Description
Indicates the individual fan module is present. After the hardware senses the fan module, software
ensures the airflow is consistent with the other fan modules and that it is functioning correctly.
Indicates one of the following:
The fan module is not present.
The fan module is not functioning normally.
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.
