I have just purchased a tp-link TL-WA901ND (http://wiki.openwrt.org/toh/tp-link/tl-wa901nd) and was pretty miffed to discover that PoE was not 802.3af compliant, as the reason for buying it was to use with my poe switch.
using the provided PoE injector it powers up.
I took the injector apart and it looks like pin 4 + 5 are +ve (the pin in the middle of the power connector) and 7 + 8 are -ve. power plug is 12v 1A
Is it possible for me to hack my access point to work in active
Note that Active PoE means using the same line as data, so you really want to do it? The difference between active PoE and passive PoE will be the availability of negotiate power requirements among equipments. If you want to go ahead (because I think your switch doesn´t power up your router), you have to add some resistance between pins to fool the switch at power up and then remove it.
