[Matt Slaga (US)]

Are these 7941s or 7941G-GE?  The power requirements are different.

I've done this.  I have some of the injectors (PN:  AIR-PWRINJ2) powering some 7940 phones without issue.  I've had these in a small office for a couple years.  They are 48V output at .35A.

I've used both the POE injector and the power cube plug on 7940 phones.
