Snom 00004570 power adapter/inverter Indoor 10 W Black

The power supply unit for Snom desk phones

By default, Snom desk phones are supplied with power via PoE, therefore, for ecological and economic reasons, no power supply unit is included in the scope of delivery. However, if you do not use PoE in your network environment, this power supply is available. You will also need this if you want to connect more than one extension module to a telephone, i.e. from the second extension module onwards.
