LTE告警解释说明V1.1

RRU端口信号低故障，引起故障的原因为：1，安装工艺；2，跳线问题；3，驻波比故障
RRU服务请求告警 设置系统参数时候不成功导致RRU挂死，重启基站可恢复 对应的八通道站点的RRU下面第9个接口就是Port I口没有关闭导致的，需要站点登陆闭锁掉此端口，因为基站不需 要监测此端口的驻波比告警 对应的二通道站点的RRU下面第3个接口就是Port R口没有关闭导致的，需要站点登陆闭锁掉此端口，因为基站不需 要监测此端口的驻波比告警 license里面缺少combe(小区合并)的feature，需要申请含有小区合并feature的license 此处报S1链路失败，查看MME也是disable，但是能ping通MME和下一条地址，那么查看以下几个参数是否正确： 1. plmn ; 2. tac ; 3. enbid 小区下面的noOfRxAntennas和noOfTxAntennas两个参数的值不一样，设置成同时为1（室分单流），或者同时为 2（室分双流）；宏站一般不会出现此故障 驻波比超高告警

告警解释说明及处理
NTP服务器地址不通告警 两种情况：1.时间设置不对，2.License内没有开通feature RRU硬件告警 RRU不活导致的RRU服务不活 RRU服务请求告警，说明RRU不活 光路不通告警，对应小区光纤不好，或者RRU断电导致无光发出 驻波比告警，可以cabx查看RRU驻波比，一般驻波比设置为1.5db，小于1.5db就不会有告警 驻波比超标导致RRU服务告警 光路高误码率告警，检查光模块是否有异常，更换光模块检查 服务超时导致小区不活

RRU硬件告警（cabx可查看到RRU亮红灯） 小区无服务，此处可看到RRU吊死了 RRU断电告警，需要工程队或者代维上站检查RRU电源情况 RRU光纤告警 站点已经打了的License中缺少对应的feature功能，请查看License文件中是否有对应的feature MME传输SCTP协议对应地址不通，lst sctp查看到对应的s1地址是否通畅，主要问题是传输PTN故障，联系传输 PTN处理 EnodeB密码没有设置，从而出现告警，需要用命令passwd ; rbs ; rbs设置密码 没有打license，所以导致这样的告警

时钟同步告警，一般GPS挂掉才会出现(get . nodesystem ; nodeSystemClock 2 正常值为2，其他不正常 ) GPS信号不稳定，没有锁定，从而导致GPS不活 GPS没接好，无信号，从而导致GPS不活 时钟同步告警，GPS没有连接故障 MU电源连接有问题或者MU框坏 风扇告警，如果重启无效，需要更换整个MU 硬件告警，需要更换MU 温度警示告警，需要更换MU DUL板软件故障
