Viewing SWAN Concentrator Alarms
When you view events using the OSM or TSM Event Viewers, the subsystem name
(or, in rare cases, the subsystem number) is shown in the SSID column. Both allow you
to specify the date and time ranges of the events you want displayed; the logs (such as
$0 and $ZLOG) from which you want events displayed; and the subsystems from
which you want events displayed.
To learn more about the differences between the OSM Event Viewer and the TSM
Event Viewer, see the OSM Migration Guide.
Cause, effect, and recovery information for event messages is available in event
details within the event viewers and also in the Operator Messages Manual.
Viewing SWAN Concentrator Alarms
To view an alarm generated by a ServerNet wide area network (SWAN) concentrator,
use the OSM Service Connection or the TSM Service Application:
1. In either the tree pane or the view pane, click on the resource.
2. In the details pane, click the Alarms tab. Alarms for the selected resource appear
in the Alarms tab in the details pane.
3. In the Alarms tab in the details pane, right click on the alarm and select Details
from the menu. The Alarm Detail dialog box appears.
4. To display repair actions for the alarm, in the Alarm Detail dialog box, check Repair
Actions or Repair Steps (depending on your version of client software).
If you need more detailed information about how to recover from a specific alarm, see
