CONFIDENTIAL

Upon power up, the Main Hub goes through a 20-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. 
Upon completion of initialization, the LEDs stay in one of the first two states shown 
in Table 3-1.

The Main Hub automatically sends the program bands command to all connected 
RAUs. A mismatched band causes a fault message to be displayed in AdminBrowser 
and places the RAU in a disabled condition.

NOTE: Refer to Section 9.3.2 for troubleshooting using the LEDs.

NOTE: AdminBrowser should be used for troubleshooting the system. 
Only use LEDs for backup or confirmation. However, if there are communi-
cation problems within the system, the LEDs may provide additional infor-
mation that is not available using AdminBrowser.

The Main Hub has one pair of status LEDs, labeled 

 and 

, which can 

be in one of the states shown in Table 3-1. These LEDs can be:

steady green

steady red

off - no color (valid only during 90 second power cycle)

flashing red (60 ppm)

There is no off state when the unit’s power is on.
