I was wondering before I fry one of my Cisco IP phones if I can use an AIR-PWRINJ3 instead of the IP Phone version to power it, I have a
7971G-GE and a few AIR-PWRINJ3 injectors from a friend who was getting rid of them at work. It currently runs on the power cube but would prefer to wall mount it and not have a wire running up the wall.And if I do use this injector will I loose gigabit and what is the main difference between the two versions that Cisco has.
