SIMATIC S7-400 / S7-400H / S7-400F /FH: Energy supply Malfunction Within rsck0 cause s7-414fh goes Towards Halt

Dear expert
The fh system with s7-414fh went to stop mode.
After Power supply fail in rack0 and getting off its cpu, the cpu in rack1 went to stop.so h system was in stop mode.
I checked relevant OBs,except OB72,OB80 andOB88 other OBs are downloaded.
 Unfortunately buffer is reset and no more information is available.
Additionally cpu contain fail safe program.
Your kindly response is appreciated.
