• Query system status
Refer to the AdminBrowser User Manual (D-620607-0-20) for information about
installing and using AdminBrowser software.
2.3.1 System Monitoring and Reporting
Each Fusion Main Hub in the system constantly monitors itself, its Expansion Hubs,
and their downstream RAUs for internal fault and warning conditions. The results of
this monitoring are stored in memory and compared against new results.
When a Main or Expansion Hub detects a change in status, it reports a fault or warn-
ing alarm. Faults are also indicated locally by red status LEDs. Both faults and warn-
ings are reported to AdminBrowser software and displayed on a PC/laptop connected
to the Main Hub’s RJ-45 port. Passive antennas connected to the RAUs are not moni-
tored automatically. Perform a System Test to retrieve status information about anten-
nas.
Using AdminBrowser, you can install a new system or new components, change sys-
tem parameters, and query system status. Figure 2-4 illustrates how the system
reports its status to AdminBrowser.

2.3.2 Using Alarm Contacts
You can connect the DB-9 female connector on the rear panel of the Fusion Main
Hub to a local base station or to a daisy-chained series of Fusion and/or FlexWave
Focus systems.
Each RAU passes its status to
the Hub.
If a fault is detected, the
ALARM LED is red. If no fault
is detected, the LED is green.
The Expansion Hub queries
the status of each RAU and
compares it to the previously
stored status.
If a fault is detected, LEDs on
the front panel turn red.
