Does it have any auto sensing abilities or does it send out a specific voltage to all ports? February 18, 2016 at 2:12 pm #9866 StephenKeymaster Hello – The WS-POE-12-48v120w is passive, so there is not auto negotiation. The output voltage on all ports is 48v (determined by the power supply voltage).
