Shutdown criteria

     This is the time in seconds that the system waits following failure of AC power before initiating the system-shutdown procedure.
This value must be selected to provide users with enough time to close their applications and disconnect, but within the battery backup time provided by the UPS.
See the UPS manual for information on the backup time.
     If another criterion occurs before the end of the shutdown timer, the shutdown procedure is immediately run.

Possible values :  0 to 999999
Default value     :  this criterion for system shutdown is not enabled
Unit                     :  second
