敲敲放通,高端路由器 巡检中的AI动作检查和HG故障检查
问题描述
SR8806-X-S 巡检内容过程中遇到两个问题，slot0主控槽位的AI动作检查，slot0和slot4之间HG故障检查
过程分析
AI动作检查，时间距离较近，告警级别为严重。

解决方法
AI动作检查的告警就是由于这个hg down引起的，两个报警一起出现。
1.检查slot0和slot4单板是否有插紧，螺丝是否有拧紧。 //螺丝拧紧后故障消除
2螺丝拧紧后故障仍未恢复。则需要在slot0和slot4之间hg口有报障，交叉验证确认故障位置。//更换备件前，Slot 0和slot 4的连接器需要先检查下（包括单板和机框槽位），确保连接器没有弯针等异常，排除机框问题。
