Industry Canada Notice CS-03

The Industry Canada label identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective, operation and safety requirements as prescribed in the appropriate Terminal Equipment Technical Requirements document(s). The Department does not guarantee the equipment will operate to the user's satisfaction. Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using and acceptable method of connection. The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.

Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.

Notice: The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the maximum number of terminals allowed to be connected to a telephone interface. The termination on an interface may consist of any combination of devices subject only to the requirement that the sum of the Ringer Equivalence Numbers of all the devices does not exceed 5.

Avis CS-03 d’Industrie Canada

L’étiquette du ministère des Communications du Canada indique que l’appareillage est certifié, c’est-à-dire qu’il respecte certaines exigences de sécurité et de fonctionnement visant les réseaux de télécommunications. Le ministère ne garantit pas que l’appareillage fonctionnera à la satisfaction de l’utilisateur. Avant d’installer l’appareillage, s’assurer qu’il peut être branché aux installations du service de télécommunications local. L’appareillage doit aussi être raccordé selon des méthodes acceptées. Le client doit toutefois prendre note qu’une telle installation n’assure pas un service parfait en tout temps.

Les réparations de l’appareillage certifié devraient être confiées à un service d’entretien canadien désigné par lefournisseur. En cas de réparation ou de modification effectuées par l’utilisateur ou de mauvais fonctionnement del’appareillage, le service de télécommunications peut demander le débranchment de l’appareillage.

Pour leur propre sécurité, les utilisateurs devraient s’assurer que les mises à la terre des lignes de distribution d’électricité, des lignes téléphoniques et de la tuyauterie métallique interne sont raccordées ensemble. Cette mesure de sécurité est particulièrement importante en milieu rural.

Attention: Les utilisateurs ne doivent pas procéder à ces raccordements eux-mêmes mais doivent plutôt faire appel aux pouvoirs de réglementation en cause ou à un électricien, selon le cas.

Avis: Veuillez prendre note que pour tout appareillage supportant des lignes de type “loopstart,” l'indice d'équivalence de la sonnerie (IES) assigné à chaque dispositif terminal indique le nombre maximal de terminaux qui peuvent être raccordés à une interface. La terminaison d'une interface téléphonique peut consister en une combinaison de quelques dispositifs, à la seule condition que la somme d'indices d'équivalence de la sonnerie de tous les dispositifs n'excède pas 5. Le REN figure sur l’étiquette “FCC Rules Part 68” située sur le support du module ou à l’arrière de l’unité.

D.O.C. Explanatory Notes: Equipment Attachment Limitations

The Canadian Department of Communications label identifies certified equipment. This certification meets certain telecommunication network protective, operational and safety requirements. The department does not guarantee the equipment will operate to the users satisfaction.

Before installing the equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the company’s inside wiring associated with a single line individual service may be extended by means of a certified connector assembly (telephone extension cord). The customer should be aware that compliance with the above condition may not prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electrical inspection authority, or electrician, as appropriate.

Notes explicatives du ministère des Communications: limites visant les accessoires

Avant d’installer l’appareillage, s’assurer qu’il peut être branché aux installations du service de télécommunications local. L’appareillage doit aussi être raccordé selon des méthodes acceptées. Dans certains cas, le câblage interne du service de télécommunications utilisé pour une ligne individuelle peut être allongé au moyen d’un connecteur certifié (prolongateur téléphonique). Le client doit toutefois prendre note qu’une telle installation n’assure pas un service parfait en tout temps.

Les réparations de l’appareillage certifié devraient être confiées à un service d’entretien canadien désigné par le fournisseur. En cas de réparation ou de modification effectuées par l’utilisateur ou de mauvais fonctionnement de l’appareillage, le service de télécommunications peut demander le débranchment de l’appareillage.

Attention: Les utilisateurs ne doivent pas procéder à ces raccordements eux-mêmes mais doivent plutôt faire appel aux pouvoirs de réglementation en cause ou à un électricien, selon le cas.

The systems offer high port density, low power consumption, and fully redundant Internet access routing and edge aggregation. The ERX edge routers offer the complete edge solution for IP-optimized carriers.

Four models of the ERX edge router are available:

• ERX-1440 system

• ERX-1410 system

• ERX-705 system

• ERX-700 system

CHAPTER 1

1-2

ERX System Overview

ERX-1400 Series

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

• The combination of line modules supported

• The conditions for line rate performance of line modules

In the ERX documentation, the term ERX-1400 series refers to both the ERX-1440 system and the ERX-1410 system. The terms ERX-1440 system and ERX-1410 system refer to the specific models.

The ERX-1440 system manages an extremely high volume of network traffic and uses a 40-Gbps switch route processor (SRP) module, either the SRP-40G or SRP-40G+ module. (The SRP-40G+ module obsoletes the SRP-40G module; however, the software continues to support both modules.) In this model, all line modules operate at full wire speed simultaneously.

The ERX-1410 system manages high levels of network traffic, and uses the 10-Gbps SRP module (SRP-10G). You can configure the ERX-1410 system to enable the line modules either to operate at full line rate performance or to allow line modules to operate at a rate dependent on the resources available. The former option restricts the allowed combinations of line modules. For information on configuring performance of line modules, see ERX System Basics Configuration

Guide, Chapter 5, Managing Line Modules and SRP Modules.

Externally, the ERX-1440 chassis is the same as the ERX-1410 chassis (see Figure 1-1 and Figure 1-2). Both systems contain fourteen vertical slots to accommodate modules and have the same power requirements. Installation procedures and operating procedures are identical for both systems. All ERX systems use the same SRP I/O modules.

Note: The system may look different from the systems shown in the figures in this chapter, depending on the line modules in the slots.

Internally, the ERX-1440 chassis differs from the ERX-1410 chassis, and includes a special midplane for the 40-Gbps SRP module.

In the ERX documentation, the term ERX-700 series refers to both the ERX-705 system and the ERX-700 system. The terms ERX-705 system and ERX-700 system refer to the specific models.

The ERX-705 system is a compact, high-performance model that manages low traffic density and uses a 5-Gbps SRP module, the SRP-5G+ module. The ERX-700 system is a robust, high-density system with less capacity than the ERX-1400 series. The ERX-700 system uses either the SRP-10G module or a 5-Gbps SRP module, the SRP-5G module. (Although the SRP-5G+ module obsoletes the SRP-5G module; the software continues to support both modules.)

You can configure the ERX-700 series to enable the line modules either to operate at full line rate performance or to operate at a rate dependent on the resources available. For information about configuring performance of line modules, see ERX System Basics Configuration

Guide, Chapter 5, Managing Line Modules and SRP Modules.

ERX System Modules

The 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 Internet.

Each module connects to a corresponding I/O module via a passive midplane. See Figure 1-7.

The front panel of each system module contains a collection of status LEDs (light-emitting diodes). See Figure 1-8. For information about how to interpret the LEDs, see Chapter 8, Troubleshooting.

CHAPTER 1

1-8

ERX System Overview

SRP Module

The SRP module (see Figure 1-8) is a two-board assembly; both boards connect to the system’s midplane and to each other:

• The fabric board is a switch fabric server that queues packets for the

line modules. The fabric server houses a flexible hardware queuing resource that empowers IP QoS for each physical and logical interface, providing weighted scheduling for preferential packet delivery.

• The system processor board is the dedicated processor that boots the

system, manages diagnostics, and supports routing protocol processing.

An SRP module must be present for the system to boot. For details about installing SRP modules, see Chapter 3, Installing ERX Modules. For specifications of SRP modules, see Appendix B, Module Specifications.

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

You can install two SRP modules of the same type in the system. If you do, the first SRP module serves as the primary; the second as a redundant module, which enhances the system’s reliability. See

Redundancy Features, later in this chapter.

Nonvolatile Storage

The PCMCIA slot on the front of the SRP module holds a Type II PCMCIA nonvolatile storage (NVS) card. This card retains the system’s configuration and software. See Figure 1-8. The PCMCIA card is factory installed.

SRP I/O Module

Figure 1-8 SRP module

A single corresponding input/output module called the SRP I/O module interfaces with one or two SRP modules through the system’s midplane. The same SRP I/O works with all models of the SRP module. This I/O module is two slots wide. See Figure 1-2 and Figure 1-4.

The SRP module provides standard craft management interfaces, including:

• 10/100Base-T – a port for Ethernet management

• RS-232 – a port for VT100 management access

• External timing inputs – ports for external timing sources

For details about installing the SRP I/O module, see Chapter 3, Installing

ERX Modules.

CHAPTER 1

ERX System Overview

Line Modules

Line modules process data from different types of network connections. For information about the available line modules and which SRP modules support specific line modules, see Appendix B, Module

Specifications.

Figure 1-9 shows a representative line module. For details about installing

line modules, see Chapter 3, Installing ERX Modules.

Packet Classification

Each line module supports packet classification on ingress. A classification engine on the line module matches specific fields (such as source and destination IP address, source and destination port, and protocol), the ingress IP interface, layer 2 fields, or some combination of these against user-configured filters at wire speed.

I/O Modules

Most line modules have a corresponding input/output (I/O) module that provides the physical interconnection to the network. Insert each I/O module in the back of the system, directly behind its corresponding line module. For information about which line modules pair with which I/O modules, see Appendix B, Module Specifications. For details about installing I/O modules, see Chapter 3, Installing ERX Modules.

Network Management Tools

You can use different management tools to configure the system to meet the specific networking requirements.

CLI Management

The CLI provides fully developed and automated configuration and status functionality through a local RS-232 port, an Ethernet connection, or Telnet through any reachable network. For a full discussion of the CLI, see ERX System Basics Configuration Guide, Chapter 2, Command

Line Interface.

SNMP MIB Management

The system offers a complete SNMP interface for configuration, status, and alarm reporting. The system supports both Standard and Enterprise MIBs (Management Information Bases). The ERX Enterprise MIB is ASN.1 notated for easy importing into third-party SNMP management applications. For more information, see ERX System Basics

Configuration Guide, Chapter 3, Configuring SNMP.

NMC-RX Device Management System

The NMX-RX application provides a global method of managing all edge routers, line modules, and ports.

Redundancy Features

The system has the following redundancy features:

SRP Modules

The SRP module uses a 1:1 redundancy scheme. When two SRP modules of the same type are installed in the system chassis, one acts as a primary and the second as a standby. Both SRP modules share a single

CHAPTER 1

1-12

ERX System Overview

SRP I/O module located in the rear of the chassis. If the primary SRP fails, the redundant SRP module assumes control without rebooting or initializing itself. (As a consequence, if you upgrade software, you must copy the software to the redundant SRP and reboot it.) For information about configuring and managing SRP module redundancy, see ERX

System Basics Configuration Guide, Chapter 5, Managing Line Modules and SRP Modules.

After you install two SRP modules, the modules negotiate for the primary role. A number of factors determine which module becomes the primary; however, preference is given to the module in the lower-numbered slot. The SRP modules record their latest roles and retain them the next time you switch on the system. For information about installing SRP modules, see Chapter 3, Installing ERX Modules.

NVS Cards

If you have two SRP modules installed in a system, you can use NVS cards of different capacities on the SRP modules. The effective capacity of the higher-capacity NVS card will equal that of the lower-capacity NVS card. For information about installing NVS cards, see Chapter 3,

Installing ERX Modules.

When you install new NVS cards or SRP modules, you must issue the synchronize command to match the file system of the NVS card on the redundant SRP module with the file system of the NVS card on the primary SRP module. (The NVS card on the redundant SRP module will hereafter be referred to as the redundant NVS card; the NVS card on the primary SRP module will hereafter be referred to as the primary NVS card.)

If the capacity of the primary NVS card is equal to or smaller than that of the redundant NVS card, the system copies all the files from the primary NVS card to the redundant NVS card. However, if the capacity of the primary NVS card exceeds that of the redundant NVS card, the system creates an invisible synchronization reserve file on the primary NVS card, provided that there is enough space for the f ile.

The purpose of the synchronization file is to prevent the creation of data that will not fit on the redundant NVS card. The file contains no useful data, and is not visible when you view the files in NVS. The size of the file is equal to the difference in capacities of the two NVS cards. For example, if the primary NVS card has a capacity of 224 MB, and the redundant NVS card has a capacity of 220 MB, the size of the synchronization file is 4 MB, and only 220 MB of space is available on the primary NVS card.

Line Modules

Redundancy Features

ERX Edge Routers

If there is not enough space on the primary NVS card to create the synchronization reserve file, the synchronize command fails, and you see a warning message on the console. To resolve this issue, either delete unwanted files from the primary NVS card or replace the redundant NVS card with a higher-capacity NVS card.

The ERX system supports line module redundancy for several line modules. For details about which line modules support redundancy, see

Appendix B, Module Specifications. In this scheme, an extra line access

module in a group of identical line modules provides redundancy in case of line module failure. To use this feature, you need a:

• Spare line module

• Redundancy midplane

• Redundancy I/O module

A redundancy midplane may cover 2–6 slots. It provides additional connectivity that enables the spare line module to assume control of the I/O module associated with any failed line module in the redundancy group. The spare I/O module provides connectivity from the spare line module to the redundancy midplane.

1-13

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 1-10 shows the data flow when a spare line module becomes

active.

CHAPTER 1

1-14

ERX System Overview

A packet arrives at the primary I/O module.

The packet passes along the redundancy midplane from the primary I/O module to the redundancy I/O module.

The packet passes from the redundancy I/O module to the spare line module.

The spare line module processes the packet.

and managing SRP module redundancy, see ERX System Basics

Configuration Guide, Chapter 5, Managing Line Modules and SRP Modules, for more information.

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

Fans

The Next Step

ERX Edge Routers

Forced air-cooling keeps the temperature of the ERX modules and components within normal operating limits. In the ERX-1400 series, six cooling fans are located in a tray at the top of the system (see Figure 7-5). In the ERX-700 series, four cooling fans are located in a tray on one side of the system (see Figure 7-7).

The system monitors the temperature of each module. If the temperature of a module exceeds the maximum limit, the system immediately goes into thermal protection mode. In this mode, the modules consume extremely low levels of power. For information about troubleshooting high operating temperatures, see Chapter 8, Troubleshooting.

The fan tray has two redundant converters that power the fans (for the ERX-1400 series, a –24 V, 50 W converter; for the ERX-700 series, a –12 V, 15 W converter). If one converter fails, the other takes over. In addition, the system software reports an alarm if any of the fans overrotate or underrotate or if one of the converters fails.

Rack-Mounted Installation

We recommend that you use a standard EIA distribution rack. Refer to

Rack Requirements in Appendix D, Preparing Your Site, for detailed

rack information. Before installing the systems in the rack, consider the following guidelines:

• You can install up to three ERX-1400 series systems in a single 84-inch

rack.

Installing multiple systems in a single rack allows you to maximize your available space. An ERX-1400 series system has a plenum that allows air to circulate between systems.

• You can install an ERX-1400 series system and an ERX-700 series

system together in the same rack.

If you install an ERX-700 series system above an ERX-1400 series system in the same rack, you must install a plenum between the ERX-700 series system and the ERX-1400 series system so that the air can circulate between the systems. See Figure 2-6. This plenum is available from Juniper Networks.

Hot-Swapping Modules

The ERX-700 series and ERX-1400 series support hot-swapping of modules. Hot-swapping allows you to add or remove a module without powering down the system.

Required Tools and Safety Items

You need the following tools to install a line module:

• A Phillips screwdriver

• An ESD (electrostatic discharge) wrist strap

Protecting Modules and Slots

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

Caution: When handling modules, use an antistatic wrist strap connected to the ERX system’s ESD grounding jack. This action helps to protect the module from damage by electrostatic discharge.

Protecting Modules and Slots

ERX Edge Routers

On the ERX-1400 series, the grounding jacks are inside the front bezel in the lower-left area of the front of the chassis (Figure 3-4) and in the upper-right corner on the rear of the chassis. On the ERX-700 series, the grounding jack is in the lower-right corner on the rear of the chassis.

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

Caution: Be sure to cover every empty slot with a blank faceplate to protect the system from dust or other foreign substances and to ensure proper system cooling.

Installing ERX Modules

Safety Guidelines

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

Lightning Activity Warning: Do not work on the system or connect or disconnect cables during lightning activity.

DC Power Disconnection Warning: Before powering on the ERX system, remove power from the DC circuit by deactivating the circuit breaker on the panel board that services the DC circuit.

Jewelry Removal Warning: Remove jewelry (including rings, necklaces, and watches) before working on equipment that is connected to power lines. Metal objects heat up when connected to power and ground and can cause serious burns or become welded to the terminals.

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

Repair Warning: Never attempt to repair parts of modules yourself. Only trained customer service personnel are authorized to service parts. Call Juniper Networks Customer Service to make arrangements to return defective modules for repair. See Appendix F, Customer Service.

Installing SRP I/O and SRP Modules

You should install SRP modules only in chassis slots 6 and 7 of the ERX-1400 series and slots 0 and 1 of the ERX-700 series.

Note: Install the SRP I/O module before you install the SRP module; otherwise, the ERX system diagnostics fail.

Installing an SRP I/O Module

To install an SRP I/O module:

1 Connect the antistatic wrist strap to the ESD grounding jack on your

ERX system.

Caution: When handling modules, use an antistatic wrist strap connected to the ERX system’s ESD grounding jack. This action helps to protect the module from damage by electrostatic discharge.

If you remove an I/O module and not the corresponding line module, the line module reboots, and then its status will be “inactive” when you issue a show version command. If you remove a line module and do not delete the corresponding configuration, the status of the line module will be “not present” when you issue a show version command.

Installing Components for Line Module Redundancy

The ERX system allows a spare line module to provide redundancy for a group of identical line modules. 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 redundancy I/O module

Warning: Do not insert any metal object, such as a screwdriver, or place your hand into an open slot or the backplane when the ERX system is on. Remove jewelry (including rings, necklaces, and watches) before working on equipment that is connected to power lines. These actions prevent electric shock and serious burns.

Caution: When handling modules, use an antistatic wrist strap connected to the ERX system’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 Modules and Their I/O Modules, earlier in this chapter).

Installing the Redundancy Midplane

To install the redundancy midplane in a redundancy group:

Caution: If you do not use the halt command before removing or powering down an SRP, the system’s NVS card may become corrupted.

1 Enter the halt command.

See ERX System Basics Configuration Guide, Chapter 5, Managing

Line Modules and SRP Modules for information about the halt

command.

Warning: Turn off the ERX system before you install the redundancy midplane. Working inside the ERX system when it is on can lead to electric shock and serious burns.

2 Turn off the power switches located on the power input module in

the rear of the system (see Figure 3-11).

3 Remove the I/O modules from the slots that the redundancy

midplane will span.

4 Place the redundancy midplane in the chassis so that it rests against

the guides below the chassis midplane (see Figure 3-11).

5 Align the screw holes in the redundancy midplane with the screw

holes in the guides so that the midplane covers the slots for the redundancy group.

6 Using a Phillips screwdriver and the screws provided, loosely attach,

but do not tighten, the redundancy midplane to the guides.

CHAPTER 3

3-16

Installing ERX Modules

7 Carefully insert an I/O module in one slot to ensure that the

redundancy midplane is aligned correctly; then tighten the screws.

A misaligned redundancy midplane can result in bent pins on the boards and poor contact between the I/O modules and the redundancy midplane.

Chassis midplane

Cabling Redundant Ports

Some modules have redundant ports. See Appendix B, Module

Specifications for specifications. Cabling both ports provides a redundant

path to the ERX module.

Caution: For port redundancy to operate correctly on a GE I/O module that supports SFPs, both the primary and redundant ports on an ERX GE I/O module must use the same type of SFP.

The Next Step

After you have cabled the system, check that all connections go the right places and are secure. Then proceed as follows:

• If you need to set up a console to communicate with the system, go to

Chapter 5, Accessing the ERX System.

• If you have already set up your console, go to Chapter 6, Powering Up

the System.

SNMP 5-6

The Next Step 5-6

Setting Up Management Access

Before you power up the system, you must set up a management console. The console allows you to communicate with the system during the power-up process and to manage the system using the command line interface (CLI).

You can manage and monitor the system by accessing it in the following ways:

• Connect a console (PC, Macintosh, or UNIX workstation) directly to

the system’s RS-232 serial port (DTE).

• Connect the system’s 10/100Base-T port on the SRP I/O module to an

Ethernet network, and run Telnet from a remote console.

CHAPTER 5

5-2

Accessing the ERX System

Console Port Setup

Using HyperTerminal

For initial access to the system, you need to physically connect your console directly to the system’s RS-232 port. This connection allows you to use the CLI to set an IP address on the system. Once you configure the IP address, you can access the system remotely (for example, via Telnet).

You can connect a console (PC, Macintosh, or UNIX workstation) directly to the system via the RS-232 terminal port on the SRP I/O module. When you connect a console directly to the system, you can configure the system without an IP address.

To communicate with the system, you must have a terminal emulation program running on your PC or Macintosh. You can use any terminal emulation program (such as HyperTerminal). A UNIX workstation can use the emulator TIP.

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 screen, in the Connect using field, select

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

6 In the COM1 Properties screen, select the following settings:

• Bits per second: 9600

• Data bits: 8

• Parity: None

• Stop bits: 1

• Flow control: Xon/Xoff

7 Click OK.

Connecting Directly to the ERX System

When you connect a console directly to the system, use a cable appropriate for your terminal connector. The cable must have a female DB-9 connector to attach to the RS-232 port on the system. To connect a console directly to the system:

1 Connect the female DB-9 connector to the RS-232 port on the

system’s SRP I/O module. See Figure 5-1.

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

3 Power up the system.

When you power up the system, the CLI appears on your console’s screen. The system is now in User Exec mode, and you can begin configuration. For more information on using the CLI and configuring the system, see the ERX System Basics Configuration

Guide.

Note: Direct access through the RS-232 serial port allows you to monitor the system as it boots.

Assigning an IP Address

When your console is ready to communicate with the system, power up the system (see Chapter 6, Powering Up the System), and set an IP

CHAPTER 5

5-4

Accessing the ERX System

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

1 Enter the enable command at the User Exec prompt.

host1>enable

host1#

The system is now in Privileged Exec mode.

2 Set an IP address on the Ethernet interface:

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

the slotnumber variable.

• 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.

Telnet Setup

After you have assigned an IP address to the system, you can communicate remotely by running Telnet over an Ethernet network. See the next section, Tel ne t S e tu p .

When you have configured an IP address for the system, you can run Telnet on your console to access the system through its Ethernet port. To connect the console to the system:

1 Connect an Ethernet cable (RJ-45) to the system’s 10/100Base-T

(RJ-45) port on the SRP I/O module.

2 Connect the other end of the cable to the appropriate Ethernet

network for an out-of-band connection.

Before you can access the system with Telnet, you must either configure a password for Telnet access or disable the password requirement from the management console. In the following example, you disable the password.

1 Enter the enable command.

host1>enable

host1#

Telnet Setup

ERX Edge Routers

The system is now in Privileged Exec mode.

2 Enter the configure command.

SNMP

The Next Step

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 the ERX System Basics Configuration

Guide, Chapter 3, Configuring SNMP for information on SNMP. See

the ERX Command Reference Guide for the commands that are available for configuring the system as an SNMP agent.

CHAPTER 7

7-2

Maintaining the ERX System

Storing Modules and Components

Caution: Failure to store electronic modules and components correctly may lead to damage of these items.

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 NVS cards, are shipped in antistatic plastic containers within an antistatic padded box. Follow these guidelines for storing modules and components:

• Store each module in a separate antistatic bag.

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

containers can accommodate several components in separate compartments.

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

container where they can touch other items.

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

protective packaging or padded box that the item was shipped in.

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

Caution: If you do not use the halt command before removing or powering down an SRP, the system’s NVS card may become corrupted.

1 Enter the halt command.

See ERX System Basics Configuration Guide, Chapter 5, Managing

Line Modules and SRP Modules for information about the halt

command.

Upgrading NVS Cards on SRP Modules

Caution: When handling modules, use an antistatic wrist strap connected to the ERX system’s ESD grounding jack. This action helps to protect the module from damage by electrostatic discharge.

2 Connect the antistatic wrist strap to the ESD grounding jack on your

ERX system.

3 Power down the system (see Chapter 6, Powering Up the System).

4 Remove the SRP I/O module.

5 Replace the NVS card on the SRP module (see Replacing an NVS

Card, later in this chapter).

6 Power up the system (see Chapter 6, Powering Up the System).

Upgrading a System That Contains Two SRP Modules

In a system that contains two SRP modules, you can upgrade the NVS cards on the SRP modules without powering down the system.

7-3

ERX Edge Routers

Caution: When handling modules, use an antistatic wrist strap connected to the ERX system’s ESD grounding jack. This action helps to protect the module from damage by electrostatic discharge.

To upgrade the NVS cards on the SRP modules in a system that contains two SRP modules:

1 Connect the antistatic wrist strap to the ESD grounding jack on your

ERX system.

2 Reboot the redundant SRP module.

7 Replace the faceplate on the NVS card slot.

Replacing SFPs on GE I/O Modules

This section describes how to replace small form-factor pluggable transceivers (SFPs) on Gigabit Ethernet (GE) modules that support these devices. A range of SFPs that support different optical modes (multimode and single mode) and cabling distances is available. You can replace the SFPs without disabling the interfaces or removing the module from the system.

Caution: When handling electronic components, use an antistatic wrist strap connected to the system’s ESD grounding jack, and hold components by their edges. Do not touch, pins, leads, or solder connections. Store components in antistatic bags. These actions help to protect modules from damage by electrostatic discharge.
