[8023-POEP] Agenda

["Clay Stanford (LTC)" <claystanfordltc@xxxxxxxxx>]

AGENDA/TOPICS
(See attachment for color formated agenda)


1.	Christian Beia presentation.
2.	Discussion on variable classification resolution
selectable by PSE vendor and selectable by PD vendor.
3.	Efficient Power Utilization (Robbins presentation)
4.	How many classes?
5.	Can we allow 4P AT PSE to operate each 2P set
autonomously from one in other.

-PSE limits the power per any 2P to XX watts.
-PSE performs detection and classification for any 2P.
	-If the PD is 2P then all is OK.
	-IF the PD is 4P then each 2P will receive XX watts
max.
	-PD is responsible for current sharing in order to
utilize the max power and not cause an overload
condition on any 2P.
-PSE would be required to turn on power on all 4P
within TBD time (1ms max?) only after detection and
classification ended successfully. Clay thinks an
issue here.
-If an outlet is split to two separate PDs then they
will be powered after PSE gets valid detection and
classification data on each pair.  This allows
flexibility in application and infrastructure
utilization as long as there is no hazard to equipment
or users and there are no potential interoperability
issues. 

•	Writing standard is easier
•	4P PD is more expensive because balancing is
mandated to be handled by PD
•	Some issues with backward compatibility with AF PDs
(Stanford presentation)
•	In a split cable installation using a 4P AT PSE, is
it expected that both PDs should receive power?


6.	Is Classification mandatory in AT?
7.	Merits to adding more info into class like vender
ID (Palmer)
8.	Robbins idea to limit heat during classification by
using class 1-3 and only use class 4 selectively
