Table 10-1 describes the meanings of fan indicators.

Table 10-1 Description of the fan module indicators

Indicator	Color	Description
STATUS	Off	The fan is not running.
	Green	Blinking slowly: The fan is working properly and communicating with the MPU normally. Blinking fast: The fan is working properly but not communicating with the MPU normally.
	Red	On: The fan is faulty and needs to be replaced. Blinking slowly: An alarm has been generated and needs to be handled. Possible causes of the alarm include errors of dual in-line package (DIP) switches, short-circuit, fan blades blocked, and fault of the fan module.
