Each crossbar fabric module connects to 8 switching modules and 2 supervisor
modules. In addition, each crossbar fabric module supports four 55 Gbps fabric
ports connected to each switching module and one 55 Gbps fabric port connected
to each supervisor module.
The fan modules cover the fabric modules in the back of the chassis. Fan module 1
must be removed to access fabric modules 1 and 2, fan module 2 must be removed
to access fabric modules 3 and 4, and fan module 3 must be removed to access
fabric modules 5 and 6.
The LEDs on the crossbar fabric modules indicate the status of the modules.
Table 6 describes the LEDs.
