Classification Minimum Level
Daniel Feldman, PowerDsine
XXXX, XXX
Motivation and Direction
• Enhancing to Clause 33 classification, it was
agreed that
– The number of classes should rise
– The minimum class level should be lower than 3.84W
• Most applications need a maximum of 2W or
above
– The exceptions are sensor that could require less
than 1W
• For lower power requirements then 2W, other
power allocation methods can be used. Details
of such methods are implementation specifics
and beyond the scope of 802.3at
Motion
Move that:
The IEEE 802.3at Task Force determines
2W as the lowest PD class level.
