STATUS current
DESCRIPTION
"A Fan notification is sent when the specified fan detects a
fault or clears a fault. The current ambient air temperature
entering the fan is reported in the aviciBayFanCurrTemp object.
All existing fan faults are reported in the
aviciBayFanCurrFailures object as a bitmap. If no failures
exist, this object contains a 0. A human readable description
of the event triggering this notification is included in the
aviciSysTrapDescr object.
Communication Failure: This failure indicates that the cooling
module has been removed or the cooling module firmware is no
longer communicating with the bay controller. If a
communication failure occurs, the fans will run in autonomous
mode until communication with the bay controller is
reestablished. Once communication is established, the failure
is cleared.
General Failure: This failure indicates that the cooling module
firmware is able to communicate with the bay controller and is
reporting a broken fan. This could mean that the fan is burned
out, jammed, or the firmware is unable to sense fan speed due to
tachometer failure. When the problem is corrected, the failure
is cleared.
Filter Blocked: This failure indicates that the fan detected
that the filter is blocked. When the obstruction is removed
from the filter or the clogged air filter is replaced, this
failure will clear.
Bad or absent internal thermistor: This failure indicates that
the fan internal thermistor is missing or is not functioning.
If the thermister is not functioning, the fan cannot sense the
incoming ambient air temperature. The ambient temperature is
used to control fan speed in autonomous mode and when there are
no modules reporting their current temperature.
Bad or absent external thermistor: This failure indicates that
the fan external thermistor is expected to be installed and is
not functioning.
Minor temperature threshold: This failure indicates that the
incoming ambient air temperature is above the minor threshold
temperature, but below the major threshold temperature. Either
the cooling system in the building has failed, or it has
insufficient cooling capacity for the equipment in the room.
A rapid rise in temperature usually indicates cooling system
failure whereas a slow rise usually indicates insufficient
cooling capacity. When the temperature drops below the minor
threshold, this failure will clear.
Major temperature threshold: This failure indicates that the
incoming ambient air temperature is above the major threshold
temperature, but below the critical threshold temperature.
Either the cooling system in the building has failed, or it has
insufficient cooling capacity for the equipment in the room.
A rapid rise in temperature usually indicates cooling system
failure whereas a slow rise usually indicates insufficient
cooling capacity. When the temperature drops below the major
threshold, this failure will clear.
Critical temperature threshold: This failure indicates that the
incoming ambient air temperature is above the critical threshold
temperature. Either the cooling system in the building has
failed, or it has insufficient cooling capacity for the
equipment in the room. A rapid rise in temperature usually
indicates cooling system failure whereas a slow rise usually
indicates insufficient cooling capacity. When the temperature
drops below the critical threshold, this failure will clear."
