2.4.1 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 the
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 faults and warnings are reported
to the Main Hub and displayed on a PC/laptop, via the Main Hub’s serial port, that is
running the AdminManager software.
Using AdminManager locally, you can install a new system or new components,
change system parameters, and query system status. The following figure illustrates
how the system reports its status to AdminManager.

Hub
The Main Hub checks its own status and polls each of its
Expansion Hubs for their status, which includes RAU status.
The Expansion Hub checks its own status
and polls each of its RAUs for their status.
Each RAU reports 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.
If a fault or warning condition
is detected, the information is
passed to the Expansion
Hub.
The Expansion Hub
receives status from
each of its RAUs and compares
it to previously stored status.
LEDs on the front panel of the
Expansion Hub light red if a fault
is detected in itself or an RAU.
If a fault or warning condition is
detected in the Expansion Hub
or an RAU, the information is
passed to the Main Hub.
The Main Hub receives
status of the Expansion Hubs
and each of their RAUs, and
compares it to previously
stored status.
LEDs on the front panel of
the Main Hub light red if a
fault is detected in any unit.
If a fault or warning condi-
tion is detected in any unit,
the Main Hub reports it to
the AdminManager.
