    维护 MX960 FPC

    用途

    路由器可在机箱前部的 DPC 插槽中垂直安装一个灵活 PIC 集中器 (FPC)。 为使路由器达到最佳性能,请确认 FPC 的情况。

    操作

    定期:

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

    • 输入 CLI show chassis fpc pic-status 命令。 下例显示 DPC 插槽 12 中安装的 FPC:
      user@host> show chassis fpc pic-status
        Slot 0   Online       DPC 40x 1GE R
          PIC 0  Online       10x 1GE(LAN)
          PIC 1  Online       10x 1GE(LAN)
          PIC 2  Online       10x 1GE(LAN)
          PIC 3  Online       10x 1GE(LAN)
        Slot 1   Online       MX FPC Type 3
          PIC 0  Online       1x OC-192 SONET
          PIC 1  Online       1x OC-192 SONET
      

      注意: 在 MX 系列路由器中安装 FPC 时,FPC 占用最多两个 DPC 插槽。 槽位号与编号最小的 DPC 插槽对应。
