某局点 S7606 板卡故障

%Feb  5 13:47:46:777 2026 IPTV-HeXin-S7606-1 DEVM/2/BOARD_STATE_FAULT: Board state changes to FAULT on Chassis 0 Slot 0, type is LSQ1SRPA.

%Feb  5 13:47:46:777 2026 IPTV-HeXin-S7606-1 HA/5/HA_SLAVE_REMOVED: Slave board in slot 0 is removed.

%Feb  5 13:51:54:939 2026 IPTV-HeXin-S7606-1 DEVM/5/BOARD_STATE_NORMAL: Board state changes to NORMAL on Chassis 0 Slot 0, type is LSQ1SRPA.

现场S7606-S设备VRRP组网，承载三层组播业务，2月5日下午13:47出现VRRP主设备slot 0备用主控板异常fault，并在4min后自行恢复。同时，现场反馈自当天14:00至15:17出现组播业务卡顿的情况。

1.     首先分析了slot 0板卡异常重启的原因，通过对诊断中记录的信息逐一分析，确认板卡重启原因为冷重启，此类情况通常为单板自身硬件问题所致：

  ===============display mainboard  switchinfo===============

22:Slave  Board 0 is removed  at 13:47:00 02/05

23:Slave  Board 0 is inserted at 13:50:00 02/05 Reason:Cold Restart

  ===============local logbuffer 0 display 0 from-highmemory===============     //高端内存没有信息

===============================================================================

  ===============_display  reboot  last-time===============

===============================================================

Slot 0 Last Running End Time :    0/0/ 0  0:0:0

2.     进一步排查本次板卡重启对业务的影响，经查看，确认现场业务正常时slot 0的内部互联HG口（主控板上和业务板内部互联的口）几乎没用实时流量，即业务流量实际并不经过slot 0板卡中转。备用主控板卡slot 0的重启实际不会影响到设备上的流量转发。

Slot No:0 --- Chip No:0

4.     综合以上，现场板卡异常重启问题系板卡单体硬件故障。组播卡顿问题从已有信息分析未发现有交换机侧的相关异常。

1.     板卡异常重启问题为硬件故障，更换slot 0备用主控板。
