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.

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 electrical inspection authority, or electrician, as appropriate.

Notes explicatives du ministère des Communications: limites visant
les accessoires

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

users acquire the Software with only the rights set forth in this License Agreement.

10. General: This License shall be governed by and construed in accordance with the laws of the
Commonwealth of Massachusetts, United States of America, as if performed wholly within the state
and without giving effect to the principles of conflict of law. Any dispute arising out of this Agreement
shall be referred to an arbitration proceeding in Boston, Massachusetts, in accordance with the

arbitrator shall not be permitted to award punitive or indirect damages. The arbitrator's decision and
award shall be final and binding and may be entered in any court having jurisdiction. The terms of
this section shall not prevent any party from seeking injunctive relief in any court of competent
jurisdiction in order to protect its proprietary and confidential information. If any term or provision
hereof is found to be void or unenforceable by a court of competent jurisdiction, the remaining
provisions of this License Agreement shall remain in full force and effect. This License Agreement
constitutes the entire agreement between the parties with respect to the use of the Software and
User Documentation and supersedes any and all prior oral or written agreements, discussions,
negotiations, commitments, or understandings. No amendment, modification, or waiver of any
provision of this License Agreement will be valid unless in writing and signed by the authorized
representative of the party against which such amendment, modification, or waiver is sought to be
enforced. The waiver by either party of any default or breach of this License Agreement shall not
constitute a waiver of any other or subsequent default or breach. This License Agreement shall be
binding upon the parties and their respective successors and permitted assigns.

Overview

E-series routers are modular, carrier-class networking devices that deliver
performance, reliability, and service differentiation to both business and
consumer Internet users. The ERX-7xx/14xx models offer high port
density, low power consumption, and fully redundant Internet access
routing and edge aggregation. The ERX-310 router supports the same
services, but with smaller capacity and scaling capabilities. E-series
routers offer the complete edge solution for IP-optimized carriers.

CHAPTER 1

E-Series Overview

Where E-Series Routers Fit In

Communications with the router can take place over a variety of media.

Figure 1-1 and Figure 1-2 illustrate the location of E-series routers as an

edge router in an end-to-end Internet network. In Figure 1-1, the
customers are businesses using T1/T3 communication lines. In

Figure 1-2, the customers are using digital subscriber lines (DSLs) with a

DSL access multiplexer (DSLAM).

CHAPTER 1

1-4

E-Series Overview

ERX-14xx Models

Note: In the E-series documentation, the term ERX-14xx models refers to both the
ERX-1440 router and the ERX-1410 router. The terms ERX-1440 router and
ERX-1410 router refer to the specific models. See Figure 1-4 and Figure 1-5.

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

The ERX-1410 router manages high levels of network traffic, and uses the
10-Gbps SRP module (SRP-10G). You can configure the ERX-1410
router to enable the line modules either to 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 E-Series System Basics Configuration

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

Note: The 10-Gbps SRP module used in the ERX-310 router is different from the
10-Gbps SRP module used in the ERX-1410 router. See section SRP Module,
later in this chapter, for more information.

Externally, the ERX-1440 chassis is the same as the ERX-1410 chassis
(see Figure 1-4 and Figure 1-5). Both routers contain 14 vertical slots to
accommodate modules.

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

Installation procedures and operating procedures are identical for both
systems. All ERX-7xx/14xx models use the same SRP I/O module, but
different power input modules are used.

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

ERX-705 router and the ERX-710 router. The terms ERX-705 router and ERX-710
router refer to the specific models. See Figure 1-6 and Figure 1-7.

The ERX-7xx models are robust, high-density routers with less capacity
than the ERX-14xx models. The ERX-7xx models use either the
SRP-10G module or the SRP-5G module.

You can configure the ERX-7xx models to enable the line modules 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 E-Series System Basics Configuration Guide,

Chapter 5, Managing Line Modules and SRP Modules.

Note: The 10-Gbps SRP module used in the ERX-310 router is different from the
10-Gbps SRP module used in the ERX-710 router. See section SRP Module, later
in this chapter, for more information.

The ERX-705 chassis is the same as the ERX-710 chassis (see Figure 1-6
and Figure 1-7). The chassis contains seven slots to accommodate
modules. Installation procedures and operating procedures are identical
for both systems. All ERX-7xx/14xx models use the same SRP I/O
module, but different power input modules are used.

E-Series Overview

ERX-310 Router

The ERX-310 router is a low-end platform that supports all of the same
services as the ERX-7xx/14xx models, but with smaller capacity and
scaling capabilities. Like the ERX-7xx/14xx models, the ERX-310 router
uses the same software architecture, providing a single IP entry point into
the network with the same IP-based protocols and services that are
available on other E-series routers. The ERX-310 router is designed to be
used as a small distributed POP router as well as a high-end CPE router.

The ERX-310 router is a three-slot chassis with a midplane architecture.
One slot supports one nonredundant 10-Gbps SRP module, while the
other two slots support line modules. The router supports existing E-series
ASIC-based line modules (except the OC48/STM16 line module).

Note: The 10-Gbps SRP module used in the ERX-310 router is different from the
10-Gbps SRP module used in the ERX-7xx/14xx models. See section SRP

Module, later in this chapter, for more information.

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

E-Series Overview

E-Series 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 network.

Each module connects to a corresponding I/O module via a passive
midplane. See Figure 1-11.

The front panel of each module contains a collection of status LEDs
(light-emitting diodes). For information about how to interpret the LEDs,
see Chapter 10, Troubleshooting.

Module Details

ERX-7xx/14xx models use up to two redundant SRP modules operating
in an active/standby conf iguration. ERX-310 routers use only one SRP
module. An SRP module must be present for any system to boot.

SRP modules ranging from 5 Gbps to 40 Gbps can be used in
ERX-7xx/14xx models. Only a 10-Gbps SRP module (SRP-SE10G) can
be used in ERX-310 routers. See Chapter 12, Module Specifications for
complete information.

Note: Because of different physical dimensions and switch fabric capabilities, SRP
modules are not interchangeable between systems. For example, the 10-Gbps
SRP module used in ERX-7xx/14xx models cannot be used in the ERX-310 router,
and vice versa.

E-Series Modules

E-Series Routers

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

For details about installing SRP modules, see Chapter 5, Installing

Modules.

SRP Module Redundancy

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

Redundancy Features, later in this chapter, for more information.

Nonvolatile Storage

The PCMCIA slot on the front of the SRP module holds a Type II
PCMCIA nonvolatile storage (NVS) card (see Figure 1-12 and

Figure 1-13). This card is loaded with the system’s software and

configuration files. The PCMCIA card is factory installed.

The SRP I/O module is a single corresponding input/output module that
interfaces with the SRP module(s) through the system’s midplane. The
same SRP I/O module works with all SRP modules, but is router specific.
The I/O module used in ERX-7xx/14x models cannot be used in the
ERX-310 router, and vice versa. See Figure 1-5, Figure 1-7, and

Figure 1-9 for locations.

1-13

Module Details

The SRP module provides standard craft management interfaces,
including:

• 10/100Base-T – Enables access to the E-series router for Ethernet

management functions via CLI or SNMP, for example.

• RS-232 – Provides a serial connection for monitoring the system’s

hardware configuration through a PC (running terminal emulation
software) or ASCII terminal. Allows direct CLI access.

• Alarm contacts – Provide for remote indication of critical, major, and

minor E-series router alarms (ERX-7xx/14xx models only; currently
not implemented)

• External timing inputs – Provide a method of ensuring that the clock

timing used by the E-series router remains synchronized with the
network’s system clock. BNC connectors and wire wraps are available
for ERX-7xx/14xx models only.

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 f ields (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.

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 Chapter 12, Module Specifications. See Figure 1-5, Figure 1-7, and

Figure 1-9 for locations. For details about installing I/O modules, see

Chapter 5, Installing Modules.

1-15

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 the E-Series

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 E-Series

System Basics Configuration Guide, Chapter 3, Configuring SNMP.

CHAPTER 1

1-16

E-Series Overview

NMC-RX Device Management System

The NMX-RX application provides a global method of managing all
routers, line modules, and ports through a graphical user interface.

Redundancy Features

The system has the following redundancy features:

SRP Modules

Note: This section applies to ERX-7xx/14xx models only. ERX-310 routers contain
one SRP module and therefore do not offer SRP module redundancy.

ERX-7xx/14xx models use a 1:1 redundancy scheme for the SRP module.
When two SRP modules of the same type are installed in the chassis, one
acts as a primary and the second as a standby. Both SRP modules share a
single 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. (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 the E-Series

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 5, Installing 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 5,

Installing 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

Redundancy Features

E-Series Routers

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.

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

Line Modules

Note: This section applies to ERX-7xx/14xx models only. ERX-310 routers do not
offer line module redundancy.

ERX-7xx/14xx models support line module redundancy for several line
modules. For details about which line modules support redundancy, see

Chapter 12, Module Specifications. In this scheme, an extra line module

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

• Spare line module

• Redundancy midplane

• Redundancy I/O module

A redundancy midplane may cover 3–6 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.

CHAPTER 1

1-18

E-Series Overview

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 1-15 shows the data f low when a spare line module becomes

active.

E-Series Routers

For information about installing modules for line module redundancy, see

Chapter 5, Installing Modules. For information about configuring and

managing SRP module redundancy, see E-Series System Basics

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

All E-series routers provide a power architecture that distributes
redundant –48 VDC feeds through the router to each line module, SRP
module, and fan module where DC-to-DC converters provide local
conversion to the required secondary voltages.

The ERX-310 router is available with either DC or AC power inputs. The
AC-powered version can be configured with one or two hot-swappable
power supplies for optional redundancy (see Figure 1-8 and Figure 1-9).
The power supplies convert AC power to internal –48 V redundant DC
feeds that are then distributed through the router.

Forced air-cooling keeps the temperature of the E-series modules and
components within normal operating limits. In ERX-14xx models, six
cooling fans are located in a tray at the top of the router (see Figure 1-4).
In ERX-7xx models, four cooling fans are located in a tray on one side of
the router (see Figure 1-6). In the ERX-310 router, two cooling fans are
located in a tray on one side of the router (see Figure 1-8).

1-19

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 10, Troubleshooting.

In ERX-7xx/14xx models, the fan tray has two redundant converters that
power the fans (for the ERX-14xx models, a –24 V, 50 W converter; for
the ERX-7xx models, a –12 V, 15 W converter). If one converter fails, the
other takes over. The ERX-310 router does not have redundant
converters.

For all E-series routers, the system software reports an alarm if any of the
fans or converters fail.

Rack-Mounted Installation

Juniper Networks recommends that you use a standard EIA distribution
rack. Refer to Equipment Rack Requirements in Chapter 3, Installation

Guidelines and Requirements, for detailed rack information.

Installation Guidelines

Before installing the systems in a rack, consider the following guidelines
and refer to Figure 4-2:

• You c a n in s ta l l up to t h ree ERX-14 xx models, six ERX-7xx models, or

fourteen ERX-310 routers in a single 7-ft. (2.1 m) rack.

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

• You can install an ERX-14xx model, an ERX-7xx model, and an

ERX-310 router together in the same rack (see Figure 4-2).

If you install an ERX-7xx model or ERX-310 router directly above an
ERX-14xx model in the same rack, you must install a plenum between
the ERX-7xx model or ERX-310 router and the ERX-14xx model so
that the air can circulate between the systems (see Figure 3-2). This
plenum is available from Juniper Networks.

Rack-Mounted Installation

E-Series Routers

4-3

If you install an ERX-14xx model above an ERX-7xx model or
ERX-310 router, there is no need to install a plenum between the units
because the ERX-7xx models and ERX-310 routers vent air out the
side of the chassis.

Warning: To maintain airflow requirements, a plenum must be installed above
an ERX-14xx model before any other piece of equipment is installed above the
router.

• Install heavier systems, such as an ERX-14xx model, on the bottom of

the rack. Lighter systems, such as the ERX-310 router, should be
mounted higher in the rack.

Installing E-Series Routers

Installing the Router

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

• A Phillips screwdriver

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

(provided with the router ) for each router to be installed

Warning: Three people are required to install the E-series router in a rack: two to
lift the system into position and one to screw it to the rack.

Note: All persons handling an E-series router should wear an antistatic device.

To install the router in the rack:

1 Position the router in its designated location in the equipment rack.

Make sure the holes of the mounting brackets align evenly with the
holes of the equipment rack on both sides.

Note: One person should stand on the left side of the router, and another should
stand on the right side when lifting.

2 Starting at the bottom, secure the router in the equipment rack by

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

An OC48 line module spans two slots in an ERX-1440 router. You can
install this line module only in slots 2–3 and slots 4–5. Other slots in the
system do not support this line module.

The corresponding OC48 Frame APS I/O module spans only one slot.
Install the I/O module in the lower of the slots (either slot 2 or slot 4) that
the line module spans.

Replacing and Managing Modules Using the Software

For information about software procedures associated with replacing and
managing modules, see E-Series System Basics Configuration Guide,

Chapter 5, Managing Line Modules and SRP Modules.

Hot-Swapping Modules

All E-series routers support hot-swapping of modules. Hot-swapping
allows you to add or remove a module without powering down the
system.

Protecting Modules and Slots

Each E-series chassis has an ESD (electrostatic discharge) grounding jack.
See Table 5 -1 for locations. To prevent damage from electrostatic
discharge, connect an antistatic wrist strap to the jack when handling
components.

Installing Modules

Order of Installation

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

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

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

Caution: If you meet strong resistance when attempting to seat the module using
the ejectors, remove it from the chassis and confirm that the slot is one designed to
hold the module. Also, be sure that you have aligned the top and bottom edges in
the correct matching tracks.

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

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

Before you attempt to install or replace a module (inserted in the front of
the chassis), the corresponding I/O module (inserted in the rear of the
chassis) should already be in place. The system diagnostics run when a
module is installed in a chassis slot. If the corresponding I/O module is
not present, the diagnostics fail, and you need to remove and reinsert the
module.

Required Tools and Safety Items

You need the following tools to install a line module:

• A Phillips screwdriver

• An ESD wrist strap

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 E-series router,
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.

Installing Components for Line Module Redundancy

Installing Components for Line Module Redundancy

A spare line module provides redundancy for a group of identical line
modules for ERX-7xx/14xx models only.

Note: The ERX-310 router does not support line module redundancy.

For line module redundancy to operate, you must install:

• The line modules, including the spare line module

• The redundancy midplane

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

For more information, see Redundancy Features in Chapter 1, E-Series

Overview.

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

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

5-13

E-Series Routers

Installing the Line Modules

To install the line modules in a redundancy group:

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

redundancy group.

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

Line and I/O Modules 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 E-Series System Basics Configuration Guide, Chapter 5,

Managing Line Modules and SRP Modules for information about

the halt command.

CHAPTER 5

5-14

Installing Modules

Warning: Turn off the E-series router before you install the redundancy midplane.
Working inside the router 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 5-7).

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 5-7).

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.

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

redundancy midplane is aligned correctly; then tighten the screws.

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

Required Tools, Wires, and Cables

Cabling your system should take only a few minutes. You will need the
items listed below and in Table 6-1 for proper installation.

• 1/8" flathead screwdriver

• 3/8" wrench or 3/8" nut-driver

• No. 2 Phillips screwdriver

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

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

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

• Power input module wiring – We recommend a minimum of 10-AWG

(ERX-7xx/14xx model) or 14-AWG (ERX-310 router DC model) wire
with a dual stud terminal lug with 3/8" spacing. For the ERX-310

Note: If you plan on using a cable-management bracket (ERX-7xx/14xx models
only), install it before you begin cabling your E-series router. Cable-management
brackets are helpful to keep network interface cables untangled and orderly and to
prevent cables from hindering access to other slots. See Installing a

Cable-Management Bracket on ERX-7xx Models in Chapter 9, Maintaining
E-Series Routers.

Cabling the SRP I/O Module

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

When connecting a console directly to the SRP I/O module, use a cable
appropriate for your terminal connector. The cable must have a female
DB-9 connector to attach to the RS-232 port on the SRP I/O module.
See Figure 6-2 and Figure 6-3.

The console port is considered a data terminal equipment interface
(DTE). Direct connection to a terminal or PC (which also have DTE
interfaces) requires a crossover cable.

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

Only ERX-7xx/14xx models have external timing ports and alarm leads
located on the SRP I/O module. All E-series routers have console ports
located on the SRP I/O module. See Table 6 -2 for details on each
component.

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

Note: This section applies to all E-series routers.

6-7

There are two ports located in the Console section of the SRP I/O
module (see Figure 6-2 and Figure 6-3) that allow management access.

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

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

• The RS-232 port accepts a DB-9 (female) connector, allowing

direct CLI access from a console terminal.

The console port is considered a data terminal equipment
interface (DTE). Direct connection to a terminal or PC (which
also have DTE interfaces) requires a crossover cable.

Connecting to the Network

To connect the E-series router to the network:

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

(RJ-45) port on the SRP I/O module until it clicks into place.

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

network for an out-of-band connection.

Connecting to a Console Terminal

When you connect a console directly to the E-series router SRP I/O
module, use a cable appropriate for your terminal connector. The cable
must have a female DB-9 connector to attach to the RS-232 port on the
SRP I/O module.

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

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

the screws.

2 Connect the other end of the cable to your terminal’s serial port

(VT100/ANSI).

Cabling the E-Series Router for Power

After you have correctly cabled the modules and I/O modules, you must
attach grounding and electrical wires before you attempt system
power-up. There are three main tasks involved:

1 Switch all E-series router power switches to OFF.

Caution: Switches may have inadvertently flipped to ON during shipping and
installation.

2 Connect the grounding wires to the chassis.

Warning: Always connect the grounding wires first (before connecting the power
cables) and disconnect them last when installing or servicing the E-series router.

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

See Chapter 11, System Specifications for the power requirements for the
E-series router. Table 6 -3 identifies the power input module cabling
requirements, and Figure 6-4 shows the main components of a power

Task 1: Turn Off All E-Series Router Power

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

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

Task 2: Connect the Grounding Cables

All E-series routers have two grounding studs located in the rear of the
chassis, near the power inputs. Each stud provides grounding for a single
power unit.

To ground each power unit:

1 Locate the grounding studs on the E-series router (see Figure 6-4 and

Figure 6-5).

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

Note: We recommend a minimum of 10-AWG ground wire with a ring style
terminal.

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

tighten the nuts to secure the connection.

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

ground termination lead.

Cabling E-Series Routers

Warning: The wiring color code of the power cables depends on the color coding
of the DC power source installed at your site. Color code standards for DC wiring
do not exist. To ensure that the correct polarity is connected to the E-series router
power units, confirm the connection of the power cables to the + (positive) and
– (negative) leads at the power source.

3 Remove the nuts and locking washers from the posts for the power

input (A or B) using a small insulated adjustable wrench.

4 Place one negative (neutral) cable lead on the post labeled –48 VDC.

5 Replace the locking washers and nuts, and tighten the nuts to secure

the connection.

6 Place the other cable lead on the post labeled RTN.

7 Replace the locking washer and nut, and tighten the nut to secure

the connection.

8 Attach the opposite end of Power A’s wire leads to the appropriate

leads on your power source.

Note: To provide redundancy, Power A and Power B leads should not terminate at
the same power source.

Redundant Ports

The Next Step

Some modules have redundant ports. See Chapter 12, Module

Specifications for specifications. Cabling both ports provides a redundant

path to the E-series 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 E-series GE I/O
module must use the same type of SFP.

Warning: Be sure the power source is turned off and the system is turned off
before performing the following task.

Connect DC power or AC power to your E-series router.
(depending on model)

Cable all line modules. 6-14

Note: This procedure assumes that the system is already connected to a power
source. See Chapter 6, Cabling the E-Series Router for Power.

6-9

For specifications on the electrical requirements for the system, see

Chapter 11, System Specifications. For details on the power consumed by

the different E-series modules, see Chapter 12, Module Specifications.

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

To p owe r u p t h e sy s t e m :

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

2 Inspect all grounding and power connections to the E-series chassis.

3 Confirm that all connections are secure.

4 Switch the power switches to ON.

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

system is booting properly. See Tabl e 10-2 in Chapter 10,

Tro u b le s hooting. for LED status explanations.

When the prompt appears on the system console, the system is in
User Exec mode and is ready to be configured:

host1>

6 Enter the enable command to access Privileged Exec mode:

host1>enable

host1#

In Privileged Exec mode you can begin to configure the system. See
the E-Series System Basics Configuration Guide, Chapter 2,

Command Line Interface for more information.

Initialization Sequence

Each E-series line module is initialized independently. As a result, the
CLI on the SRP module may become available before the line modules
have completed initialization. Commands relating to a line module may
fail if the module has not completed initialization. The show version
command can be used to display line module status. Do not enter
commands for a line module until its state is “online”.

Status LEDs

Upon initial powerup, the components of the E-series router run boot
code, go through a series of self diagnostic tests, and synchronize with
each other.

When the tests are complete, use the LEDs on each module to determine
the status of the router. Observe the line module and SRP module LEDs
in the front, and the I/O line module and SRP I/O module LEDs in the
rear.

Refer to Chapter 10, Troubleshooting, for information on the system’s
LEDs.

Powering Down

The Next Step

If you need to power down or remove the SRP module, first enter the
halt command to temporarily suspend the system’s operation. See

E-Series System Basics Configuration Guide, Chapter 4, Managing the
System for more information.

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

If you shut down the system improperly, it will run an investigation of the
file allocation table (FAT) the next time it reboots.

If you have problems powering up the system, turn to Chapter 10,

Troubleshooting, for help.

If the system boots properly, turn to Chapter 8, Accessing E-Series

Routers.
