It was already on the .brd file downloaded from ARDUINO ETHERNET SHIELD 2.
EDIT: After a little google search: POE.
Ummm I will give it a try with another part as long as I get the eagle files (.brd or .lbr).
Of course I don’t expect it to be perfect but save me tons of time to make parts like these, so I will do the correct fixes in order to import it into Fritzing.
