The rear fans are controlled and monitored by a control board. The fan
control 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 con-
trol board’s cable connections are shown below.
