Description
If the indicator blinks (0.5 Hz), the fan module is
working properly, and the communication is normal.
If the indicator blinks (4 Hz), the fan module is working
properly, but the communication is abnormal.
If the indicator blinks (0.5 Hz), an alarm is generated,
but you cannot determine whether the fan module needs
to be replaced. It is recommended that you observe the
situation for a period of time.
If the indicator is steady red, the fan module is faulty
and you need to replace it.
