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-480SA-B FAQ
Q1: Which specific Huawei switch models are compatible? Can it directly replace the old fan?
A1: Compatible with Huawei S7700 (S7703/S7706, etc.), S9700 (S9703/S9706, etc.), and S12700 (S12704/S12708, etc.) series; the interface and installation dimensions are consistent, and it can directly replace the old fan module without additional configuration.
Q2: Does the fan module support automatic speed adjustment? What is the noise level?
A2: Supports intelligent temperature-controlled speed adjustment; the higher the temperature, the faster the fan speed, balancing heat dissipation efficiency and energy saving; operating noise ≤65dB, which is within the acceptable low noise range for data centers.
Q3: How many of these fan modules are needed per switch?
A3: The number of switches required depends on the switch model. S7703/S9703 requires 2, S7706/S9706 requires 3, and S12708/S12710 requires 4. It is recommended to equip or replace the switches according to the original factory configuration.
