How to solve the conflict – PD side

„Proposed Solution

„Effects on PD specifications

PD operating voltage range: No effect. Remains 37-57V.

PD classification in 802.3at (including Class 4) should be mandatory and not optional

The enhanced classification table will be divided to two parts:

(See details in “An Extended Classification Proposal- Proposal #1, Vancouver BC, Nov. 2005)

„Part a: power classes that can work with either 44V or 51V.

„Part b: power classes that can work only with 51V minimum at the PSE.

This may be documented in the Informative section of the standard.
