PRELIMINARY Monitoring and Maintaining Unison Remotely
2.4.2 Monitoring and Maintaining Unison Remotely
When monitoring the system remotely, any change of state within the system causes
the Main Hub to initiate an automatic call-out and report the system status to the
OpsConsole. If the host does not acknowledge the connection, the Main Hub issues
an automatic call-out every 15 minutes until an auto acknowledge or standard request
for status (initiated by the host) is received.
You can use AdminManager to query system status via a read-only Configuration &
Maintenance panel. You cannot change system parameters or configure system com-
ponents remotely with AdminManager. (Refer to Figure 2-1 on page 2-5.)
The following figure illustrates how the system reports its status to the OpsConsole.
Figure 2-3 Remote System Monitoring and Reporting
Refer to the OpsConsole User Guide, LGC Wireless part number 8701-10, for more
information about using the OpsConsole for system monitoring.
Expansion
Hub
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 RAU and compares
it to previously stored status.
• If a fault is detected, LEDs on
the front panel light red.
• If a fault or warning condition
is detected in the Expansion
Hub or an RAU, the informa-
tion is passed to the Main
Hub.
The Main Hub receives
status of Expansion Hub
and each RAU and com-
pares it to previously
stored status.
• If a fault is detected,
LEDs on the front panel
light red.
• If a fault or warning con-
dition is detected in any
unit, the Main Hub ini-
tiates a call to the
OpsConsole.
Use the OpsConsole to
remotely monitor and
maintain the system.
