Yair-

Because impedance is what is supplied by the PD
It is not a current source

Goeff ,

The spec. specify current range for each class. Why you prefer impedance?

Chad-

Please change one sentence to be more precise:

From

Hardware Physical Layer (HPL) classification occurs before power-on when the PSE asserts a voltage onto the PI and the PD responds with a current representing a limited number of power classifications.

To

Hardware Physical Layer (HPL) classification occurs before power-on when the PSE asserts a specificed signal onto the PI and the PD responds with an impedance representing one of a limited number of power classifications.

Thanks
