We had a power hick up at my house and the bbu unit has 5 steady green lights then at bottom of the unit we are getting a yellow blinking light and a green light blinking?
Just wondering do we have system fault?
What model bbu do you have?
Which one of these is yours ?
I believe it the power reserve device we actually have of these 2 black boxes hooked up. One is for my phone and the other for my parents phone.
This is my ONT
