DescriptionStateLED Color
The fan module is operating normally. The system has verified
that the module is engaged, that the airflow is in the correct
direction, and that the fan is operating correctly.
On steadilyGreen
An error has been detected in the fan module. Replace the fan
module as soon as possible. Either the fan has failed or it is
seated incorrectly. To maintain proper airflow through the
chassis, leave the fan module installed in the chassis until you
are ready to replace it.
On steadilyRed
Under normal operating conditions, the fan modules operate at a moderate speed. Temperature sensors
in the chassis monitor the temperature within the chassis.
The system raises an alarm if a fan module fails or if the ambient temperature inside the chassis rises above
the acceptable range. If the temperature inside the chassis rises above the threshold temperature, the
system shuts down automatically.
