    维护 MX480 MPC

    用途

    路由器可在机箱前部的插件架中水平安装最多六个 MPC。 为使路由器达到最佳性能,请确认 MPC 的情况。

    操作

    定期:

    • 检查控制面板上的每个 MPC 插槽正上方的 LED。 当 MPC 正常工作时,标记为 OK 的绿色 LED 稳定亮起。
    • 检查 MPC 上的 OK/FAIL LED。 如果 MPC 检测到故障,MPC 会向路由引擎发送告警消息。
    • 输入 CLI show chassis fpc 命令检查已安装 MPC 的状态。 如示例输出所示,标记为 State 的列中的值 Online 表示 MPC 正常工作:
      user@host> show chassis fpc
