After electricity blackout this afternoon around an hour, all fios (landline phone and internet, i don't have tv) is not working. Watched videos checking ONT but I could not find how to open this motorola model. (Picture is from another forum but it is the same model to mine). The system status green light on BBU is repeating on and off cycle every 2 or 3 minute. Unplugged then plugged ont and bbu but it did not work. Any suggestions ?
