AT-SBxFAN12 Module
The AT-SBxFAN12 Module is the cooling unit for the chassis. It is a field-
replaceable assembly that is factory installed and shipped with the AT-
SBx3112 Chassis.
The module is controlled by the AT-SBx31CFC960 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.
The fan speeds increase to provide additional cooling as the ambient
temperature rises.
