CAUSE The specified UPS device reported that it detected an
input power failure. There has been an AC power failure
somewhere in the power path leading into the UPS. The
UPS has switched to its internal battery pack to supply
reserve power.
ACTION If the power failure is brief, not long enough to exhaust the
UPS battery, no action is needed. Otherwise, determine
what is causing the power loss and take action to restore
the power before the UPS battery becomes exhausted.

Mode". (UPSWRN 0035)

Power Bypass Mode" of operation. This should only occur
when an HP Customer Engineer is servicing the UPS and
intends to put the UPS into "Bypass Mode".
ACTION No action is needed if this message occurs during
Customer Engineer servicing of the UPS.If this message
occurs during normal system operation, there is probably
a hardware problem in the UPS. Call your HP service
representative.

the past, and now the AC input power has been restored.
If the UPS is operating correctly, it will now switch from
battery operation back to normal AC power operation.
ACTION No action is needed. The system automatically returns to
normal operation when all UPS devices (there may be one
or several UPS devices on a system) detect that normal AC
input power is present following a power loss at any UPS.
37 MESSAGE UPS LDEV ! reports "Low Battery Charge"
condition. (UPSWRN 0037)

ago and has been supplying reserve power from its battery.
