14  Fan 2: 
15  State    : FanDirectionFault
16  Airflow Direction: Power-to-port
17  Prefer Airflow Direction: Port-to-power

檢查交換機風扇配置信息發現交換機風扇的實際氣流方向為：Airflow Direction: Power-to-port（風道風向是電源側進風、端口側出風）；而配置用戶下看到風扇模塊的優選氣流方向為：Prefer Airflow Direction: Port-to-power（端口側進風、電源側出風），兩者不一致（交換機風扇反轉），導致交換機風扇狀態為：FanDirectionFault（風扇方向錯誤），風扇信號燈告警，交換機SYS信號燈告警。

處理方法：

fan prefer-direction命令用來配置用戶期望的風扇模塊的風道風向。undo fan prefer-direction命令用來恢復缺省情況。當風扇模塊的風道風向和設備當前期望的風道風向不一致的時候，系統會打印Trap和Log信息提醒用戶。缺省情況下，設備的期望風道風向為電源側進風、端口側出風（power-to-port）。

或者更改用戶期望的風道風向為power-to-port，保存配置，sys信號燈恢復綠色。
