    维护 MX2020 电源模块

    Purpose

    为实现最佳路由器性能,请确认 PSM 的情况。

    Action

    定期:

    • 检查 PSM 的状态,方法是发出 show chassis environment psm 命令。

      此输出显示机箱 AC PSM 的状态:

    • 确保安排好电源和接地电缆,使它们不会妨碍检修其他路由器组件。
    • 例行检查 AC 或 DC PSM 面板和控制面板上的状态 LED,确定这些 PSM 是否工作正常。
    • 检查控制面板上的红色和黄色告警 LED。 PSM 故障或卸下 PSM 会触发告警,造成一个或两个 LED 亮起。 通过发出以下命令显示相关联的错误消息:
      user@host> show chassis alarms
    • 定期检查安装现场,确保连接到路由器的接地和电源电缆安全固定好,而且路由器附近没有湿气积聚。
