Re: [AFMUG] DC-DC Converter
Oh...just because they've done it, doesn't mean it can't be done better.
My complaint with the indoor unit was that there was no way to mount it
to anything. They needed some eyes for screws, or keyholes on the back,
or something along those lines. The outdoor version wasn't particularly
rugged for an outdoor device, and still nothing to mount it to. You
either dangled it out of the bottom of the device, or zip tie it to the
mounting pipe.

They are converting from 48v 802.3af to 12V passive PoE on the spare
pairs. Are you looking at the same application, or something else?
