CR52FCBH Fan Module

CR52FCBH Fan Module

Multiple CR52FCBH fan modules reside side by side on the air exhaust vent. When a fan module fails to work, the system can still work at the ambient temperature of 40°C for a short time of period. The CR52FCBH fan modules are hot-swappable.


The heat dissipation system allows the device to operate at the ambient temperature for a short time as long as, at the time of failure, the system has not been operating continuously for more than 96 hours and the accumulated operation time of the system per year does not exceed 15 days.


Table 1-84 describes the mapping between the CR52FCBH fan module and NIP6800 chassis.

Table 1-85 describes the indicators on the CR52FCBH fan module.

Table 1-85  Description of the CR52FCBH fan module indicators






If the indicator blinks once every 2 seconds (0.5 Hz), the fan module is working normally.


If the indicator blinks once every 2 seconds (0.5 Hz), the fan module or PEM is faulty, or not all PEMs are powered on.
