Oh, ok, somehow I missed that!

Thanks for giving the link, I’ll have to see if Streakwave or someone has them, 
this would be a lot easier.

I could just take that to a barrel connector on the back and make sure that the 
proper feed polarity is used.

You can buy -48VDC power supplies directly from MT for the 2004.  It's simple 
to install them.

I’m not familiar with -48v power plant.

What would it take to “convert” from a -48v wire pair to a 12v 1A wire pair?

I’m converting a Mikrotik CCR 2004 to -48v plant in my cabinets.
The 2004 doesn’t have replaceable power supplies so I was just going to cut and 
wire the 12v headers on the motherboard to a DC barrel installed on the back of 
the unit alongside the AC Input…
Not sure if that would be best, easiest? It’s easy to find 48v to 12v 
downconverters, but -48v is a mystery to me.

Help me demystify it?
