E-Series Routers; Erx-14Xx Models - Juniper E Series Hardware Manual

E-series Routers

Five models of E-series routers are available:
All models use the same software. However, the specific model determines the:

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 4 and Figure 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 JUNOSe 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" on
page 11 for more information.
Externally, the ERX-1440 chassis is the same as the ERX-1410 chassis (see Figure 4
and Figure 5). Both routers contain 14 vertical slots to accommodate modules.
