I just need some consulting, which hardware to buy.
It is said RB260GS (not P) switch could receive power from passive PoE 1st copper port. Which injector should I use, will RBGPOE do the work? Which power supply should I plug into injector? There is 12V power supply included with the switch, is it enough (assuming the cable will have some losses, and switch is said to work from 6V)?
I suggest Mikrotik staff to document this topic more thoroughly. Also if I am correct, it is worth adding a link to this injector to the RB260GS page into "Related products" section.
