PoE Problems

Post by Froibo » Fri Feb 24, 2012 4:27 am

So the Arduino functions of the board work fine and the Ethernet LEDs are also signalling that there is communication to my router. However I cannot get the PoE to work. I have tried with both the jumpers being unaligned and aligned to the PoE headers. When I tested it with my multimeter I only get a reading of .7 volts on the + and - PoE headers.

Edit: So I think I answered my own question by rereading the PoE guide, sorry I don't know anything about Ethernet. From what I understand, the device on the other side of the EtherTen (i.e. my router) does not necessarily send the required 7-12 volts across the cord and I need to mod the cord. Correct?

You can use a power injector like the http://www.freetronics.com/products/poe-injector-4ch for the 28v POE http://www.freetronics.com/products/poe ... ulator-28v .

Also, Panoptic makes PoE adapters that can scale down your voltage to whatever you may need.
