Maybe I missed it because I only took time to skim, but I didn't see
where it said anything about not *generating* RFI. I saw one comment
that said something about ethernet not being particularly prone to
*receiving* RFI. My experience has been that PoE systems have all
the usual ethernet egress of RF across the HF-VHF spectrum *plus*
many of them have even worse issues caused by the switching power
supply.
I have a PoE system that powers an access point located atop one of
my towers. Its original power supply completely trashed 160 meters.
I cured that by going to a DC injector and using a linear bench
supply to provide power. Clearing up all the ethernet carriers while
there is ~200 feet of CAT6 running up into the midst of my antenna
farm is not so easy.

I've run into PeE systems that were VERY VERY VERY noisy on HF. I didn't
bother to stick around to fix them, but I suspect they might have been a
candidate for the bucket treatment.
