It is a bit confusing. I could label them 1&2. I think if you do + and -
then the green LED will come on if opposite the red.
If I can make it less confusing please let me know how. Obviously if you
put all pins to the -48 no leds will come on.

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.
