馈线或者rru有问题,也是驻波告警

一般一起出现

一般一对出现

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,e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

X2邻区告警,说明对应外部邻区不好,后台维护处理即可

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

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

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
