recommended operating conditions for extended periods of time may affect device reliability.
to VPORTN
4. Test done according to the IEEE802.3af 2 Point Measurement. The minimum probe voltages measured at the PoE−PD are 1.4 V and 2.4 V,
5. Measured with an external Rdet of 25.5 kW between VPORTP and VPORTN
6. This typical current excludes the current in the Rclass and Rdet external resistors.
