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.

Designers can set the current by changing the value of the external resistor according to the following table:

Table 7: Value of the external classification resistor for the different PD classes of power

Class	PD max. average power (W)	RCLS (Ω)
0	13	2k
1	3.84	150
2	6.49	80.6
3	13	51.1
4	25.5	35.6
