Configuring Temperature Thresholds for Fan Speed Adjustment

Configuring Temperature Thresholds for Fan Speed Adjustment


The device uses fixed temperature thresholds to increase and decrease the fan speed by default. The fan speed increases when the device temperature exceeds the upper threshold and decreases when the device temperature falls below the lower threshold. If you want to keep the device working at a lower temperature, you can set lower fixed temperature thresholds.


  1. (Optional) Run display fan speed-adjust threshold minus

    The default temperature thresholds and the adjusted thresholds are displayed

  2. Run system-view

    The system view is displayed.

  3. Run set fan speed-adjust threshold minus threshold-value [ slot slot-id ]

    The temperature thresholds for fan speed adjustment are specified.

    The new thresholds are the default temperature thresholds minus threshold-value. After this command is executed, both the threshold for increasing the fan speed and the threshold for lowering the fan speed are reduced.


    The following switches do not support this command:
