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。

SCTP偶联中断故障处理故障现象：诺西端局CSGS45的单块ESB板故障，造成SCTP偶联的主通路中断，由于现网局间SCTP偶联均配臵了双通路，单块ESB板故障并不会导致局间SCTP偶联中断。
而实际情况是，CSGS45至中兴局向部分SCTP偶联中断，而到华为局向和其他诺西局向的SCTP偶联均正常，也就是说SCTP的双通路并未起到保护作用，对此，我们进行了分析，并排除了故障。
原因分析：分析判断可能原因：1、备用通路不通2、诺西端局硬件或配臵问题3、中兴端局硬件或配臵问题原因排查：SCTP（STREAM CONTROL TRANSMISSION PROTOCOL 流控制传输协议）能在两个端点之间提供稳定、有序的数据传递服务，在SIGTRAN协议的应用中，SCTP 上层用户是SCN 信令的适配模块（如M2UA、M3UA），下层是IP网。
偶联实际上是在两个SCTP端点之间建立的连接关系，任何时刻两个SCTP端点之间能且仅能建立一个偶联。
通路则是一个端点将SCTP分组数据发送到对端端点特定传送地址的路由。
在现网中，如下图1所示，两个端局之间配臵了4个偶联，每个偶联具有主备两条通路，并采用了心跳机制，即当某条通路空闲时，本端端点会生成相应的心跳消息并通过该空闲通路发送到对端端点，而对端端点收到消息后将立即发回对应的心跳确认消息。
该机制被用来随时监视偶联通路的可用情况，当某一条通路故障时，数据传送将立即切换到另一条通路上，以此来保持SCTP偶联的可靠性和稳定性。
通路1图1 局间偶联示意图图2 诺西端局偶联配臵示意图如上图所示，诺西端局的偶联建立在GISU板上，每一块GISU板对应一个偶联。
每个偶联的两条通路分别通过两块ESB板连接直IP承载网，进而与对端局相连。
本次故障起因为ESB1板故障，但单块ESB板故障只会导致偶联2条通路中的1条通路中断，根据偶联的心跳机制，数据传输将立即切换到另一条通路上，整个偶联将不会受影响。
