The blower module draws cooling air in through both card cages and the power supply bay to maintain acceptable operating temperatures for the internal components. The blower module is a sheet metal enclosure containing three fans, a controller card, and two faceplate LEDs. The blower module slides into and out the front of the frame on two rails attached to the frame. The blower module is secured to the frame with two captive screws. Electrical connections between the blower module and the system are made through a connector at the back of the blower module.
