How? It's specifically mentioned as a supported model. No solder required.

and as I said, I have these in production. I didn't do the power supply swap 
myself, but the brochure in the product page shows how you would install it.

The 2004 doesn't fit the Mikrotik 48vdc power supply. They're two totally 
different form factors. Sure you could crack the case open and make it work 
with some solder, but I figured we wanted parts that would fit.

I guess it depends on which 2004. The product page says it does work with one 
of them. We are using that one successfully on -48.

That 48vdc power supply doesn't work on at least the 2004...I don't know about 
the other CCR. It does on the 1009 (which was my first suggestion, but keep in 
mind that's an older TILE router)

Yeah, I just found that on their website. I didn't know they sold this.

The PW48V-12V85W power board can take -48vdc. Many of the CCR series can accept 
that PSU.

Are there are any Mikrotik models that definitely work with positive ground? I 
know I can use an isolated converter, but it would make me happier if I don't 
need one.
