PRELIMINARY LED Indicators
Port LEDs
The Main Hub has one pair of fiber port LEDs for each of the four Expansion Hub
ports. The LED pairs can be in one of four states, as shown in the following table, in a
combination of the following:
off
steady green
steady red
The port LEDs indicate the status of the Expansion Hub and RAUs; however, they do
not indicate which particular unit is having a problem (i.e., the Expansion Hub vs.
one of the RAUs).
