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.
