倒换GCLK出现KSW告警属正常.doc

SR2131470报告 问题描述 BSC11在9月14日下午13:28左右重启,14:20左右恢复.9月15日凌晨 ，对BSC11进行GCLK倒换的过程中,发现KSW报出4&6告警.怀疑提供时钟的MSI存在问题，将其更换后送至Motorola硬件研发部门进行分析。 问题分析/调查过程1) 9月15日凌晨现场处理的过程 倒换GCLK之前没有KSW的4&6告警 15/09/06 00:10:33 MMI-RAM 0115 - disp_act 0ACTIVE ALARM INFORMATION FOR LOCATION 0:Device Alarm Clear (Subtype) Code Type Tag(hex) Date/Time Description- - - - - -MMS 55 0 0 16 FMIC 00000001 09-14-2006 Synchronization Loss OOS 14:37:13 Timer Expired Estimated restoral-60.0 secsMMS 54 1 0 16 FMIC 00000001 09-14-2006 Synchronization Loss OOS 14:37:08 Timer Expired Estimated restoral-60.0 secsMMS 54 0 0 16 FMIC 00000001 09-14-2006 Synchronization Loss OOS 14:37:08 Timer Expired Estimated restoral-60.0 secsMMS 3 0 0 16 FMIC 00000001 09-14-2006 Synchronization Loss OOS 14:37:14 Timer Expired Estimated restoral-60.0 secs 倒换主备GCLK成功 15/09/06 00:18:36 MMI-RAM 0115 - swap 0 gclkGCLK swap may cause alarms on other devices.The swap may take approx. 10 seconds.Are you sure (y=yes,n=no)? yCOMMAND ACCEPTED15/09/06 00:19:45 MMI-RAM 0115 - !state 0 gclk * *DEVICE STATUS INFORMATION FOR LOCATION 0:OPER STATES: D:Disabled E:Enabled B:BusyADMIN STATES: L:Locked U:Unlocked E:Equipped S:Shutdown Last Transition RelatedDevice State Reason dd/mm hh:mm:ss Function- - - - -GCLK 0 0 0 B-U GCLK Phase Locked 15/09 00:18:51 NoneGCLK 1 0 0 E-U GCLK Phase Locked 15/09 00:18:51 None 倒换后报出KSW 4&6告警15/09/06 00:20:18 MMI-RAM 0115 - !ddisp_act 0ACTIVE ALARM INFORMATION FOR LOCATION 0:Device Alarm Clear (Subtype) Code Type Tag(hex) Date/Time Description- - - - - -MMS 55 0 0 16 FMIC 00000001 09-14-2006 Synchronization Loss OOS 14:37:13 Timer Expired Estimated restoral-60.0 secsMMS 54 1 0 16 FMIC 00000001 09-14-2006 Synchronization Loss OOS 14:37:08 Timer Expired Estimated restoral-60.0 secsMMS 54 0 0 16 FMIC 00000001 09-14-2006 Synchronization Loss OOS 14:37:08 Timer Expired Estimated restoral-60.0 secsMMS 3 0 0 16 FMIC 00000001 09-14-2006 Synchronization Loss OOS 14:37:14 Timer Expired Estimated restoral-60.0 secsKSW 3 1 0 6 FMIC Untagged 09-15-2006 6.12 Second Reference Loss (KSW) 00:18:52KSW 3 0 0 6 FMIC Untagged 09-15-2006 6.12 Second Reference Loss (KSW) 00:18:52KSW 2 1 0 6 FMIC Untagged 09-15-2006 6.12 Second Reference Loss (KSW) 00:18:52KSW 2 0 0 6 FMIC Untagged 09-15-2006 6.12 Second Reference Loss (KSW) 00:18:52KSW 1 1 0 6 FMIC Untagged 09-15-2006 6.12 Second Reference Loss (KSW) 00:18:52KSW 1 0 0 6 FMIC Untagged 09-15-2006 6.12 Second Reference Loss (KSW) 00:18:52KSW 0 1 0 6 FMIC Untagged 09-15-2006 6.12 Second Reference Loss (KSW) 00:18:52KSW 0 0 0 4 FMIC Untagged 09-15-2006 Clock A Signal Loss (KSW) 00:18:52KSW 0 0 0 6 FMIC Untagged 09-15-2006 6.12 Second Reference Loss (KSW) 00:18:52 这些KSW的告警属于倒换GCLK过程中的正常现象,它们在GCLK倒换成功后由主用BSP自动清除2)将MSI插入Motorola实验室的BSC后,这些KSW依然会在倒换GCLK过程中出现,但在几分钟后自动清除 倒换主备GCLK成功 09/10/06 18:11:29 MMI-RAM 0115 - swap 0 gclkGCLK swap may cause alarms on other devices.The swap may take approx. 10 seconds.Are you sure (y=yes,n=no)? yCOMMAND ACCEPTED倒换后报出KSW 4告警 09/10/06 18:11:53 MMI-RAM 0115 -* (4) Clock A Signal Loss* - Severity: CRITICAL Category: EQUIPMENT* - KSW 0 1 0 (KSW)* - Site: 0 Cage: 0 Slot: 1* - Functional Unit: Site 0* - Time: Mon 9/10/2006 18:11:59:000* - Alarm Type: Fault Management Initiated Clear* - FRU Serial Number: X56FZW1X8S* - FRU KIT Number: SLN7131ECB* - Hardware Version Number(hex): 05* (4) Clock A Signal Loss* - Severity: CRITICAL Category: EQUIPMENT* - KSW 0 0 0 (KSW)* - Site: 0 Cage: 0 Slot: 27* - Functional Unit: Site 0* - Time: Mon 9/10/2006 18:11:59:000* - Alarm Type: Fault Management Initiated Clear* - FRU Serial Number: X56FZW0FSW* - FRU KIT Number: SLN7131ECB* - Hardware Version Number(hex): 05* (4) Clock A Signal Loss* - Severity: CRITICAL Category: EQUIPMENT* - KSW 1 0 0 (KSW)* - Site: 0 Cage: 1 Slot: 27* - Functional Unit: Site 0* - Time: Mon 9/10/2006 18:11:59:000* - Alarm Type: Fault Management Initiated Clear* - FRU Serial Number: X56X2D0465* - FRU KIT Number: SLN7131ECB* - Hardware Version Number(hex): 05 一分钟后告警自动清除 09/10/06 18:12:52 MMI-RAM 0115 -* (4) Clock A Signal Loss* - Severity: CLEAR Category: EQUIPMENT* - KSW 0 1 0 (KSW)* - Site: 0 Cage: 0 Slot: 1* - Functional Unit: Site 0* - Time: Mon 9/10/2006 18:13:51:860* - Alarm Type: Fault Management Initiated Clear* - FRU Serial Number: X56FZW1X8S* - FRU KIT Number: SLN7131ECB* - Hardware Version Number(hex): 05* (4) Clock A Signal Loss* - Severity: CLEAR Category: EQUIPMENT* - KSW 0 0 0 (KSW)* - Site: 0 Cage: 0 Slot: 27* - Functional Unit: Site 0* - Time: Mon 9/10/2006 18:13:51:860* - Alarm Type: Fault Management Initiated Clear* - FRU Serial Number: X56FZW0FSW* - FRU KIT Number: SLN7131ECB* - Hardware Version Number(hex): 05* (4) Clock A Signal Loss* - Severity: CLEAR Category: EQUIPMENT* - KSW 1 0 0 (KSW)* - Site: 0 Cage: 1 Slot: 27* - Functional Unit: Site 0* - Time: Mon 9/
