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
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
Guide, Chapter 5, Managing Line Modules and SRP
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
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
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.
