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 spe cific models. See Figure 1 and Figure 2.
The ERX-1440 router ma na ges an extremely high volume of network 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 modules operate at full wire speed simultaneously.
The E RX-1410 router manages high levels of network traffic, and uses the
10-Gbps SRP m
odule (SRP-10G). You can configure the ERX-1410 router to
enable the line modules either to operateatfulllinerateperformanceorto
allow line modules to operate at a rate dependent on the resources available.
The former op
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. Se e “SRP Module” on p age 10
for more information.
Externally, the ERX-1440 chassis is the same as the ERX-1410 chassis. (See Figure 1
and Figure 2
.) B oth routers contain 14 vertical slots to accommodate module s.
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 and ERX-14xx models u se the same SRP I/O module,
but differ
ent power input modules a re 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.
