Hello, friend!
1. Check whether an ONT alarm is generated when the power adapter is removed or the power button is pressed. If the ONT is powered off, an alarm is generated when the ONT is powered off.
2. ONTs of all types and versions can generate this alarm when the ONT is powered off.
[Error][Alarm-Log]AlarmID:104001,AlarmLevel:Error,Device reset. Cause: System reset after beingpowered on, Terminal:OTHER
