Platform Considerations

Procedures for managing modules vary depending on the type of E Series router that
you have. The following sections describe the types of modules that you can manage
for each type of E Series router and the general software procedures associated with
them.

ERX7xx Models, ERX14xx Models, and the ERX310 Broadband Services Router

You can manage line modules, I/O modules, and SRP modules on ERX7xx models,
ERX14xx models, and the ERX310 router. For more information about these modules,
see the ERX Module Guide.
For information about upgrading software on SRP modules, see "Installing JUNOSe
Software" on page 125. For information about related procedures and installing
modules, see ERX Hardware Guide, Chapter 4, Installing Modules.

Line Modules and I/O Modules

Most line modules available with these E Series models pair with a corresponding
I/O module; however, some line modules do not require a corresponding I/O module.
For example, the Service Module (SM) does not have a corresponding I/O module.
By configuring the performance line rate for a line module in the Juniper Networks
ERX705 , ERX710, and ERX1410 Broadband Services Routers, you can 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. For more information, see
"Configuring Performance Rate of Line Modules on ERX7xx Models and the ERX1410
Router" on page 373.
The Juniper Networks ERX1440 Broadband Services Router has two turbo slots
(numbered 2 and 4). You can install certain line modules in the turbo slots to achieve
greater line rate performance than when the modules are installed in other slots. For
more information, see JUNOSe Physical Layer Configuration Guide.
Redundancy is supported for some line modules on these models. For more
information, see SRP Module Redundancy in JUNOSe Service Availability Guide.
For more information about interface types and specifiers for ERX7xx models,
ERX14xx models, and the ERX310 router, see Interface Types and Specifiers in
JUNOSe Command Reference Guide.

SRP Modules

If you want to configure the performance line rate for a line module on supported
routers, you must consider the bandwidth requirements of the SRP module that is
installed on the router. For more information, see "Configuring Performance Rate
of Line Modules on ERX7xx Models and the ERX1410 Router" on page 373 .
Redundancy is supported for SRP modules on certain E Series routers; for more
information, see SRP Module Redundancy in JUNOSe Service Availability Guide.
