ERX 11.1.x Hardware Guide

ERX14xx Models

NOTE: In the E Series documentation, the term ERX14xx models refers to both the
ERX1440 and ERX1410 routers. The terms ERX1440 and ERX1410 routers refer to
the specific models. See Figure 1 on page 5 and Figure 2 on page 5.
The ERX1440 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 ERX1410 router manages high levels of network traffic, and uses the 10-Gbps
SRP module (SRP-10G). You can configure the ERX1410 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 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 ERX1410 router. See "SRP Module" on page 9 for
more information.
Externally, the ERX1440 chassis is the same as the ERX1410 chassis. (See Figure 1
on page 5 and Figure 2 on page 5.) Both routers contain 14 vertical slots to
accommodate modules.
Internally, the ERX1440 chassis differs from the ERX1410 chassis, and includes a
special midplane for the 40-Gbps SRP module.
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.
