ERX 11.3.x Hardware Guide
ERX14xx Models
4
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.
