ERX-310 Router
The ERX-310 router is a low-end pla tform that supports all of the same service s
as the ERX-7xx
and ERX-14xx models, but with smaller capacity and scaling
capabilities. Like the ERX-7xx and ERX-14xx models, the ERX-310 router
uses the sam e software architecture, providing a single IP entry point into
the n etwork w
ith the same IP-based protocols and services that are ava ilable
on other E RX 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 suppo rts existing E-series ASI C-based line modules (except
the OC48/STM 16 line module), as well as a selec t num b er of com bination cards.
The c ombina
tion cards provide a fixed combination of interfaces on the I/O module
so that a single slot can suppo rt multiple interfaces (ATM OC3 and GE, for example).
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 and ERX-14xx models. See “SRP
Module” on pag e 10 for more information.
The ERX-310
router is available in either redundant AC- o r DC-powered models.
