Front Cooling Fan Control Board
The front cooling fans' main purpose is to cool the hard disk drives. These
fans also have a fan control board like the rear cooling fans. The front cool-
ing 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 shows
the power, activity, and status of each hard disk drive.
