If you’re looking for a switch which is POWERED by POE and also supplies POE to the devices which are plugged into it then all such switches I’ve seen (including the 2 above I believe) only offer two (2) ports which supply POE.
(I used plain old 802.3af in the tests illustrated in those photos.) The box accepts both and the packaging and specs prefer AT, but I’ve never used them on anything other than AF.

I spent a while stress testing and to learn its limits. If you don’t already have one and are into little handy tools for the collection, pick up a PoE multimeter. Little tiny box with a screen that displays power, amps, voltage, etc. Great for troubleshooting longer distances or sketchy wiring etc. And while on the subject, you can also get that in USB form which is even more useful for IoT stuff, since the market is full of really bad quality copper!
