ERX 11.1.x Hardware Guide

ERX7xx Models

NOTE: In the E Series documentation, the term ERX7xx models refers to both the
ERX705 and ERX710 routers. The terms ERX705 and ERX710 routers refer to the
specific models. See Figure 3 on page 6 and Figure 4 on page 7.
The ERX7xx models are robust, high-density routers with less capacity than the
ERX14xx models. The ERX7xx models use either the SRP-10G module or the SRP-5G
module.
You can configure the ERX7xx models to enable the line modules (LM) to operate
either at full line rate performance or at a rate dependent on the resources available.
For information about configuring performance of line modules, see JUNOSe System
Basics Configuration Guide, Chapter 6, Managing Modules.
NOTE: The 10-Gbps SRP module used in the ERX310 router is different from the
10-Gbps SRP module used in the ERX710 router. See "SRP Module" on page 9 for
more information.
The ERX705 chassis is the same as the ERX710 chassis. (See Figure 3 on page 6
and Figure 4 on page 7.) The chassis contains seven slots to accommodate modules.
Installation procedures and operating procedures are identical for both systems. All
ERX7xx and ERX14xx models use the same SRP I/O module, but different power
input modules are used.
NOTE: The router may look different from the routers shown in the figures in this
chapter, depending on the line modules in the slots.
