  6. Verify that the new fan module is working properly.

    Normally, after the new fan module is inserted into the chassis, the fans inside it immediately starts drawing air from the chassis. In this case, you can check whether the new fan module is working properly in the following ways:
    • Check the FAN indicator on the panel of the fan module. If it is green, the fan module is working normally. If the indicator is red, the fan module is not working normally.
    • Run the display fan command on the console interface to view the running status of the fan module. The fan module is working normally if the following is displayed:
    <sysname> display fan 
    Slotid    : 18
    Present   : YES
    Registered: YES
    Status    : AUTO
    FanSpeed  : [No.]Speed
    Slotid    : 19
    Present   : YES
    Registered: YES
    Status    : AUTO
    FanSpeed  : [No.]Speed

    The preceding command output indicates that the new fan module is normal. If the new fan module fails to work normally, contact Huawei technical personnel.
