Root Cause
From logs, 
a.From 2009-10-08 15:52:22,This equipment was working with the 83-GSCC as active SCC board and the version is 5.36.18.44P01.The configuration on 83-GSCC board was fine. The following log is the operation log from the 83 GSCC board:
b.From 2009-12-03 23:17:49,One GSCC board was inserted to 82 slot and working as slave GSCC board, which was with 5.36.18.50 software version. As the version is not consistent between the active GSCC board and slave GSCC board, the configuration on the 83-GSCC board can’t be synchronized with the 82-GSCC board. So there was no any configuration on the 82 slave GSCC board.
c.The software version in formations of GSCC boards are shown as below, 5.36.18.50 (82-GSCC) and 5.36.18.44P01(83-GSCC).
d.After equipment was powered off on 2010-11-20 11:4:23, the 82-GSCC was working as the active GSCC board with null configuration. So NE lost all the configurations and was running with install state. 
After downloaded the configuration at 2010-11-20 18:11:2,all the services was restored.
Suggestions
To recover the Traffic and to clear alarms the above handling procedure must be followed.
