I'd like to put a Portal unit at a location in my apartment where I have ethernet but no power. I have attempted to give myself a crash course in Power over Ethernet (PoE), but could use advice from someone who knows what they're doing. The understanding that I've scraped together is that I need an injector that produces at least 36W (maybe this one) and a splitter that can produce 12V 3A (which I can't find, but here's one that produces 12V 4.5A). Then I plug the injector into the wall and my main Portal, connect the injector's output to the splitter, and hook the splitter's power and data outputs up to the second portal.
A couple questions:
- Do I have this right at all? Am I making a terrible mistake here?
- How do I make sure that the power cable that comes with the splitter is compatible with the Portal?
- Does PoE at this high wattage slow down the data?
- Do I need a splitter that produces exactly 3A? Will the fact that the injector produces only 40W help? Should I prefer an injector that produces only 35W to keep the amperage down?
