Event Message Severity Cause
The <Sensor Name/Location>
voltage is outside of range.
Critical Voltage of the monitored Entity <Sensor
Name/ Location> is outside of normal
operating range.
The <Sensor Name/Location>
voltage is within range.
Information Voltage of the monitored Entity <Sensor
Name/ Location> returned to a normal
operating range.
Fan Sensor Events
The cooling device sensors monitor how well a fan is functioning. These messages provide status warning and failure messages for
fans for a particular chassis.
Table 7. Fan Sensor Events
Event Message Severity Cause
<Sensor Name/Location> Fan
sensor detected a failure
<Reading> where <Sensor Name/
Location> is the entity that
this sensor is monitoring.
For example "BMC Back Fan" or
"BMC Front Fan." Reading is
specified in RPM. For
example, 100 RPM.
Critical The speed of the specified <Sensor
Name/Location> fan is not sufficient to
provide enough cooling to the system.
<Sensor Name/Location> Fan
sensor returned to normal
state <Reading>.
Information The fan specified by <Sensor Name/
Location> has returned to its normal
operating speed.
<Sensor Name/Location> Fan
sensor detected a warning
<Reading>.
Warning The speed of the specified <Sensor
Name/Location> fan may not be
sufficient to provide enough cooling to
the system.
<Sensor Name/Location> Fan
Redundancy sensor redundancy
degraded.
Information The fan specified by <Sensor Name/
Location> may have failed and hence, the
redundancy has been degraded.
<Sensor Name/Location> Fan
Redundancy sensor redundancy
lost.
Critical The fan specified by <Sensor Name/
Location> may have failed and hence, the
redundancy that was degraded previously
has been lost.
<Sensor Name/Location> Fan
Redundancy sensor redundancy
regained
Information The fan specified by <Sensor Name/
Location> may have started functioning
again and hence, the redundancy has
been regained.
Fan <number> RPM is less than
the lower warning threshold.
Warning The speed of the specified fan might not
provide enough cooling to the system.
Fan <number> RPM is less than
the lower critical threshold.
Critical The speed of the specified fan is not
sufficient to provide enough cooling to
the system.
