ERX System Modules

The system supports an SRP module and a selection of line modules. You can use any line module for access or uplink. Access line modules receive traffic from low-speed circuits, and the system routes the traffic onto higher-speed uplink line modules and then to the core of the Internet.

Each module connects to a corresponding I/O module via a passive midplane. See Figure 1-7.

The front panel of each system module contains a collection of status LEDs (light-emitting diodes). See Figure 1-8. For information about how to interpret the LEDs, see Chapter 8, Troubleshooting.
