Configuring, Maintaining, and Monitoring Unison Locally
Each Main Hub, Expansion Hub, and RAU in the system constantly monitors itself
and its downstream units for internal fault and warning conditions. The results of this
monitoring are stored in memory and compared against new results.
The Expansion Hubs monitor their RAUs and store their status in memory. The Main
Hub monitors its Expansion Hubs and stores their status and the status of the RAUs in
its memory. When a unit detects a change in status, a fault or warning is reported.
Faults are indicated locally by red status LEDs, and both faults and warnings are
reported to the Main Hub and displayed on a PC/laptop, using the Main Hub’s serial
port, that is running the AdminManager software. Passive antennas connected to the
RAUs are not monitored automatically. Perform the System Test in order to retrieve
status information about antennas.
Using AdminManager locally, you can install a new system or new components,
change system parameters, and query system status. Figure 2-3 illustrates how the
system reports its status to AdminManager.

Hub
The Main Hub checks its own status and queries each
Expansion Hub for its status, which includes RAU status.
The Expansion Hub queries its own status
and polls each RAU for its status.
Each RAU passes its status to
the Expansion Hub.
• If a fault is detected, the
ALARM
LED is red. If no fault
is detected, the LED is green.
The Expansion Hub queries status
of each RAU and compares it to
previously stored status.
• If a fault is detected, LEDs on
the front panel turn red.
The Main Hub queries
status of each Expansion Hub
and each RAU and compares
it to previously stored status.
• If a fault is detected, LEDs
