Arduino Ethernet Shield - POE

I have an Arduino Ethernet Shield that I want to add POE to. I have the POE power supply and I see the holes in the PCB for their installation. What I'm looking for is a schematic of the Arduino Etherner Shield that shows the addition of the POE power supply. I'm assumming that there jumpers somewhere that allow the POE to power the shield and Uno. I don't want conflicting power supplies floating around during development. Any help and guidance would be appreciated. Thank you in advance.

I could be wrong, but is it just not a case of adding the PoE module?

I have an Arduino Ethernet shield without a PoE module, but I also have the new Arduino Ethernet board with PoE module installed and there appears to be no jumpers linked.

Most schematics are normally contained within the hardware pages, such as http://arduino.cc/en/Main/ArduinoBoardEthernet
