Oh, I see. Chuck made things easy by marking + and - on the input block
so you know what's what on the jumper diagram on the back of the card. I
know he's explained this before. Apparently I'm just a little slow this
week.

Yep. That's why I'm going to have a RSD to separate all "-48" loads at
the sites.
I think I'm working on too many things at once and confusing myself
and forgetting things, because I've done this before. :(

The Trango bonds their return to chassis, regardless of what the POE
does. So you need to check what else is on that power feed, and if
any of those devices also bond to chassis. If one or more is bonding
+ to chassis (that's Trango), then any other that bonds - to chassis
is gonna blow a fuse or let the smoke out.

Chuck, can you verify for me again.. the earth side of this thing
isn't tied to the negative side of the input block? I'd say no,
because obviously the green LED is on when wired as you have them
marked. And the red LCD when it's backwards. So the LEDs are just a
polarity indicator and has no bearing on what's what.
Just trying to wrap my mind around any potential issues when using
these for powering the old Trango radios (-48 on all four pairs,
return on shield) which I'm about to do. I'm out of Trango's -48 POE
boxes and ain't buyin no more.
I suppose sometimes I over-think things.
