    TX Matrix Plus 冷却系统故障排除

    问题

    以下报警、LED 和其他指示表示冷却系统存在问题:

    • 控制面板上一个风扇盘的 FAIL LED 亮起为红色。
    • 控制面板上一个风扇盘的 OK LED 未亮起。
    • 报警表示风扇发生故障或缺少风扇盘。
    • 一个或多个风扇盘以不断增加的速度运行。
    • 报警表示 TX Matrix Plus 路由器温度超过“温度稍高”或“温度高”阈值。
    • 由于 TX Matrix Plus 路由器的温度超过最大(“温度高”)阈值,电源自动关闭。

    解决方案

    要排除冷却系统的故障:

    1. 观察控制面板上的 LED。 以下 LED 表示存在问题:
      • 风扇盘的 Fail LED 亮起为红色。
      • 控制面板上的红色报警 LED 亮起。
    2. 观察控制面板显示屏,以确定故障源。 报警情况次数以及每次报警源都会显示在屏幕上。
    3. 将手放在机箱后部排气口的附近,确定风扇是否将空气排出机箱。
    4. 按以下方式使用 show chassis fan 命令确认每个风扇的状态是否为 OK 以及每个风扇是否都 Spinning at normal speedFan Tray 0Fan Tray 1 是指前部上下两个风扇盘中的风扇, Fan Tray 2Fan Tray 6 是指后部风扇盘中的风扇。

    7. 输入 show chassis alarms sfc 0 命令获取有关报警情况来源的信息:
      user@host> show chassis alarms sfc 0
      • 温度高:
        • 一个或两个电源上的 PEM OK LED 未亮起—确认电源风扇是否正常运行。
        • 一个或两个电源上的 FAULT LED 亮起—确认电源风扇是否正常运行。
        • 如果两个电源均发生故障,则系统温度可能超过阈值,从而导致系统关闭。 如果 TX Matrix Plus 路由器温度超过可接受的最大值,则 TXP-CB 会关闭电源。
      • 风扇故障—如果其他风扇正常工作,则可能是该风扇出现故障,需要更换风扇盘。

    有关报警的信息,请参阅表 1

    标记为 ”LCD Message” 的列中的文本出现在控制面板的显示屏中。 标记为 “CLI Message” 的列中的文本显示在以下命令的输出中: show chassis alarms 命令。
