Event Message Severity Cause
The <Sensor Name/ Location>
temperature is less than the lower critical
threshold.
Critical Temperature of the backplane, system
board, system inlet, or the carrier in the
specified system <Sensor Name/Location>
entered into critical state.
The <Sensor Name/ Location>
temperature is greater than the upper
warning threshold.
Warning Temperature of the backplane, system
board, system inlet, or the carrier in the
specified system <Sensor Name/Location>
entered into non-critical state.
The <Sensor Name/ Location>
temperature is greater than the upper
critical threshold.
Critical Temperature of the backplane, system
board, system inlet, or the carrier in the
specified system <Sensor Name/Location>
entered into critical state.
The <Sensor Name/ Location>
temperature is outside of range.
Critical Temperature of the backplane, system
board, system inlet, or the carrier in the
specified system <Sensor Name/Location>
is outside of normal operating range.
The <Sensor Name/ Location>
temperature is within range.
Information Temperature of the backplane, system
board, system inlet, or the carrier in the
specified system <Sensor Name/Location>
returned to a normal operating range.
Voltage Sensor Events
The voltage sensor event messages monitor the number of volts across critical components. These
messages provide status and warning information for voltage sensors for a particular chassis.

<Sensor Name/Location>
voltage sensor detected a
failure <Reading> where
<Sensor Name/Location> is
the entity that this
sensor is monitoring.
Reading is specified in
volts. For example, 3.860
V.
Critical The voltage of the monitored
device has exceeded the critical
threshold.
<Sensor Name/Location>
voltage sensor state
asserted.
Critical The voltage specified by <Sensor
Name/Location> is in critical
state.
<Sensor Name/Location>
voltage sensor state de-
asserted.
Information The voltage of a previously
reported <Sensor Name/
Location> is returned to normal
state.
