Temperature, Fan etc.). The panel shows the current and latched statuses of these sub-alarms,
while the button shows the overall status of the SEM virtual alarm.
The button is red, indicating a problem with the SEM. But the status panel is all green,
indicating that the problem must come from another source. Here’s how to go about tracking
the problem down:
To track the problem
1. Right-click the SEM button, and then select Show status in GSM browser from the drop-
down menu.
The GSM Alarm browser window appears, with the virtual alarm highlighted (the GSM
running the SNMP plug-in instance for this particular SEM is also highlighted).
2. Click Edit plug-in.
The Build virtual alarm window appears, revealing the setup of the SEM virtual alarm,
including a list of its sub-alarms. In this case, the Primary GigE sub-alarm is red—this is the
likely source of the problem.
3. So far, we have only been looking at the SEM’s overall alarm. At this point, it might be useful
to look at the alarms for the device. The fastest way to do this is to return to the Web page
and right-click any one of the SEM sub-alarms, and then select Show status in GSM
browser from the drop-down menu.
The GSM Alarm browser window appears, with the sub-alarm highlighted inside the folder
containing all of the SEM’s sub-alarms. Looking a little further down the list, we can se the
Primary GigE sub-alarm is red.
4. Right-click the Primary GigE sub-alarm and click Properties.
The Alarm properties window appears. You can copy the URI for this alarm and use it to
search the Event and Incident Logs (see
"Searching the Event or Incident Log Database" ,
on page 142).
5. Assuming you are able to resolve the problem, you would observe the following changes
in iControl:
• The SEM alarm status on the Web page returns to normal (green).
• The Log Viewer displays a new entry reflecting the changed alarm status (returning
from error to normal).
• In the GSM Alarm Browser, the status of the SEM overall alarm and of the Primary GigE
sub-alarm return to normal (green).
• In iC Navigator, the status of the SEM overall alarm returns to normal (green).
