I created a PCB with the W5500 that supports POE. The W5500 works fine when it is powered externally, but it will not connect to the switch when it is powered using POE. I have verified that it is getting the proper 3.3 volts. Everything is based off of the reference schematic and the RJ45 jack I am using is the ARJP11B-MASA-B-A-EMU2. Are there any changes that should be made to the reference schematic when using POE?
Here is a link to the datasheet for the RJ45 jack. It has a built in transformer.
