The messages in this section may precede a shutdown(1M) attempt, depending on the
particular PowerTrust configuration in the system.
MESSAGE
ups_mond: UPS <tty special file name> AC POWER FAILURE -
running on UPS battery
SEVERITY Warning. AC power failure. The PowerTrust unit is supplying battery reserve
power for up to a maximum of 15 minutes, or the configured shutdown delay.
After this, those UPSs configured as critical PowerTrust units will cause a
graceful shutdown of the system.
MEANING The PowerTrust device configured as <tty special filename> informed the UPS
Monitor that its AC input power has failed. The PowerTrust unit is now
supplying reserve power from its battery. Depending on the battery's state of
charge, there are from 0 to 15 minutes of full-load reserve power available
before the AC output from the PowerTrust unit shuts off.
CAUSE AC source power failure, detected by a PowerTrust unit.
ACTION Locate the AC power source for the PowerTrust unit reporting the power
failure, and try to restore power before the PowerTrust battery becomes
exhausted. If this is an isolated, brief power transient failure, no action is
needed; the system will recover automatically when AC power returns to
normal.
