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. To ensure that the device works 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:

    • S1720GF series
    • S1720GFR series: S1720-28GFR-4P
    • S2720EI series: S2720-12TP-EI, S2720-12TP-PWR-EI, S2720-28TP-EI, S2720-28TP-PWR-EI-L
    • S5720LI series: S5720-12TP-LI-AC, S5720-12TP-PWR-LI-AC, S5720-28P-LI-AC, S5720-28TP-LI-AC, S5720-28TP-PWR-LI-AC, S5720-28X-LI-AC, S5720-28X-LI-DC, and S5720-16X-PWH-LI-AC
    • S5720S-LI series: S5720S-12TP-LI-AC, S5720S-12TP-PWR-LI-AC, S5720S-28P-LI-AC, S5720SV2-28P-LI-AC, S5720S-28TP-PWR-LI-AC, and S5720S-28X-LI-AC
    • S5720S-SI series: S5720S-28P-SI-AC, S5720S-28X-SI-AC, and S5720S-28X-SI-DC
    • S5720I-SI series: S5720I-6X-PWH-SI-AC, S5720I-10X-PWH-SI-AC, S5720I-12X-SI-AC, and S5720I-12X-PWH-SI-DC

    If one of the preceding switches can set up a stack with other switch models that support this command, this switch also supports this command so that this command can be executed and delivered in the stack.
