Functions

FAN-16A fan modules are installed at the rear of the CE12816 chassis to cool the chassis. Table 2 describes the functions of FAN-16A fan modules.

Table 2 Functions of FAN-16A fan modules
Function Description
Noise reduction When the fan modules are powered on, they rotate at 40% of the full speed for at most 90s. After the fan modules communicate normally with the MPU, the MPU controls running of the fan modules.
Automatic fan speed adjustment After the modules communicate normally with the MPU, the MPU controls the speed of fans according to temperature of cards in the chassis.
Alarm reporting The fan modules can report alarms on loss of communication, fan failures, abnormal fan speeds, and blocking of a single fan.
Electronic label The MPU reads and loads electronic labels of the fan modules through I2C buses.
