This guide provides an overview and description of the line modules, switch route processor (SRP) modules, and I/O modules available for the following E-series routers: ERX-14xx models, ERX-7xx models, and the ERX-310 router.

Unless otherwise specified, all line modules pair with I/O modules to create a module combination. Each module combination provides particular capabilities and connections in an E-series router.

A release may support multiple versions of a module. For information, see Software Compatibility in JUNOSe System Basics Configuration Guide, Chapter 5, Managing Modules.

Table 1 lists the module combinations supported by E-series routers.

This book also contains two appendixes:

• Module Protocol Support
• Module LEDs
