[802.3_DIALOG] Call for interest - Single-Pair Ethernet Powering Cabling Restrictions

Dear Colleagues,

The following request for agenda time for a call for interest has been received from Chad Jones. It will be discussed at the IEEE 802 LMSC July 2024 Plenary meeting in Montreal, QC, Canada. If you have any questions, please contact either Chad Jones <cmjones@xxxxxxxxx> or me directly.
 
----

This is a call for interest (CFI) to initiate a Study Group to develop a Project Authorization Request (PAR) and Criteria for Standards Development (CSD) for a project to provide clarification on the cabling requirements for single-pair Ethernet powering.

The IEEE 802.3 Working Group's Power Delivery Coordinating Committee (PDCC) is working with other SDOs to avoid potential issues but has serious concerns about a currently proposed approach that an international cabling SDO has taken. In particular, the SDO is proposing to specify cabling at different current carrying capacities that do not support all the power classes that are presently defined in IEEE 802.3. This threatens the historic assumption that PoE is plug-and-play. It may be necessary to have additional information in IEEE Std 802.3 to provide guidance regarding the usage of such cabling.

----

The call for interest will take place during the IEEE 802.3 Opening Plenary on the morning of Monday 15th July. A call for interest consensus-building presentation has been scheduled to occur during the IEEE 802.3 PDCC Ad Hoc meeting from 19:00 to 21:00 on the evening of Tuesday 16th July. The vote to determine if a Study Group will be formed will take place at the IEEE 802.3 Closing Plenary on the afternoon of Thursday 18th July.

Best regards,
David Law, Chair, IEEE 802.3 Ethernet Working Group
