ERX-14xx Models
NOTE: In the E-s
eries 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 1 and Figure 2.
The ERX-1440 router manages a n extremely high volume of n etwork traffic,
and uses a 40-Gbps switch route processor (SRP) module, either the SRP-40G o r
SRP-40G+ modu
le. (The SRP-40G+ module obsoletes the SRP-40G module;
however, the software continues to support both modules.) In this model, all
line mo dules operate a t full wire speed simultaneously.
The E RX-1410 router manages high levels of network traffic, and uses the
10-Gbps SRP m
odule (SRP-10 G). You can configure the ERX-1410 router to
enable the line modu les either to operateatfulllinerateperformanceorto
allow line modules to operate at a rate dependent on the resources available.
The former o p
tion restricts the allowed combinations of line modules. For
information on co nfigu ring performanceoflinemodules,seeJUNOSe System
Basics Configuration Guide, Chapter 6, Managing 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 “SRP Module” on page 10
for more information.
Externally, the ERX-1440 chassis is the same as the ERX-1410 chassis. (See Figure 1
and Figure 2
.) Both routers contain 14 vertical slots to 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 bo th
systems. All ERX-7xx and ERX-14xx models use the same SRP I/O module,
but differ
ent power input m odules 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.
