overview of the topic, configuration tasks, and information about monitoring the
associated settings.
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.
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 117. 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 359.
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 Services Availability Configuration 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 359 .
