Are there any options for conference phones that will run on in-line power?

I have this problem too.

I think the new 7937G Conference stations will support PoE.

Thanks Manu!

Does anyone know if the 7936 or 7935 would run on in-line power?

Hi Ryan,

These units require 30 volts so I guess no standard PoE :) What I am guessing is that you would like to eliminate to "rats nest" of wiring that these rely on for power.

We have used the power module in the wiring closet and then standard Cat5E or Cat6 to the phone but only up to about 100 feet so far. This does make the setup much more aesthetically pleasing.

Here are the specs;

Cable Specifications

Keyed RJ-45 plug for the 25-ft. CAT 5 cable connection on the bottom of the IP Conference Station unit

Keyed RJ-45 plug for the 25-ft. CAT 5 cable connection on the PIM

RJ-45 plug for the 6-ft. CAT 5 cable connection on the PIM

30-volt power connector for power connection on the PIM

From this doc;

Hope this helps!

AS stated above 7937 supports inline power

7935&36 needs special adapter

All of this helps---Thanks guys!

Is there a diagram or something that would show the phones that work with in-line power?

I guess I am looking for the phones that would work almost plug-and-play versus the phones that would require a special adapter (ie 7935 and 7936).
