The AT-SBxFAN12 Module, shown in Figure 8, is the cooling unit for the

shipped with the AT-SBx8112 Chassis.
The module is controlled by the AT-SBx81CFC400 Controller Fabric Card.
The fan speeds are automatically adjusted according to the internal
operating temperature of the switch. The fans are at their lowest speed
when the ambient temperature coming into the fan is approximately 20° C.
