Potential of frying DisplayLink USB 3.0 Docking Stations with Power over Ethernet?

POE should not fry the dock. The Ethernet actually goes to a Realtek PHY interface before being passed to the DisplayLink chip anyway, so any POE would be filtered out by the PHY anyway.

I think any problem you are seeing would not be caused by POE.

Thank you for the information!

So just curious, but what does the PHY interface do?
