E-Series Modules - Juniper E Series Hardware Manual

E-series 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 network.
Each module connects to a corresponding I/O module via a passive midplane. See
Figure 11.
The front panel of each module contains a collection of status LEDs (light-emitting
diodes). For information about how to interpret the LEDs, see Chapter 10,
Troubleshooting.
