Alarm Log

This menu provides a list of the last 200 alarms that have occurred on the MX2800. When the

alarm log becomes full, new alarms replace the oldest alarms in a first-in, first-out sequence.

The alarm log is periodically stored in nonvolatile memory. Once every minute, if an alarm has

been recorded or if the alarm log has been reset since the last time it was saved, then the

alarm log and system configuration are saved to nonvolatile memory. Both the alarm log and

system configuration are saved manually when the user executes the Save Configuration &

Alarm Log menu function in the

Configuration menu. Each time the system powers up, the

alarm log is retrieved from non-volatile memory.

A Reset Alarm Log function is accessible from the alarm log menu. This option clears the

alarm log. See Figure 5-19.
