I just had more equipment installed today and went up to a SWiM16, and the tech told me it needed a dedicated power line due to the 29V PI. No big deal, one was already run to where we put the PI, but I noticed on the switch the first SWiM channel says SWM1/PWR. I was mainly curious as to why this is? Would this be for a second power inserter? What is the purpose of that? Just a minor curiosity! Thanks to anyone who knows.
