Fans thermal switch
The intervention of the digital fan thermal protection is blocked for the correctly used fan.
If another fan is available it will be selected depending on the policy (Fn11) and immediately activated. The
contemporaneous intervention of the thermal protections of all of the digital fans causes an alarm which blocks the
machine.
In the case of fans with continuous control or digital fans in which a single common thermal fan has been configured,
the tripping of the thermal switch causes the machine to shut down.
