Installed Fios TV One - 1 main unit and 2 minis. On the main unit and 1 of the minis, the left lights are white and the right lights are off. On the 2nd mini, the left light is white and the right light is green. Why are the lights on the 2 minis different, and what does the right green light on 1 of the minis, but not the other, indicate?
