Good morning. I'm hoping to get some help here on this forum. My wife runs some hotels here on the coast of North Carolina. Of course we recently had Hurricane Florence pound us. For a few days. And we lost power in the hotel for over a week. Any who. There is a Mitel sx-50 system here and none of the cards are lighting up. 5 line cards and 1 trunk card. The power button is lit up on the left, but that's it. I checked all the fuses using a voltage meter. I unplugged the system first of course. The fuses are good. Anyone have any ideas?
