交换机告警灯亮

设备正常运行，但是一致有日志告警：ALARM:Power 2 Get Fan airflow direction Failed on slot 1 ,please check it.
类似情况：The airflow direction of The two Power Fan is Different on slot 1 ,please check it

查看到有相关的风扇的告警，先调整下风扇风向保持和期望风向一致，修改后问题依旧

查看设备的信息第二个电源模块无显示，但是设备的电源是Normal

后续查看资料有关于电源模块的手册说明

Before you install a power module, make sure its airflow direction is as required.在安装电源模块以前，请确认电源模块气流方向和安装环境的通风要求一致。

Do not install power modules that provide different directions of airflow on the same device. 不同风向的电源模块不要混插在同一台设备上

建议使用一样型号的电源模块

更换同型号电源模块，若相同型号的模块还是告警，建议替换模块测试下
