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 ERX-705, ERX-710, and ERX-1410 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 ERX-7xx Models and the ERX-1410 Router.

The ERX-1440 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 Line Module Redundancy.

For more information about interface types and specifiers for ERX-7xx models, ERX-14xx models, and the ERX-310 router, see Interface Types and Specifiers.
