目前诺西在上海移动现网中主要有2个系列的基站设备,分别为FLEXI EDGE 站型和MCPA站型,并以MCPA站型为主。
1.1 腔体更换步骤1)将故障所在的小区锁住2)将连接在腔体上的射频线做好标记3)先将腔体与载频的连接线拆除,然后依次拆除腔体上的连接线(只需拆除腔体一侧),卸除1/2跳线4)更换腔体,重新复原1/2跳线、射频线、连接腔体的数据线(切记所有连接线按原有顺序复原)5)解锁,重启BCF,观察所有载频是否正常工作、有无告警(注意有无话务,因动过1/2跳线需要观察RSSI值)6)与BSC确认此站是否处于正常状态(最好能等待1小时以上,观察故障是否会重复出现)2 载频更换步骤2.1 FLEXI EDGE站型载频更换步骤1)将故障载频锁住。
