Issue Description
Fan speed adjustment for S series fixed switch
Solution
"S series fixed switches (except S1700 switches) use any of the following heat dissipation modes: forced heat dissipation, intelligent heat dissipation, and natural heat dissipation. 
1. Natural heat dissipation applies when a switch does not have a built-in or external fan.
2. In intelligent mode, the fans start to operate only when the ambient temperature goes higher than a specified value.
3. In forced mode, fan modules keep working when the switch is running and automatically adjust the speed according to the switch temperature.

For fan-equipped switches that run V200R003C00 or a later version and use forced heat dissipation or intelligent heat dissipation, you can run the set fan speed-adjust threshold minus command to set the temperature threshold for fan speed adjustment. For switches using forced heat dissipation, the new threshold is the default temperature threshold minus threshold-value, and the temperature thresholds for increasing and decreasing fan speed are both reduced. For switches using intelligent heat dissipation, this command reduces the temperature thresholds for starting and stopping the fan."
