So my setup is as follows:
USW Flex (https://dl.ubnt.com/datasheets/unifi/USW-Flex_DS.pdf)
2 AP AC Lite (https://dl.ubnt.com/datasheets/unifi/UniFi_AC_APs_DS.pdf)
1 AP AC LR (https://dl.ubnt.com/datasheets/unifi/UniFi_AC_APs_DS.pdf)
First try was to power the USW from the US8 and then hook the three AP ACs to it.
That did not go well, random disconnects, APs loosing power. That told me, too little power.
So I bought airFiber POE injector 50V 60W to power the USW Flex with, did make the change to it took power from the POE injector.
That did not go well either, however I hooked them up, when nr 3 is plugged in, it does not get any power.
I have read the data sheets and done the math not matter how I count the power should be enough in case 1.
Anyone has any input what is not happening here? Have I miscalculated biggly?
