The UPS output power will turn off in a number of
seconds equal to upsControlOutputOffTrapDelay.

The ups inverter is unavailable or malfunctioning due to an internal failure.

This trap is sent to the trap receivers to check proper reception of traps.

The ups has gone on bypass for some reason.

The ups bypass is unavailable

The ups output is switched off.

The ups input power is incorrect in voltage,
frequency, or phase rotation.

One of the defined building alarms has occurred.

The ups shutdown imminent alarm has occurred.

The ups is returned to utility power running the inverter 
after either a transfer to bypass or a run on battery.

The UPS output power will turn on in a number of
seconds equal to upsControlOutputOnTrapDelay.

One of the UPS breakers or contactors has been opened.

An alarm not defined in the xups Well Known Alarms
(eg, an alarm defined in RFC1628)
has been added to the Alarm Table.

An alarm not defined in the xups Well Known Alarms
has been removed from the Alarm Table.

One or more batteries have been determined to require replacement.

The UPS has shutdown as requested, i.e., the output is off.

The result of the last diagnostic test indicates a failure.

A problem has been encountered in the communications
between the agent and the UPS.

An xupsControlOutputOffDelay countdown is underway.

A test is in progress, as initiated and indicated by the xupsTest Group.  
When the test is complete, one of the following traps will be sent:
- xupstdDiagnosticTestFailed if the test fails,
- xupstdDiagnosticTestPassed on success, or
- xupstdAlarmEntryRemoved in other cases (e.g., Test Canceled).

The ambient temperature, xupsEnvAmbientTemp, has fallen below 
the set lower limit, xupsEnvAmbientLowerLimit, or has risen above 
the set upper limit, xupsEnvAmbientUpperLimit.

The UPS has no AC input power and is running on 
battery.

The Contact indicated by xupsContactIndex is in its Active state.
The following are the situations that generate this trap:
   For xupsContactType:    and     xupsContactState: 
       normallyOpen(1)     and     closedWithNotice(4)
       normallyClosed(2)   and     openWithNotice(3)
       anyChange(3)        and     openWithNotice(3) or closedWithNotice(4)

The Contact indicated by xupsContactIndex has changed to its Inactive state.

A parallel UPS system is no longer operating in N+1 redundant mode;
this may be due to module failure or removal, or due to overloading.

An internal temperature is out of tolerance.

An uncorrected problem has been detected within the UPS charger subsystem.

The failure of one or more fans in the UPS has been detected.

The failure of one or more fuses has been detected.

A Relay, Contactor, or Breaker has failed.

One module in a parallel or composite system has failed.

The system is being powered by its Alternate Power Source, such as a 
Secondary utility feed (on a dual AC input UPS), generator, flywheel, 
or fuel cell.

The UPS batteries are low.  Tied to low battery 
alarm condition.

On systems with a separate alternate power source (eg, dual AC inputs), 
that alternate power source is currently not available.  This could be 
a problem if the primary power source (eg, utility) fails for a period 
of time longer than that for which the internal batteries can supply power.

Some Notice condition exists which is not covered by the other traps.
This is like an xupstdInternalFailure, but at a lower severity level.

The remote temperature, xupsEnvRemoteTemp, has fallen below 
the set lower limit, xupsEnvRemoteTempLowerLimit, or has risen above 
the set upper limit, xupsEnvRemoteTempUpperLimit.

The remote temperature, xupsEnvRemoteHumidity, has fallen below 
the set lower limit, xupsEnvRemoteHumidityLowerLimit, or has risen above 
the set upper limit, xupsEnvRemoteHumidityUpperLimit.

A periodic status trap message.  It is sent at an interval
set by object xupsHeartbeatMinsInterval.
The included variables provide a brief statement of the UPS status.

A diagnostic test just completed, and its result is Passed.
The included variables provide additional information on the test.

The output condition (other than OutputOverload) is out of tolerance.

The UPS output is off and the UPS is awaiting the return of input power.

The UPS has been placed on Maintenance / Manual Bypass by an operator.

This trap is sent when the SNMP agent first establishes a communication 
link with the UPS.
The included variables provide identification and UPS status information.

Input power has been restored after running on battery.

This trap is sent when the SNMP agent is exiting or closing down gracefully.
This may be triggered by a signal from the OS to stop this process.  In many
implementations, it will be followed quickly by a restart of this vital process.

The ups output is not protectet for any reason in the UPS.

The battery has recovered from a low battery condition.

The ups has sensed an overload of greater than 
106 percent.  Tied to the 106% overload alarm.

Some component of the ups - rectifier, inverter,
control panel has failed.  Tied to alarms indi-
cating failure.

The Battery Totally Discharged Alarm has occurred.
