| - | In Power over Ethernet systems, the power sourcing equipment (PSE) senses the Ethernet connection to detect if the powered device (PD) is plugged into the cable termination by applying a small voltage (2.7 V to 10 V) on the Ethernet cable and measures the equivalent resistance in at least two consecutive steps. During this phase, the PD must present a resistance between 23.75 kW and 26.25 kΩ. | + | In Power over Ethernet systems, the power sourcing equipment (PSE) senses the Ethernet connection to detect if the powered device (PD) is plugged into the cable termination by applying a small voltage (2.7 V to 10 V) on the Ethernet cable and measures the equivalent resistance in at least two consecutive steps.
