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 control board also sends fan status information to the LEDs located on
the front of the server and to the ASMA software. The fan control board's
cable connections are shown below.
