Thread-topic: 802.3da MPOE Voltage Change Proposal

Following comments by Arkadiy in the last two drafts, I have reconsidered his proposal to increase the maximum MPSE voltage. Please see the attached presentation. I would like the Task Force to consider making the changes outlined in the slide deck during our meeting tomorrow morning.
