设备正常,但出现CF2A73
CF 2A73 是指无线单元联失丢失
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。
此故障也就是指DUG与RUS或RRUS通信丢失出现的故障!这样的故障多出现于拉远站(如6601这样光纤拉远设备)!如是DUG运行正常,可以先判断为RRUS电源掉电,拉远光纤给破坏,DUG与RRUS之间两头用的光模块是否击坏!建议先确定RRUS供电、光纤都正常,再进行更换光模块!一步步排除,很容易处理的!
1、2A73:无线单无元联系丢失。从做IDB看,还有就是从启DUG;
2、2A:73只有CF告警,The DUG has no contact or degraded communication移动通信,通信工程师的家园,通信人才,求职招聘,网络优化,通信工程,出差住宿,通信企业黑名单 u+J8e+I0a
with one or more RUSs/RRUSs marked as expected in the IDB.
具体操作如下:bbs.mscbsc.com2~8L;m,x:@!k
• Check that all RUSs/RRUSs circuit breakers or
fuses on the PDU are on or intact.
• Check that all RUSs/RRUSs is powered-on.
• Check that all defined RUSs/RRUSs in the
IDB correspond to the RUS/RRUS in the RBS.
Otherwise modify the IDB.
• Check that the Radio Interface cable between the
DUG and all RUS/RRUS are correctly connected
and in good condition.bbs.mscbsc.com3}9f"u)s5b(|0o0x
• Reset the RUS/RRUS not communicating correctly
with the DUG.
• Reset the DUG.MSCBSC 移动通信论坛2|2A1l3l3s9H:b8?
• Replace the Radio Interface cable between DUG

• Replace the RUS/RRUS not communicating
correctly with the DUG.
• Replace the DUG.
3、正常看看近端设备和远端是否有电 然后再去看光纤和 光模块
