最佳答案
是的,修改一下风向
display fan 看看风扇的风向是什么,用fan prefer-direction slot slot-number { power-to-port | port-to-power }把系统期望风向与风扇风向修改一致。

需保证风扇模块的风向与设备的期望风向一致(可以使用fan prefer-direction slot slot-number { power-to-port | port-to-power }调整),否则设备会产生告警并发出较大噪声。

手动调整下方向就行了
fan prefer-direction slot slot-number { power-to-port | port-to-power }
