找了一段时间，发现网上貌似没有这个问题。希望版主能够有多点的人关注下，谢谢

故障描述为 RU/RRU硬件故障处

Follow the instructions below until the fault is resolved.
• Follow the instructions in the related faults.
• Check the feeder cables, especially that they are
connected to the correct ports on the ALNA/TMA.
• Check that ALNA/TMAs are working correctly, for
example, by monitoring the ALNA/TMA current
power consumption with the OMT and comparing it
with expected consumption.
• Switch off the power to the pinpointed RUSs/RRUSs.
Wait at least 10 seconds and switch on the power.
• Replace the RUSs/RRUSs.
• Note: It may take up to ten minutes before the
alarm is ceased.

虽然翻译了一下有点。。。。。还是要非常感谢的！！

这个没有具体的说明文档，难搞点了。。。。

RUS故障坏的一般不多见，清洁光纤更换光模块或者DUG到RRUS之间的光缆即可。

呃，我描述的不好吧。。。。。苦逼的文笔，兄弟见谅！！！

把尾纤和光模块直接换了，不清洁了！！！这个屌故障烦人的啊。。。。

应该先看下相关告警，这步很重要，然后在判断

爱立信的故障描述一般很准，分析一下相应的替换单元！
我也很久没接触爱产信的东西了，怀念！

朋友很少开这种站吧。这个故障不是硬件问题，是你数据做的有问题不懂可以加我QQ85880828.

之前也有同事碰到这个问题，后来貌似自己恢复了，也不知道是怎么回事

这个问题我这边也已经恢复了。好像是网优把RRU的功率改了导致的。具体原因还不知道！！！倒霉催的。。。。。。。

3.2.79.4 Description
RBS6000
There are internal hardware faults in one or more RUS/RRUS/AIR/mRRUS, the RUS power supply or in some device, that is, a feeder or TMA consuming too much power.
The severities of the faults are indicated by the related faults.

RBS6000
Follow the instructions below until the fault is resolved.
 Follow the instructions in the related faults.
 Check the feeder cables, especially that they are connected to the correct ports on the ALNA/TMA.
 Check that ALNA/TMAs are working correctly, for example, by monitoring the ALNA/TMA current power consumption with the OMT and comparing it with expected consumption.
 Switch off the power to the pinpointed RUSs/RRUSs/AIRs/mRRUSs. Wait at least 10 seconds and switch on the power.
 Replace the RUSs/RRUSs/AIRs/mRRUSs.
Note: It can take up to ten minutes for the alarm to cease.

6601设备 调试对于基站调试督导来说 ，最基本确保的就是BSC机房数据与设备的IDB的一致性。设备线缆连接正确，6601的DUG与RRU之间由于是用光纤连接 需要测试纤芯衰耗是否在正常范围内，可以在MU侧用光功率计测试MU发光经过RRU之后返回到MU的衰耗。正常是1---12DB之内。大于12DB就会出现（ 重启了一下设备，故障消失，5~6小时或者更长一段时间后故障出现，设备倒闭）注意：光纤是否中间存在调纤 之间是否有法兰转接 。

目前我只能提供这些方法。不足之处请各位指出,谢谢！！！
