虾？有甘既事？？

CF 2A:73 这个告警我遇到过，基本判断就是 载频与DU链接的 尾纤问题。因为我上次遇到的时候我更换了光模块还是出现，再次让厂家更换跳纤后就再没出现过。

不是爱立信设备问题，估计是尾纤两端 脏了 清洁一下。可以在MU侧测试一下 损耗 如果过大，就清洁一下，或者换一条试试。

如果RUS没有问题看看风扇吧

学习下。我们这边也上这种设备了

这个就是不好准确查找是哪点出了问题，只好换光纤、换光模块一样一样地试，还有就是改馈线的延迟值

开站的时候没开延时，具体步骤现在记不住，有需要可以问网友怎么开，这种拉远站最好是要开延时的。

请教高手，延迟值怎么改啊？有什么作用？谢谢。本人是6000新手

configuration-define-delay 可以先设置为1042ns

CF 2A:73 无线单元联系丢失，（此告警为硬件故障）。 检查IDB配置是否正确；检查RRUS/RUS安装是否完成，并且设备已加上电；检查光缆、法兰盘、尾纤、光电转换模块等是否OK；确定RRUS/RUS与DUG的RI口正确连接，并且连接OK；断电重启RRUS/RUS；如果以上都正常，重启DUG；还不能解决替换问题单元RRUS/RUS；替换DUG。
建议查看下DUG、RRU、光纤、光模块。
