AT-SBxFAN06 Module
The AT-SBxFAN06 Module is the cooling unit for the chassis. Refer to
Figure 26. It is a field- replaceable assembly that is installed in the AT-
SBx8106 Chassis at the factory.
The fan speeds are automatically controlled by the AT-SBx81CFC400
Controller Fabric Card, according to the internal operating temperature of
the unit. The fans are at their lowest speed when the ambient temperature
entering the chassis is approximately 20° C. The fan speeds increase to
provide additional cooling as the ambient temperature rises.
