Alarms and Performance

Alarms and Performance

The MGX 8260 Media Gateway notifies maintenance or operations personnel about equipment alarms at several levels:

You can view the event log for informational notices about changes in the system. For example, inserting a new card adds an event to the log.

The WebViewer displays the most severe alarm in the upper right corner of every screen (see Figure 6-1).


Figure 6-1: Chassis View with Alarms


The alarm indicator is a rectangular icon that is green for normal operation and flashes red or yellow for alarm conditions.

You can obtain more information about the alarm by clicking the alarm indicator. The chassis view also shows a graphical representation of the front panel, including alarm indications for each card. To obtain more information about a specific card, click the corresponding Card or Line indicator.
