> I even managed to find an unmanaged 16-port 2.5GbE PoE ... It's a no-name Chinese brand, but who cares?

Does it have a NRTL certification (UL or the like)? This is something I'd look for in a PoE switch, which often have internal power supplies specced for several hundred watts. Potential fire hazard. If it were a non-PoE switch plugged into a standard 12V/2A external power supply or the like, then I'd be with you, who cares if it's a no-name Chinese brand.

(btw, MokerLink, a previously-unknown-to-me Chinese brand, gave me excellent support last night. I complained a switch wasn't working. They asked for a video, then told me they're sending me a replacement. It's being delivered tomorrow. So at least some of these no-name Chinese brands are earning some trust.)

That is a very good point. Mine is from an actual brand and obviously OEMed by someone who makes a lot of these (there are many, many brands selling something with "S25-1602P" in the part number and slightly different stickers, and even more closely related designs), so I feel fairly confident, but yes.
