LTEeNODEB2009-12-222日常故障处理2009-12-223ENODEB系统2009-12-2241.NoContact无连接告警此系列告警是由电调故障引起,具体情况如下:告警描述:ContactlostwithresourceobjectTimeout:FailedtogetanuConnectIndicationContactlostwithresourceobject。ThealarmiscurrentlytogglingTimeout:FailedtogetanuConnectIndication。Thealarmiscurrentlytoggling告警显示状态如下图所示:电调状态为:2009-12-225故障原因:电调码已经识别,但是电调没有起来处理办法:1、重新打入Bin文件,然后重启RRU,观察状态2、若方法1不行,需要将该电调拆下,重新安装3、若以上两条均不好用,则更换新电调注:特例为基站有Thealarmiscurrentlytoggling告警(告警当前正在切换),但是电调无故障,需重启基站消除此告警。2009-12-2262.NTPSystemTimeSyncFault(NTP系统时钟同步错误)告警原因:一般是由NTP的IP错误引起get.NTP可以查看状态处理方法:将图中IP修改为正确的地址即可2009-12-2273.NumberOfHwEntitiesMismatch(实际硬件数量不匹配)告警描述:SCUthatisnotconfigureddetected故障原因:基站侧更换过DU板卡,导致DU板卡识别不了机框信息。处理方法:利用moshell登入基站,重新配置。(需要问现场督导具体)getcabi查看机框配置信息,然后使用set指令修改,输入修改指令时,等号前后不加空格,如图所示:机框信息2009-12-2282009-12-2294.PasswordFileFault(密码文件故障)故障原因:基站密码设置错误处理方法:重新设置密码,passwd;rbs;rbs5.Plug-InUnitGeneralProblem插入单元故障故障原因:可能是RRU或者DU故障处理方法:现场检查故障原因6.Plug-InUnitHWFailure(插入单元硬件故障)故障描述:SinglecoreMPHWfailure故障原因:DU硬件故障,可能出现的状态为基站无限重启处理方法:更换DU7.PowerFailure(供电故障)故障描述:PowerFailureAlarm(PFA),id2,port1/2/3,cascadeNo1故障原因:RRU侧没有通电处理方法:让施工队给RRU加电2009-12-22108.SystemClockQualityDegradation系统时钟质量降级告警CSystemClockQualityDegradationSynchronization=1(replaceable_unit_problem)故障描述getsynchSynchronizationId1adminQualityi[8]=1616161616161616(NOT_DEFINEDNOT_DEFINEDNOT_DEFINEDNOT_DEFINEDNOT_DEFINEDNOT_DEFINEDNOT_DEFINEDNOT_DEFINED)degradationIsFault0(DEGR_NOT_FAULT)featureStatePtpFreq0(DEACTIVATED)featureStatePtpTime0(DEACTIVATED)featureStateSyncEth1(ACTIVATED)fixedPositiontruelicenseStatePtpFreq0(DISABLED)licenseStatePtpTime0(DISABLED)licenseStateSyncEth0(DISABLED)minQualityLevel1(QL_SSU_A)nodeSystemClock4(FREE_RUNNING_MODE)operQuality21(NOT_DEFINED)selectionProcessMode0(QL_DISABLED)sfnInitializationTime1980-01-06T00:00:19syncRefActivityi[8]=11111111(INACTIVEINACTIVEINACTIVEINACTIVEINACTIVEINACTIVEINACTIVEINACTIVE)syncRefPriorityi[8]=10000000syncRefStatusi[8]=00000000(FAILEDFAILEDFAILEDFAILEDFAILEDFAILEDFAILEDFAILED)syncReference[8]=告警诱发原因TDD站点只能是GPS出现故障导致该告警出现FDD站点则是因为Syncheth同步出现问题,导致该告警出现解决方法①设备软件版本进行升级,但目前已经是最高版本故此方法只使用于低版本。②添加GPS③若GPS出现故障,则需要上站检查GPS硬件以及网线。2009-12-2211getsynch=========================================================================================================115SystemFunctions=1,Licensing=1,OptionalFeatures=1,TimeAndPhaseSynchWithGPS=1==================================================================================================================================================================================================================158TransportNetwork=1,Synchronization=1=========================================================================================================SynchronizationId1adminQualityi[8]=1616161616161616(NOT_DEFINEDNOT_DEFINEDNOT_DEFINEDNOT_DEFINEDNOT_DEFINEDNOT_DEFINEDNOT_DEFINEDNOT_DEFINED)degradationIsFault0(DEGR_NOT_FAULT)featureStatePtpFreq0(DEACTIVATED)featureStatePtpTime0(DEACTIVATED)featureStateSyncEth1(ACTIVATED)fixedPositiontruelicenseStatePtpFreq1(ENABLED)licenseStatePtpTime1(ENABLED)licenseStateSyncEth1(ENABLED)minQualityLevel1(QL_SSU_A)nodeSystemClock2(LOCKED_MODE)operQuality21(NOT_DEFINED)selectionProcessMode0(QL_DISABLED)sfnInitializationTime1980-01-06T00:00:19syncRefActivityi[8]=21111111(ACTIVEINACTIVEINACTIVEINACTIVEINACTIVEINACTIVEINACTIVEINACTIVE)syncRefPriorityi[8]=12000000syncRefStatusi[8]=33000000(OKOKFAILEDFAILEDFAILEDFAILEDFAILEDFAILED)syncReference[8]=syncReference=Equipment=1,Subrack=1,Slot=1,PlugInUnit=1,TimingUnit=1,GpsSyncRef=gpssyncReference=Equipment=1,Subrack=1,Slot=1,PlugInUnit=1,ExchangeTerminalIp=1,GigaBitEthernet=12009-12-22129.TemperatureExceptionalTakenOutOfService特殊温度导致服务停止告警mTemperatureExceptionalTakenOutOfServiceAuxPlugInUnit=RRU-1,DeviceGroup=ru(RUunitnon-functional)故障描述RRU没有信号,起不来。strru===================================================================================ProxyAdmStateOp.StateMO===================================================================================3631(UNLOCKED)0(DISABLED)Equipment=1,AuxPlugInUnit=RRU-13801(UNLOCKED)0(DISABLED)Equipment=1,AuxPlugInUnit=RRU-23971(UNLOCKED)0(DISABLED)Equipment=1,AuxPlugInUnit=RRU-3)故障诱发原因RRU馈线未接,馈线故障,天馈系统故障。合路器故障以及设备高温等问题导致RRU内部高功率无法发射出去。解决方法•lhrufmgetfaults/////先查看RRU硬件是否有问题return_loss_too_low_port_a•cabx查看RRU温度是否正常•以上都没问题则排查馈线及合路器部位,先检查合路器是否符合LTE频段,再用好的小区的馈线与有问题小区做调换,•然后解闭小区,并重启RRU,如果问题跟馈线走,就说明是馈线原因,换馈线即可解决。(大部分都是馈线及合路器问题)strru===================================================================================ProxyAdmStateOp.StateMO===================================================================================3511(UNLOCKED)1(ENABLED)Equipment=1,AuxPlugInUnit=RRU-13681(UNLOCKED)1(ENABLED)Equipment=1,AuxPlugInUnit=RRU-23851(UNLOCKED)1(ENABLED)Equipment=1,AuxPlugInUnit=RRU-32009-12-221310.TemperatureAbnormalPerformanceDegraded温度异常导致性能降级告警mTemperatureAbnormalPerformanceDegradedAuxPlugInUnit=RRU-1,DeviceGroup=ru(Normaltemperaturetoohigh[DL/A])故障描述RRU部分服务停滞告警诱发原因高温导致RRU部分服务停滞告警解决方法cabx查看RRU温度查看是否有
