E-series Routers ! 9
Chapter 1: E-series Overview
ERX-310 Router
The ERX-310 router is a low-end platform that supports all of the same services as
the ERX-7xx/14xx models, but with smaller capacity and scaling capabilities. Like
the ERX-7xx/14xx models, the ERX-310 router uses the same software architecture,
providing a single IP entry point into the network with the same IP-based protocols
and services that are available on other E-series routers. The ERX-310 router is
designed to be used as a small distributed POP router as well as a high-end CPE
router.
The ERX-310 router is a three-slot chassis with a midplane architecture. One slot
supports one nonredundant 10-Gbps SRP module, while the other two slots support
line modules. The router supports existing E-series ASIC-based line modules (except
the OC48/STM16 line module).
The ERX-310 router is available in either redundant AC- or DC-powered models.

NOTE: The 10-Gbps SRP module used in the ERX-310 router is different from the
10-Gbps SRP module used in the ERX-7xx/14xx models. See section SRP Module,
later in this chapter, for more information.
