Fans
Under normal operating conditions, the fans operate at a moderate speed to reduce
noise. Temperature sensors in the chassis monitor the temperature within the chassis.
If any fan fails or if the temperature inside the chassis rises above the threshold, the
switch raises an alarm and all functioning fans operate at a higher speed than normal.
If the temperature inside the chassis rises above the threshold, the switch shuts down
automatically.
