ERX-310 Router

E-series Overview

The ERX-310 router is a low-end platform that supports all of the same services as th

e 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 m odules (except the OC48/STM16 line module), as well a s a select number of combination cards. The combina

tion cards provide a fixed combination of interfaces on the I/O module

so that a single slot can support multiple interfaces (ATM OC3 and GE, for example).

NOTE: The 10-Gbps SRP module used in the ERX-310 router is d ifferent from the 10-Gbps SRP

module used in the ERX-7xx/14xx models. See section “SRP Module” on page 11for more information.

The system mo

nitors the temperature of each module. If the temperature of a module exceeds the maximum limit, the system immediately goes into thermal protection mode and the modules are powered off. The ERX system controller enters a low p

ower mode, keeps the modules in a power-off condition, and does not respond to any management interface commands. For information about troubleshooting high operating temperatures, see “Troubleshooting” on p age 99.

In ERX-7xx/14xx models, the fan tray has two redundant converters that power the fans (fo

r 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 con verters fail.

Installing E-series Router s

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

ce.

You can instal

l an ERX-14xx model, an ERX-7xx model, and an ERX-310

router together in the same rack (see Figure 18).

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 54). This plenum is available from Juniper Networks.

If you install an ERX-14xx model above an ERX-7xx m odel or ERX-310 router, there is no ne

ed 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 (or another ERX-14xx model) must be installed above an ERX-14xx model before any other piece of equipment i

s installed above the router.

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

er systems, such as the ERX-310 router, should be mounted

higher in the rack.

WARNING: Connect the E-series router or rack to ground (earth), and ensure that a reliable grounding path is maintained in the rack.

WARNING: Do not

work on the system or connect or disconnect cables during

lightning activity.

WARNING: Be sure circuit breakers for the power source are in the OFF position before attachi

WARNING: Before servicing the E-series router, turn off the power.

WARNING: Remove jewelry (including rings, necklaces, and watches) before

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

WARNING: The ER

Task 1: Tu rn 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 29 and Figure 30).

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

Console Port Setup

Using HyperTerminal

A console terminal (PC, Macintosh, or UNIX workstation) can be connected directly to the SRP I/O m

odule via the RS-232 terminal port. 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 Hyper

Terminal. 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.

Assigning an IP Address

When your console is ready to communicate with the system, power up the system (see “Powerin system. The system powers up in User Exec mode. To assign an IP address:

3. Continue to configure the system’s parameters as needed.

After you have assigned an IP address to the system, you can communicate remotely by running Telnet over an Ethernet network. See “Telnet Setup” on page 78.

When you have configured an IP address for the system, you can run Telnet from a host to access the system through its Ethernet port. To connect the
