System Event Log Messages for IPMI Systems 49
Power Supply Events
The power supply sensors monitor the functionality of the power supplies. These messages provide status
and warning information for power supplies for a particular system.
Table 3-5. Power Supply Events
Event Message Severity Cause
< Power Supply Sensor Name > power
supply sensor removed.
Critical This event is generated when the power supply
sensor is removed.
<
Power Supply Sensor Name > power
supply sensor AC recovered.
Information This event is generated when the power supply
has been replaced.
<
Power Supply Sensor Name > power
supply sensor returned to normal
state.
Information This event is generated when the power supply
that failed or removed was replaced and the
state has returned to normal.
<
Entity Name > PS Redundancy
sensor redundancy degraded.
Information Power supply redundancy is degraded if one of
the power supply sources is removed or failed.
<
Entity Name > PS Redundancy
sensor redundancy lost.
Critical Power supply redundancy is lost if only one
power supply is functional.
<
Entity Name > PS Redundancy
sensor redundancy regained.
Information This event is generated if the power supply has
been reconnected or replaced.
<Power Supply Sensor Name>
predictive failure was asserted
Warning This event is generated when the power supply
is about to fail.
<Power Supply Sensor Name> input
lost was asserted
Critical This event is generated when the power supply
is unplugged.
<Power Supply Sensor Name>
predictive failure was deasserted
Information This event is generated when the power
supply has recovered from an earlier predictive
failure event.
<Power Supply Sensor Name> input
lost was deasserted
Information This event is generated when the power supply
is plugged in.
