H3C出现：如下报错信息，

出现：

[H3C]fan prefer-direction slot 1 power%Jan 1 04:30:13:401 2013 H3C DEV/1/FAN_DIRECTION_NOT_PREFERRED: Fan 1 airflow direction is not preferred on slot 1, please check it.

解决办法：

检查交换机风扇配置信息发现交换机风扇的实际气流方向为：Airflow Direction: Port-to-power；而配置用户下看到风扇模块的优选气流方向为：Prefer Airflow Direction: Power-to-port，两者不一致（交换机风扇反转），导致交换机风扇状态为：FanDirectionFault，风扇信号灯告警，交换机SYS信号灯告警。
处理方法：
因为风扇模块的实际气流方向是无法改变的，只能去改变风扇模块的优选气流方向和风扇实际气流方向一致，操作步骤如下：

[QIANZHI-B]

[QIANZHI-B]dis fan

Slot 1:

Fan 1:

State : FanDirectionFault //工作状态报错

Airflow Direction: Port-to-power //实际气流方向

Prefer Airflow Direction: Power-to-port //优选气流方向

Fan 2:

State : FanDirectionFault

Airflow Direction: Port-to-power

Prefer Airflow Direction: Power-to-port

调整交换机的优选气流方向：

[QIANZHI-B]fan prefer-direction ?

slot Specify the slot number

[QIANZHI-B]fan prefer-direction slot 1 ?

port-to-power From port to power

power-to-port From power to port

[QIANZHI-B]fan prefer-direction slot 1 port-to-power

[QIANZHI-B]

[QIANZHI-B]dis fan

Slot 1:

Fan 1:

State : Normal //工作状态正常

Airflow Direction: Port-to-power //实际气流方向

Prefer Airflow Direction: Port-to-power //优选气流方向

Fan 2:

State : Normal

Airflow Direction: Port-to-power

Prefer Airflow Direction: Port-to-power

修改配置后，交换机各指示灯恢复正常。
