How to solve the conflict – PD side
Proposed Solution
Effects on PD specifications
–PD operating voltage range: No effect. Remains
–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.
