Table 5-1 describes the mapping between switch models and FAN-031A series fan modules.

Common causes include short circuits, fan blades blocked, and faults of the fan module. The fan module has only one fan to cool the chassis.

FAN-12C fan modules are installed at the rear of the CE12804, CE12808, and CE12812 chassis to cool the chassis. Table 3-52 describes the functions of FAN-12C fan modules. When FAN-12C fan modules are powered on, they rotate at 40% of the full speed for at most 90s.
