• 4-10. Front Cooling Fans

The front cooling fan module consists of a control board, a hard disk drive LED status board, and two cooling fans. The message LED board mounted in the front of the cooling fan module consists of five sets of LEDs to represent the status of up to five hard disk drives. Each set has three LEDs which can show the power, activity, and status of each hard disk drive.

The front cooling fans’ main purpose is to cool the hard disk drives. These fans can be removed by using a small screw driver to push the eject mechanism in the fan module. The eject mechanism is behind a small hole as circled below. There are two individual 2 1/4 inch (6cm) fans secured by four screws on each fan. The ASMA software will report an error message when any of these two fans malfunctions.

Usually, the rotation of the fan sends air toward the manufacturer’s label on the center of the fan.
