MESSAGE
ups_mond: UPS <tty special file name> Low Battery Voltage -
requires repair
SEVERITY Critical. PowerTrust hardware has failed. PowerTrust power output is still on,
but the PowerTrust unit will not be able to protect the system against an AC
power failure, if one occurs.
MEANING The PowerTrust device configured as <tty special file name> informed the
UPS Monitor that the voltage output of its battery is too low. The PowerTrust
unit can no longer be relied upon to supply battery reserve power in the event
of an AC power failure.
CAUSE A hardware problem in the battery or battery charger circuitry, or elsewhere
in the PowerTrust unit, has caused the battery to fail to perform normally.
ACTION Call HP Service.
