I definitely tried several ports, all of which work for other
devices...no luck. It's an unmanaged switch. As noted in another
reply, a Trendnet TEG-S80g.

I've had it long enough that I'm inclined to just replace it.

Any recommendations are welcome. I was looking at a Netgear GS316
which seem to get pretty good reviews.
