3.1.3 Hub LED Indicators
The unit’s front panel LEDs indicate faults and commanded or fault lockouts. The
LEDs do not indicate warnings or whether the system test has been performed. Only
use the LEDs to provide basic information or as a backup when you are not using
AdminManager.
Upon power up, the Hub goes through a five-second test to check the LED lamps.
During this time, the LEDs blink through the states shown in Table 3-1, letting you
visually verify that the LED lamps and the firmware are functioning properly.
The Hub will automatically send the program band command to all
connected RAUs. A mismatched band will cause an error message
to be displayed in AdminManager and the RAU will have a fault con-
dition.
NOTE: Refer to Section 8 for troubleshooting using the LEDs.
Status LEDs
The Hub status LEDs can be in one of the states shown in Table 3-1. These LEDs can
be:
steady green
steady red
blinking green/red (alternating green/red)
There is no off state when the unit’s power is on.
