Re:What is POE?
POE – Stands for Power Over Ethernet.
Normally you have to use two cables to connect to an Access Point (AP).
The Cat5 and the 12VDC for operation. If you put the AP in a remote place, it is clumsy to snake two cables.
Some manufactures connected in the AP the DC input to the unused pins of the CAT5. These APS called POE ready.
The injector is a small plastic box that has two inputs. One for the CAT5 and one for the DC.
The out put merges into One CAT5 that carries the DC in the spare leads to the AP. Thus only one CAT5 has to be snaked to the AP.
If you don't check carefully, and wrong pins are used the DC can end up in the Circuits of the NIC or the AP and fry them. To be safe use the injector made by the manufacture of the POE AP.
As usual with Add-ons, simple plastic box with three Jack and simple internal wiring goes for about $30. (As compare to a Router on sale for the same price).

Re:PoE (Power over Ethernet) is a way to use 2 of the unused wires in an ethernet cable to supply power to a networking device. Basically it eliminates the need to run a power wire to the device, which can be useful if you want to install something like a router or WAP in a place where there is no handy electrical outlet.

Re:Every now and then, a topic comes along where I don't even understand the question. What the heck is a POE injector, and why would you care about it? (Just curious, I obviously have nothing useful to contribute to the thread!)

Re:Yeah, I looked at the do it myself solution, but this is a business deployment so I want to do it right. Thanks for the tips, I definitely agree about using a PoE injector and AP from the same manufacturer. D-Link seems to have a PoE injector, my guess is that it will work with the new D-Link Ap 900+ (or whatever it is).
Re:Just build your own poe injector, its not too rough.
Buy one or use it for inspiration (http://www.demarctech.com/products/POE/poe-main.html)
Re:Yeah the AP has to be factory wired.
Basically the DC Jack inside the AP has to be connected to two unused pins in the RJ-45 Jack.
I would suggest using POE AP only with the brand counter part, otherwise you take the risk of frying your NIC, or AP.
There is a cheap way to do home made POE without touching the AP, but I need time, and the capacity to post pictures in order to explain how to do so.
