Colleagues- This ballot for a TSB for power delivery over UTP calls out a higher requirement than we do for our project. Further, their more stringent requirement (5e) vs. our requirement (5) has nothing to do with power delivery. The differences between 5 & 5e have nothing to do with the DC performance of either cabling system.I have highlighted the area of concern on page 4 of the draft within comment CS04
I urge that P802.3at send a liaison letter to TIA asking that the proposed TSB change the requirement (Category 5e) to that which we call out in our draft (Category 5) on the technical basis that PoE+ can be supported onlegacy systems of Cat 5 cabling.
Best regards, Geoff Thompson
