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.
