Cisco Power Injector - AIR-PWRINJ4

Unanswered Question
Jan 8th, 2013

                   Hi there, I have a quick question about Cisco Power Injector.

                    we bought a number of Air-PWRINJ4 year ago,  mainly for extending the power via Cat5 ethernet cable to AP 1225 in warehouse. the output is 56V 0.55A. 

                    Now I have a couple of spare left, my quesiton is if it is OK to directly power 3502I AP, which requires imput 48V and .35A. from the bag of Air-PWRINJ4, it indecates that the 3500 series is also included.

I have this problem too.

I wouldn't, since the 1252 injectors supply more voltage than required.

HI Scott, thanks for the reply,  I have tested it works fine, but what will happen if we plan to use it for long run, does it will demage the APs?    in the packaging bag it says: Power Injector - AP 1140/1250/1260/3500 Series - SPARE

on the site I am setting up the AP, there is no POE switch and I don't have adapter with exact output for APs.

Roy,

If it didn't blow up when you connected it, then it will be fine. I'm guessing there is something that must be regulating the power output. Again, you should be fine.

You have no choice.  You either use the PWR-INJ4 (20.0w) or wait for the release of the PWR-INJ5 (15.4w).

Another option is here.
