• 4-2 Rear Cooling Fan Control Board

The rear fans are controlled and monitored by a control board. The fan con-

trol board requires power input from the power supply which allows the

individual fans to obtain their power when connected to the control board.

The ASMA software can monitor the fan status from the fan control board.

The fan control board’s cable connections are shown below.
