hanspeterkaufmann3 years ago000Hello, do I have to buy a power supply unit separately for this phone? And which one would it be? Thank you HampiShow in original language (German)info3 years ago • purchased this product000purchased this productYou can also supply the telephone with power via PoE. Functionally and cost-wise, it makes no difference.The power supply unit has 5V and can be found at Galaxus.A PoE feed is also OK.The crucial thing is where do I have a 230V socket?Show in original language (German)Comment1 comment
