Can I power up 750UP into poe port from Tp-link 48v injector like TL-PoE200 (or TL-PoE150S) ?
does somewho know ? it has AUTO Negotiation, but I dont know how it works.
Thanks for help. Sorry for bad English.
RB 750UP is not capable of working from 48V, you have to have some converter to lower it to 24V range.
something along these lines:
