5.2.2Backing Up the Alarm Log (Service Terminal Interface only)

The alarm log is stored as a file in the Liebert AC4; it can hold no more than 99 records. When the log is full, the oldest records are deleted from the end of the file as new alarm records are added at the beginning.

You may back up the alarm log file to a remote computer using the Service Terminal Interface, as described in 6.2 Back Up Log Files (Service Terminal Interface only).

To delete all records in the alarm log, see 7.10 Clear Alarms & Logs.
