Handling Process
Customer configure infocenter level on both act/stby SBC:
HRP_M[OSK_SBC_1]info-center source default channel 5 trap level informational
HRP_M[OSK_SBC_1]dis channel 5
channel number:5, channel name:snmpagent
MODU_ID  NAME     ENABLE LOG_LEVEL     ENABLE TRAP_LEVEL    ENABLE DEBUG_LEVEL
ffff0000 default  N      debugging     Y      informational N      debugging.
Root Cause
SBC system did not configure command of "info-center source default channel 5 trap level informational".
So system only will send warning level alarm and will not send info level alarm; power recovery belong to info level alarm. that is the reason of power alarm not recoveryed.
Suggestions
After configure the infocenter level it is necessary to reproduce the power alarm again in order to SBC send the info level alarm again for power recovery.
