Phone is dead! M7310

There is no power cord required for an M7310 set. The set gets all the power from the Nortel telephone system. Try plugging in your phone where another phone is active to ensure that your phone that you want to install is working. The phone flashes, then stops, then flashes, then stops... you just have to be patient when testing. Possible Troubles: -> It maybe the line cord, the cord that plugs in from the wall to the phone that can be damaged. -> the jack might be dead (wiring in the jack is pulled off) or inactive (there is no jumper from the office to the telephone system). -> the phone port from the telephone system might be dead.

Yes this phone requires a power cord
