Sending Power over LAN Cables?

[Kelemvor]

I know that there are network switches and such that can send power over their lines automatically, but for home use, has anyone ever used an adaptor thing like these from Linksys?

They look neat and are about $32 at Newegg. Not sure if they would work with non Linksys equipment or not (I have a NetGear wireless router). Would let me not have to run an extension cord through my ceiling.

any device that is "power over ethernet" compliant should work just fine. (phones, wireless, etc)

 

[Kelemvor]

The point is that these things work with items that are NOT PoE compliant. That's why it splits the cable back apart into a separate power plug and network cable...

I made some a whille back for powering a switch in the basement where I couldn't get power to. I followed a NYCWireless Article on how to make POE injectors. If you're savvy, you can do it very easily, and they work like a champ, and I only have about $5 in parts into them. I'm using the switch with about 65 feet of cable and I have no problems whatsoever with the included power brick.

Hope you can make sense of it all.


But to answer your question, they should work with anything you want them to work with providing you don't max out the line with power and the plugs on the things are compatible (size + polarity) with your hardware.

Yeah, I built few of these too.

Did Not look as nice as the Linksys. However I knew the Voltage and polarity of the each piece of Hardware that I used it with.

I would suggest being very very careful when contemplating to use on Hardware that is No Listed on the Linksys page.

P.S These gizmos have one side (the one to left on the Linksys page) that takes the VCC from a Known Unit (See Linksys list) and connected to a pair of wires in the CAT5e.

On the other side the two Wires are split out (see the unit to the right) of the Cable and connected to a Regular Round DC Brick Plug.

This DC plug can be plugged into any AP's Power supply jack. I.e. the receiving unit does not have to be a POE unit since it receives the VCC from a regular DC plug.

You have to make sure that the polarity and the Voltage of the Access Point is the same as the delivery unit.

Of course the only products listed on the page are LinkSys products. heh. Guess I can compare the info on the adaptor for my netgear 814 router and see what it says in comparison to the info on the linksys adaptor things.

 

[spidey07]

heh, serves me right. I thought it was just a run of the mill power injector.

<---needs to pay more attention.
