Sales rep unknowledgeable, need advice on setup

Hello everyone!

I bought an ultra gateway a few days ago. (and love it!) I wanted to replace my existing WiFi router with ubiquiti access points (each room of my house has ports as I ran them when remodeling)

The sales rep sold me on U6+ access points, however, he failed to mention the need for POE. I haven’t opened the two I bought yet…

What do you recommend as my next step to fix this issue? Should I just go back and buy a switch that powers POE? If so, I’m assuming I need one that has at least a 30W budget?
