Port LEDs
The Main Hub has one pair of fiber port LEDs for each of the four fiber optic ports.
The LED pairs can be in one of the states shown in Table 3-2. These LEDs can be:
off
steady green
steady red
blinking green/red (alternating green/red)
The port LEDs indicate the status of the Expansion Hub and RAUs; however, they do
not indicate which particular unit has a fault (i.e., the Expansion Hub vs. one of its
RAUs).
