LSPM1FANSB 以太网交换机风扇模块(电源侧出风)
发布时间:2021/9/9 9:58:00问题描述:
现场所有的S5560系列交换机风扇信号灯黄灯闪烁,前面板SYS信号灯红色常亮。
现场环境:
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。
