Reference Attach Mechanism

The ALCT pump is attached to the motherboard through the use of a backside stiffener

plate. Prior to motherboard installation in the chassis the backside stiffener plate is

attached with two screws. Once installed these screws remain installed unless the

stiffener plate requires removal. After installation of the board into the chassis the

pump and upper structure are secured to the motherboard and backside stiffener with

two additional screws (Figure 18). The heat exchanger is positioned on the back

panel and is secured in place using four screws provided in the accessory kit. The

heat exchanger can be mounted on most back panels that will accept 120 mm fans.

The range of recommended positions of the heat exchanger relative to the pump is

defined in Figure 74.
