OSN6800 Power_Fail alarm analysis and solution

Publication Date:  2012-07-24 Views:  70 Downloads:  0
Issue Description
During OSN6800 pilot project commissioning, check the equipment alarm and find the SCC board has alarm "POWER_FAIL".
Alarm Information
POWER_FAIL:
Power failure
+5V Power 2 failure
Alarm Parameters(hex):0x05 0xff 0xff 0xff 0xff
Handling Process
1.Pull out the SCC board, find the jumper which controls the battery used or not state is incorrect. 
2.Change the jumper state to be using battery.
3.Pull in the SCC board and check, the alarm disappeared.
4.Reset the date and time information, Power off the equipment and then power on, the information saved.
      
Root Cause
OSN6800 is new equipment and not only one equipment has this alarm. We doubt it is the power module problem.
After power off, I find the equipment time and date information lost and become to the initial data:1990-01-01 00:00:00. So I suppose it is the SCC board's battery problem.
Suggestions
The jumper will be set before delivery.
