>> WIKI: POE-Power Over Ethernet >> >> There's a seriously detailed wiki page up on Power Over Ethernet. >> >> [http://nycwireless.net/tiki-index.php?page=Poe ] >> Thanks Terry!
Terry's page is indeed helpful, I think I have one of those deployed still. I also saw another page on POE, and I use this technique now... (Sorry, I can't find the page with google at the moment).... I used to find it by googling POE and SOE. What I like about the technique here is, I don't need to test the CAT5 at all, it remains CAT5 certified. Take a wall-wart power supply. Cut the low voltage wire in half. Use a CAT5 Coupler. The white plastic one that are not for bulkhead use. Break in half on the seam. Cut the 4 wires for the POE pins - closer to one side, so they will be stubs on one side and plenty long on the other. (usually, Red/Green pair and White/Brown pair) LABEL this side POE and short-wire side Ethernet before closinng. Solder appropriate wire on. Make a hole (I use tiny diagonal cutters to make two V's for each wire pair) Close connector. One POE injector/rejector/dejector should connect to the power supply and one to the plug that you cut off. Use a short 1-3' CAT5 cable to connect to device. My own twist : to power two lightweight devices from one POE, don't cut the wire, just remove the insulation, (I use, um, a soldering iron to do that :-), solder, and now BOTH sides are POE, and the middle is a TAP or two-way INJECTOR. With a POE tap and an regular injector, you can figure out how to run a soekris board together with a Client Bridge, both powered from one POE feed. NOTE, check voltages/amperages - your actions are your actions, I used 48V power supplies so the amperage is very low. -- NYCwireless - http://www.nycwireless.net/ Un/Subscribe: http://lists.nycwireless.net/mailman/listinfo/nycwireless/ Archives: http://lists.nycwireless.net/pipermail/nycwireless/
