The fan module dissipates heat for the chassis so that the chassis can work properly and efficiently within the operating temperature range.
Noise reduction
When the fan module is powered on, it rotates at 48% of the full speed for at most 5 minutes. After the fan module communicates with the MPU normally, the MPU controls running of the fan module.
Automatic fan speed adjustment
After the fan module communicates with the MPU normally, the MPU controls the speed of the fan module according to temperature of cards in the chassis.
Alarm report
The fan module can report alarms on fan module failures and communication failures.
Electronic label
The MPU reads and loads the electronic label of the fan module through RS485.
Hot swapping
Supported

FAN-480SB-B FAQ
Q1: Which Huawei switch models does the FAN-480SB-B support? How compatible is it?
A1: It mainly supports Huawei CE8800 series mid-to-high-end switches, CE7800 series high-end switches, and some models of the CE9800 series. The size and interfaces are fully matched, with 100% compatibility; it can be used simply by plugging and unplugging.
Q2: What are the advantages of directional cooling? Can it meet the full-load cooling requirements of the switch?
A2: Directional airflow can concentrate cooling on core heat-generating components, resulting in more precise and efficient heat dissipation; it fully meets the full-load cooling requirements of mid-to-high-end switches, and the core temperature can be controlled within a safe range.
Q3: How is redundant deployment achieved? Will a single module failure affect equipment operation?
A3: It supports parallel redundant deployment of 2-3 modules. The switch system monitors the status of each module in real time; after a single module fails, the remaining modules automatically speed up to compensate, the cooling capacity is not affected, and the equipment continues to operate normally.
