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 kΩ 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 |
