We've got a lot of the RB750UP's in use, too. We power them right off the DC plant (27V) into the barrel connector (as opposed to PoE in). If I need more ports at a site, I'll use one as the router (powering backhauls) and one just as a switch (for APs). We're powering UBNT and Mikrotik gear. They've been solid so far.

I thought you were talking about the PowerBox (which is an RB750UP in an outdoor case). I'm not sure... I would assume it would be the same as if you plug the PoE out side of a power injector into something that doesn't support PoE... in my experience, they either work fine or something starts smoking :P Yeah, ether1-poe-in-long-cable would be it, and yes, it only applies on ether1.

It does have a big fat power supply, though. What happens if you try forced on to something such as a dumb switch or laptop? Are you talking about ether1-poe-in-long-cable ? That would only apply on ether1, wouldn't it?

I've seen some weird stuff happen trying to use poe-out auto, so I always set it to forced on. They're pretty much the same guts as an RB750UP in an outdoor case... they've been as reliable as any other MikroTik, in my experience.

I found that the default config (poe-out auto) works out of the box for Ubnt and a dumb switch. Just checking to see if anyone's found them to fail or anything obscure out in the field.
