information, see “Safety and Regulatory Compliance Information” on page 197.

PIM Overview

J-series Services Routers accept Physical Interface Modules (PIMs) in the slots on the front of the chassis.

CAUTION: PIMs are not hot-swappable. You must power off the Services Router before removing or inserting a PIM module. Ensure that the PIMs are installed in the router chassis before booting up the system.

A Physical Interface Module (PIM) is a network interface card that is installed on a J-series Services Router to provide physical connections to a LAN or a WAN. The PIM receives incoming packets from the network and transmits outgoing packets to the network. Each PIM is equipped with a dedicated network processor that forwards incoming data packets to the Routing Engine and receives outgoing data packets from the Routing Engine. During this process, the PIM performs framing and line-speed signaling for its medium type.

For a complete list of supported PIMs, see “Field-Replaceable PIMs” on page 38.

PIM Terms

A single WXC Integrated Services Module (also called an ISM 200) can be installed like a PIM in J2350, J4350, and J6350 routers to provide WAN acceleration. For more information, see the WXC Integrated Services Module Installation and Configuration Guide.

ITU-T Standard G.992.1 that defines how ADSL works over plain old telephone service (POTS) lines.

ITU-T Standard G.992.1 that defines how ADSL works over Integrated Services Digital Network (ISDN) lines.

ISDN cost-control feature defining the bandwidth threshold that must be reached on all links before a Services Router initiates additional ISDN data connections to provide more bandwidth.

ISDN interface intended for home and small enterprise applications. BRI consists of two 64-Kbps B-channels and one 16-Kbps D-channel.

Alternative feature to dial-in that enables a J-series Services Router to call back the caller from the remote end of a backup ISDN connection. Instead of accepting a call from the remote end of the connection, the router rejects the call, waits a configured period of time, and calls a number configured on the router's dialer interface. See also dial-in.

Telephone number of the caller on the remote end of a backup ISDN connection, used to dial in and also to identify the caller. Multiple caller IDs can be configured on an ISDN dialer interface. During dial-in, the router matches the incoming call's caller ID against the caller IDs configured on its dialer interfaces. Each dialer interface accepts calls from only callers whose caller IDs are configured on it.

dial-in

Interface that a Services Router (the DTE) uses to exchange information with a serial device such as a modem (the DCE).

A DTE cable uses a male 9-pin or 25-pin connector, and a DCE cable uses a female 9-pin or 25-pin connector.

Interface configured for dial-on-demand routing backup. In OSPF, the demand circuit reduces the amount of OSPF traffic by removing all OSPF protocols when the routing domain is in a steady state.

Feature that reestablishes network connectivity through one or more backup ISDN dialer interfaces after a primary interface fails. When the primary interface is reestablished, the ISDN interface is disconnected.

Feature that enables J-series Services Routers to receive calls from the remote end of a backup ISDN connection. The remote end of the ISDN call might be a service provider, a corporate central location, or a customer premises equipment (CPE) branch office. All incoming calls can be verified against caller IDs configured on the router's dialer interface. See also callback.

dial-on-demand-routing (DDR) backup

dialer watch

“dying gasp” notification

ePIM

Stateless firewall filter that enables dial-on-demand routing backup when applied to a physical ISDN interface and its dialer interface configured as a passive static route. The passive static route has a lower priority than dynamic routes. If all dynamic routes to an address are lost from the routing table and the router receives a packet for that address, the dialer interface initiates an ISDN backup connection and sends the packet over it. See also dial-on-demand routing backup; floating static route.

Feature that provides a J-series Services Router with full-time connectivity across an ISDN line. When routes on a primary serial T1, E1, T3, E3, Fast Ethernet, or PPPoE interface are lost, an ISDN dialer interface establishes a backup connection. To save connection time costs, the Services Router drops the ISDN connection after a configured period of inactivity. Services Router with ISDN interfaces support two types of dial-on-demand routing backup: on-demand routing with a dialer filter and dialer watch. See also dialer filter; dialer watch.

Dial-on-demand routing (DDR) backup feature that provides reliable connectivity without relying on a dialer filter to activate the ISDN interface. The ISDN dialer interface monitors the existence of each route on a watch list. If all routes on the watch list are lost from the routing table, dialer watch initiates the ISDN interface for failover connectivity. See also dial-on-demand routing backup.

Ability of a Services Router with a digital subscriber line (DSL) connection that has lost power to send a message informing the attached DSL access multiplexer (DSLAM) that it is about to go offline.

Enhanced PIM. A particular type of high-speed PIM, such as the Gigabit Ethernet ePIM or 4-port Fast Ethernet ePIM, which can be inserted only in high-speed slots (slots 3 and 6 on a J4350 Services Router, or slots 2, 3, 5, and 6 on a J6350 Services Router).

Route with an administrative distance greater than the administrative distance of the dynamically learned versions of the same route. The static route is used only when the dynamic routes are no longer available. When a floating static route is configured on an interface with a dialer filter, the interface can be used for backup.

Interface between an ISDN network and a network termination device consisting of two twisted pairs, one each for transmitting and receiving. The S/T interface usually resides in the customer premises and operates at 192 Kbps, of which ISDN traffic accounts for 144 Kbps.

Single twisted–pair interface line connecting the customer premises unit in an ISDN network to the central office. A U interface runs at 144 Kbps (128 Kbps for two B channels and 16 Kbps for the D channel).

Standard telephone service that allows limited speed and bandwidth of 52 Kbps, which is also know as public switched telephone network (PSTN).

ISDN service intended for higher-bandwidth applications than ISDN BRI. ISDN PRI consists of a single D-channel for control and signaling, plus a number of 64-Kbps B-channels—either 23 B-channels on a T1 line or 30 B-channels on an E1 line—to carry network traffic.

Universal switching PIM. A particular type of PIM, such as the Gigabit Ethernet uPIM, which can be universally inserted in any slot on a J2320, J2350, J4350, or J6350 Services Router.

Field-Replaceable PIMs

PIMs are removable and insertable only when the Services Router is powered off. You install PIMs into slots in the router chassis. If a slot is not occupied by a PIM, a PIM blank panel must be installed to shield the empty slot and to allow cooling air to circulate properly through the router.

42 ■ Field-Replaceable PIMs

Chapter 3: PIM Overview

Features. Gigabit Ethernet uPIMs provide the following key features:

■ The multiport uPIMs can be used as switches in the access layer (for connections

to workstations and desktops). For more information, see the JUNOS Software Interfaces and Routing Configuration Guide.

■ Link speed for 8-port and 16-port Gigabit Ethernet uPIMs is configurable to 10,

100, or 1000 Mbps, and transmission mode is configurable to half or full duplex. The 1-port and 6-port SFP Gigabit Ethernet uPIMs cannot be manually configured—they are set at 1000 Mbps and full duplex.

■ Autonegotiation.

■ 1-port and 6-port Gigabit Ethernet uPIMs use SFP transceivers to allow different

connectors to be used on uPIM ports. These SFP Gigabit Ethernet uPIMs support 1000Base-SX, 1000Base-LX, and 1000Base-T SFPs. They do not support 1000Base-LH SFPs.

1000Base-SX and 1000Base-LX SFP transceivers have the following characteristics:

■ Duplex LC/PC connector (Rx and Tx).

■ Optical interface support—See the JUNOS Software Administration Guide.

■ 8-port and 16-port Gigabit Ethernet uPIMs—and SFPs on the 1-port and 6-port

uPIMs—support 1000Base-T RJ-45 connectors.

For pinouts of cable connectors for Gigabit Ethernet uPIMs, see “Gigabit Ethernet uPIM RJ-45 Connector Pinout” on page 189.

Limitations. Gigabit Ethernet uPIMs have the following limitations:

■ Gigabit Ethernet uPIMs do not support SNMP.

■ Gigabit Ethernet uPIM interfaces can be configured up to a maximum MTU size

of 9014 bytes.

Installation. Gigabit Ethernet uPIMs can be inserted in any slot on J2320, J2350, J4350, or J6350 Services Routers.

Throughput for a uPIM is higher when it is inserted in a high-speed slot. High-speed slots are slots 3 and 6 on the J4350 router, and slots 2, 3, 5, and 6 on the J6350 router.

16-port Gigabit Ethernet uPIMs are two slots high. Because the connector on the PIM is on the lower half, the PIM occupies the slot that it is plugged into and the slot above it. Thus you cannot install a 16-port uPIM in the top slots of a router. For example, on a J4350 router you cannot install a 16-port uPIM in slots 1 and 4. If you install the PIM in slot 2, it occupies both slots 2 and 1.

To install or remove a PIM, see “Replacing a PIM” on page 120.

Interface LEDs. For 8-port and 16-port Gigabit Ethernet uPIMs, the activity LED is located on the left side of each port, and the link LED is located on the right side of each port. For the 6-port Gigabit Ethernet uPIM, the LEDs are located to the right of each port, with the link LED above the activity LED. LEDs on the 1-port uPIM are clearly labeled.Table 21 on page 44 describes the meaning of the LEDs.

Chapter 4

Preparing for Router Installation

Before installing a J-series Services Router, make sure that your site has the proper operating environment and equipment. Use the checklist at the end of the chapter to help you prepare your site.

This chapter discusses the following topics:

■ General Site Guidelines on page 63

■ Rack Requirements on page 64

■ Router Environmental Tolerances on page 66

■ Fire Safety Requirements on page 66

■ Power Guidelines, Requirements, and Specifications on page 67

■ Network Cable Specifications on page 74

■ ISDN Provisioning on page 74

■ Site Preparation Checklist on page 75

General Site Guidelines

The following precautions help you plan an acceptable operating environment for your Services Router and avoid environmentally caused equipment failures:

■ For the cooling system to function properly, the airflow around the chassis must

be unrestricted. Ensure that there is adequate circulation in the installation location. In J2320 and J2350 routers, allow at least 6 in. (15.2 cm) of clearance between the left and right sides of the chassis and adjacent equipment. In J4350 and J6350 routers, allow at least 6 in. (15.2 cm) of clearance between the front and back of the chassis and adjacent equipment.

■ Follow ESD procedures described in “Preventing Electrostatic Discharge

Damage” on page 201, to avoid damaging equipment. Static discharge can cause components to fail completely or intermittently over time.

■ Install blank PIM panels in empty slots, to prevent any interruption or reduction

in the flow of air across internal components.

General Site Guidelines ■ 63

JUNOS Software with Enhanced Services Hardware Guide

Rack Requirements

J-series Services Routers must be installed in a rack. Many types of racks are acceptable, including front-mount racks, four-post (telco) racks, and center-mount racks.

The following sections describe rack requirements:

■ Rack Size and Strength for J2320 and J2350 Routers on page 64

■ Rack Size and Strength for J4350 and J6350 Routers on page 65

■ Connection to Building Structure on page 65

Rack Size and Strength for J2320 and J2350 Routers

The J2320 and J2350 Services Routers are designed for installation in a rack that complies with either of the following standards:

■ A 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment

(document number EIA-310-D) published by the Electronics Industry Association (http://www.eia.org)

■ A 600-mm rack as defined in the four-part Equipment Engineering (EE); European

telecommunications standard for equipment practice (document numbers ETS 300

119-1 through 119-4) published by the European Telecommunications Standards Institute (http://www.etsi.org)

The horizontal spacing between the rails in a rack that complies with this standard is usually wider than the router's mounting ears, which measure 19 in. (48.2 cm) from outer edge to outer edge. Use approved wing devices to narrow the opening between the rails as required.

The rack rails must be spaced widely enough to accommodate the router chassis's external dimensions:

■ J2320 chassis—1.75 in. (4.45 cm) high, 17.51 in. (44.48 cm) wide, and 15.1 in.

(38.35 cm) deep.

■ J2350 chassis—2.61 in. (6.63 cm) high, 17.51 in. (44.48 cm) wide, and 15.1 in.

(38.35 cm) deep.

The outer edges of the mounting ears extend the width of either chassis to 19 in. (48.2 cm), and the front of the chassis extends approximately 0.78 in. (1.98 cm) beyond the mounting ears. The spacing of rails and adjacent racks must also allow for the clearances around the router and rack. (See “General Site Guidelines” on page 63.)

64 ■ Rack Requirements

CAUTION: If you are mounting the router in a cabinet, be sure that ventilation is

sufficient to prevent overheating.

If a front-mount rack is used, we recommend supporting the back of the router with a shelf or other structure.

The J2320 chassis height of 1.75 in. (4.45 cm) equals 1 U. The J2350 chassis height of 2.61 in. (6.63 cm) equals 1.5 U. Each U is a standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association.

119-1 through 119-4) published by the European Telecommunications Standards Institute (http://www.etsi.org)

Chapter 4: Preparing for Router Installation

The rack rails must be spaced widely enough to accommodate the router chassis's external dimensions: 3.44 in. (8.74 cm) high, 17.44 in. (44.3 cm) wide, and 21.13 in. (53.67 cm) deep.

The outer edges of the mounting ears extend the width of either chassis to 19.44 in. (48.38 cm), and the front of the chassis extends approximately 0.5 in. (1.27 cm) beyond the mounting ears. The spacing of rails and adjacent racks must also allow for the clearances around the router and rack. (See “General Site Guidelines” on page 63.)

CAUTION: If you are mounting the router in a cabinet, be sure that ventilation is sufficient to prevent overheating.

If a front-mount rack is used, we recommend supporting the back of the router with a shelf or other structure.

The J4350 and J6350 chassis height of 3.44 in. (8.74 cm) equals 2 U. Each U is a standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association.

Connection to Building Structure

Always secure the rack to the structure of the building. If your geographical area is subject to earthquakes, bolt the rack to the floor. For maximum stability, also secure the rack to ceiling brackets. For more information, see “Rack-Mounting Requirements and Warnings” on page 217.

Fire Safety Requirements

In the event of a fire emergency involving Services Routers and other network equipment, the safety of people is the primary concern. Establish procedures for protecting people in the event of a fire emergency, provide safety training, and properly provision fire-control equipment and fire extinguishers.

In addition, establish procedures to protect your equipment in the event of a fire emergency. Juniper Networks products must be installed in an environment suitable for electronic equipment. We recommend that fire suppression equipment be available in the event of a fire in the vicinity of the equipment, and that all local fire, safety, and electrical codes and ordinances be observed when you are installing and operating your equipment.

Fire Suppression

In the event of an electrical hazard or an electrical fire, first unplug the power cord. (For shutdown instructions, see “Powering a Services Router On and Off” on page 89.)

66 ■ Router Environmental Tolerances

Then, use a Type C fire extinguisher, which uses noncorrosive fire retardants, to extinguish the fire. For more information about fire extinguishers, see “Fire Suppression Equipment” on page 67.

Fire Suppression Equipment

Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide (CO2) and Halotron, are most effective for suppressing electrical fires. Type C fire extinguishers displace the oxygen from the point of combustion to eliminate the fire. For extinguishing fire on or around equipment that draws air from the environment for cooling, use this type of inert oxygen displacement extinguisher instead of an extinguisher that leave residues on equipment.

Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire extinguishers) near Juniper Networks equipment. The primary ingredient in these fire extinguishers is monoammonium phosphate, which is very sticky and difficult to clean. In addition, in minute amounts of moisture, monoammonium phosphate can become highly corrosive and corrodes most metals.

Chapter 4: Preparing for Router Installation

NOTE: To keep warranties effective, do not use a dry chemical fire extinguisher to control a fire at or near a Juniper Networks router. If a dry chemical fire extinguisher is used, the unit is no longer eligible for coverage under a service agreement.

Any equipment in a room in which a chemical fire extinguisher has been discharged is subject to premature failure and unreliable operation. The equipment is considered to be irreparably damaged.

We recommend that you dispose of any irreparably damaged equipment in an environmentally responsible manner.

Power Guidelines, Requirements, and Specifications

All Services Routers are available with AC power. J2350, J4350, and J6350 routers are also available with DC power. For information about each router's power system, see “J4350 Power System” on page 30 and “J6350 Power System” on page 31.

JUNOS Software with Enhanced Services Hardware Guide

Site Electrical Wiring Guidelines

WARNING: Certain ports on the router are designed for use as intrabuilding (within-the-building) interfaces only (Type 2 or Type 4 ports as described in

GR-1089-CORE, Issue 4) and require isolation from the exposed outside plant (OSP)

cabling. To comply with NEBS requirements and protect against lightening surges and commercial power disturbances, the intrabuilding ports must not be metallically connected to interfaces that connect to the OSP or its wiring. The intrabuilding ports on the router are suitable for connection to intrabuilding or unexposed wiring or cabling only. The addition of primary protectors is not sufficient protection for connecting these interfaces metallically to OSP wiring.

WARNING: DC-powered J2350, J4350 and J6350 Services Routers are intended for installation only in a restricted access location.

When planning the electrical wiring at your site, consider the factors discussed in the following sections.

Signaling Limitations

Improperly installed wires can emit radio interference. In addition, the potential for damage from lightning strikes increases if wires exceed recommended distances, or if wires pass between buildings. The electromagnetic pulse (EMP) caused by lightning can damage unshielded conductors and destroy electronic devices. If your site has previously experienced such problems, you might want to consult experts in electrical surge suppression and shielding.

Radio Frequency Interference

You can reduce or eliminate the emission of radio frequency interference (RFI) from your site wiring by using twisted-pair cable with a good distribution of grounding conductors. If you must exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.

Electromagnetic Compatibility

If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, you might want to seek expert advice. Strong sources of electromagnetic interference (EMI) can destroy the signal drivers and receivers in the router and conduct power surges over the lines into the equipment, resulting in an electrical hazard. It is particularly important to provide a properly grounded and shielded environment and to use electrical surge-suppression devices.

68 ■ Power Guidelines, Requirements, and Specifications

Chapter 4: Preparing for Router Installation

CAUTION: To comply with intrabuilding lightning/surge requirements, intrabuilding wiring must be shielded, and the shield for the wiring must be grounded at both ends.

NOTE: The AC power cord for the Services Router is intended for use with the router only and not for any other use.

Power Guidelines, Requirements, and Specifications ■ 69

JUNOS Software with Enhanced Services Hardware Guide

Detachable AC power cords, each 2.5 m (approximately 8 ft) long, are supplied with the Services Router. The appliance coupler at the female end of the cord inserts into the appliance inlet on the faceplate of the AC power supply. The coupler is type C19 as described by International Electrotechnical Commission (IEC) standard 60320. The plug at the male end of the power cord fits into the power source receptacle that is standard for your geographical location.

NOTE: In North America, AC power cords must not exceed 4.5 m (approximately

14.75 ft) in. length, to comply with National Electrical Code (NEC) Sections 400-8 (NFPA 75, 5-2.2) and 210-52, and Canadian Electrical Code (CEC) Section 4-010(3). The cords supplied with the router are in compliance.

For information about the AC power supply, see “J2320 Power System” on page 18, “J2350 Power System” on page 18, “J4350 Power System” on page 30 or “J6350

Power System” on page 31.

To connect the power cord during initial installation, see “Connecting Power” on page 84.

To replace the AC power cord, see “Replacing AC Power Supply Cords” on page 139.

DC Power, Connection, and Power Cable Specifications

Each DC power supply has a single DC input (–48 VDC and return) that requires a dedicated circuit breaker:

■ J2350 routers—minimum 15 A (–48 VDC)

■ J4350 and J6350 routers—minimum 25 A (–48 VDC)

If the J6350 router contains redundant DC power supplies, one power supply must be powered by a dedicated power feed derived from feed A, and the other power supply must be powered by a dedicated power feed derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.

Chapter 4: Preparing for Router Installation

Most sites distribute DC power through a main conduit that leads to frame-mounted DC power distribution panels, one of which might be located at the top of the rack that houses the router. A pair of cables (one input and one return) connects each set of terminal studs to the power distribution panel.

CAUTION: You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each power supply.

WARNING: Power plant ground and chassis ground must be connected to the same building ground.

CAUTION: Before router installation begins, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the router.

Each DC power cable (–48 VDC and return) must be 14 AWG single-strand wire cable, or as permitted by the local code. Each lug attached to the power cables must be a ring-type, vinyl-insulated TV14-6R lug, or equivalent.

To replace a DC power cable, see “Replacing DC Power Supply Cables” on page 142.

Planning for Power Management

Before you install a chassis or add a new PIM to an existing chassis, verify that the combination of PIMs and modules (PIMs or PIMs plus a WXC Integrated Services Module) to be installed does not exceed the power and heat capacities for that model. Add the low-power tokens, high-power tokens, and heat tokens required by each PIM, and compare them to the capacity of the chassis.

NOTE: The low power and high power correspond to a specific voltage for that PIM.

CAUTION: Do not install a combination of modules in a single chassis that exceeds

the maximum power and heat capacity of the chassis. If J-series power management is enabled, PIMs and modules (PIMs or PIMs plus a WXC Integrated Services Module) that exceed the maximum power and heat capacity remain offline when the chassis is powered on.

To verify that the combination of PIMs to be installed in a chassis does not exceed the power and heat capacities for that model:

1. Check Table 38 on page 73 to determine the token values for low-power,

high-power, and heat for each PIM that you plan to install in the chassis.

2. For all PIMs to be installed in the chassis:

a. Add the low-power tokens for all PIMs to be installed in the chassis.

b. Add the high-power tokens for all PIMs to be installed in the chassis.

c. Add the heat dissipation tokens for all PIMs to be installed in the chassis.

3. Verify that the total number of low-power tokens, total number of high-power

tokens, and the total number of heat dissipation tokens do not exceed the maximums permitted for your J-series chassis as specified in Table 39 on page 74.

Table 38 on page 73 shows the low-power consumption, high-power consumption, and heat dissipation, represented in non-dimensional tokens, assigned to each J-series PIM.
