The FDDILink module has three LEDs: One indicates the status of the whole
FDDILink module and the other two indicate the status of the physical fiber
connection to each transceiver. The A STATUS LED corresponds to the left
transceiver, and the B STATUS LED corresponds to the right transceiver. Table 2-2
explains the LED states.
