The ERX310 router is a low-end platform that supports all of the same services as the
ERX7xx and ERX14xx models, but with smaller capacity and scaling capabilities. Like the
ERX7xx and ERX14xx models, the ERX310 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 ERX routers. The ERX310 router is designed to be
used as a small distributed POP router as well as a high-end CPE router.
The ERX310 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), as well as a select number of combination cards. The combination cards
provide a fixed combination of interfaces on the I/O module so that a single slot can
support multiple interfaces (ATM OC3 and GE, for example).
NOTE: The 10-Gbps SRP module used in the ERX310 router is different from
the 10-Gbps SRP module used in the ERX7xx and ERX14xx models. See "SRP
Module" on page 9 for more information.
The ERX310 router is available in either redundant AC- or DC-powered models.
