MPC MX960故障排除
问题
描述
MPC 未正常工作。
解决 方案
只要 MPC 位于运行路由器中,就监控位于操作接口上的 MPC 上方标记为 OK 的绿色 LED。
路由引擎在两个条件下将 MPC 软件下载到其中:路由引擎 启动 Junos OS 时 MPC 存在,以及安装了 MPC 并通过前面板上的 CLI 或按钮联机请求 MPC。然后 MPC 运行诊断,在此期间 OK LED 闪烁。当 MPC 联机并正常工作时, OK LED 稳定亮起为绿色。
确保 MPC 正确固定到中平面。检查每个弹出器手柄是否顺时针方向旋转并紧密不拉。
检查 MPC 上的 OK/FAIL LED 以及工艺接口上的 OK 和 FAIL 线卡 LED。当 MPC 联机并正常工作时, OK LED 稳定亮起为绿色。
show chassis fpc
发出 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 Temp CPU Utilization (%) Memory Utilization (%) Slot State (C) Total Interrupt DRAM (MB) Heap Buffer 0 Online 36 3 0 2048 14 13 1 Online 40 5 0 2048 26 13 2 Online 41 6 0 1024 7 43 3 Online 43 5 0 1024 16 57 4 Online 24 3 0 1024 13 21 5 Empty 6 Online 43 5 0 1024 16 57 7 Empty 8 Empty 9 Empty 10 Online 24 3 0 1024 13 21 11 Empty
注意:命令
show chassis fpc
