Reference Guide
Event Message Severity Cause
specified in RPM. For example,
100 RPM.
<Sensor Name/Location> Fan
sensor returned to normal
state <Reading>.
Information The fan specied 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 specied <Sensor Name/
Location> fan may not be sucient to
provide enough cooling to the system.
<Sensor Name/Location> Fan
Redundancy sensor redundancy
degraded.
Information The fan specied 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 specied 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 specied 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 specied fan might not
provide enough cooling to the system.
Fan <number> RPM is less than
the lower critical threshold.
Critical The speed of the specied fan is not
sucient to provide enough cooling to the
system.
Fan <number> RPM is greater
than the upper warning
threshold.
Warning The speed of the specied fan exceeded
the warning threshold.
Fan <number> RPM is greater
than the upper critical
threshold.
Critical The speed of the specied fan exceeded
the critical threshold.
Fan <number> RPM is outside of
range.
Critical The speed of the specied fan might not
provide enough cooling to the system.
Fan <number> RPM is within
range.
Information The speed of the specied fan is operating
in a normal range.
Fan <number> is removed.
Critical A required fan was removed.
Fan <number> was inserted.
Information A fan was added.
Fan <number> is present.
Information The total number of fans present.
Fan <number> is absent.
Critical A required fan is missing.
The fans are redundant.
Information One or more fans may have started
functioning or installed and the redundancy
has been regained.
