Re: [802.3af] 802.3af standards
The P802.3af standards proposal is still in Working Group Ballot.
The current proposal supplies a nominal 48 Volts and up to 350 ma to the
Powered Device (PD)
The PD is expected to have an isolating DC-DC converter to generate
appropriate voltage and current for its internal use.

The current state of the comments and responses is posted on our web site
We represent several
Manufacturers including Mitel, Avaya and Cisco and all 3 require
different operating voltages today. These manufacturers are telling me
that the standard is still in discussion and that it
could be some time before released.
This is true.
Any information would be
helpful and appreciated.
