工程:新疆農七師錦龍電力調度自動化升級項目
現場人員:張健
問題描述:
現場所有的S5560系列交換機風扇信號燈黃燈閃爍,前面板SYS信號燈紅色常亮。
現場環境:
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爲:Airflow Direction: Port-to-power;而配置用戶下看到風扇模塊的優選氣流方向爲:Prefer Airflow Direction: Power-to-port,兩者不一致(交換機風扇反轉),導致交換機風扇狀態爲:FanDirectionFault,風扇信號燈告警,交換機SYS信號燈告警。
處理方法:
因爲風扇模塊的實際氣流方向是無法改變的,只能去改變風扇模塊的優選氣流方向和風扇實際氣流方向一致,操作步驟如下:
[QIANZHI-B]
[QIANZHI-B]dis fan
Slot 1:
Fan 1:
State : FanDirectionFault //工作狀態報錯
Airflow Direction: Port-to-power //實際氣流方向
Prefer Airflow Direction: Power-to-port //優選氣流方向
Fan 2:
State : FanDirectionFault
Airflow Direction: Port-to-power
Prefer Airflow Direction: Power-to-port
調整交換機的優選氣流方向:
[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 //工作狀態正常
Airflow Direction: Port-to-power //實際氣流方向
Prefer Airflow Direction: Port-to-power //優選氣流方向
Fan 2:
State : Normal
Airflow Direction: Port-to-power
Prefer Airflow Direction: Port-to-power
修改配置後,交換機各指示燈恢復正常。
