MX2800 M13 Multiplexer User Manual

This menu provides statistics regarding protection switches. The number of protection switches that occur 
within the particular time period are listed. See 

View performance parameter information for the network in one of the three time period selections. Infor-
mation in these fields is for the given time period since the last reset. When viewing the 24-Hour History 
statistics screen, use the 

L

EFT

and 

R

IGHT

arrow keys to scroll through all 96 15-minute intervals. Clearing 

protection switch alarm counts will clear the Excessive Switch State

if active.

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 

on page 5-15.
