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, the alarm log and system
configuration are saved to nonvolatile memory. When executed, both the alarm log and system configura-
tion are saved manually by the Save Configuration & Alarm Log function (refer to
Alarm Log on page 3-43). 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 5-15.
