[802-LMSC] IEEE P802.3dw draft PAR and CSD response - Fault Managed Power (FMP) Ethernet Interoperability
Dear IEEE 802 LMSC members,
In support of subclause 9.2 'IEEE 802 LMSC Approval' of the IEEE 802 LMSC Operations Manual, please find below the required information with respect to the IEEE P802.3dw IEEE Standard for Ethernet Amendment: Ethernet and Fault Managed Power (FMP) PAR for consideration at the July 2026 plenary.
Best regards,
David
[1] Draft PAR and CSD responses:
Draft PAR: <https://mentor.ieee.org/802-lmsc/dcn/26/lmsc-26-0141-00-LMSC-ieee-p802-3dw-draft-par.pdf>
Draft CSD responses: <https://mentor.ieee.org/802-lmsc/dcn/26/lmsc-26-0142-00-LMSC-ieee-p802-3dw-draft-csd.pdf>
[2] Explanatory technical background material:
The success of Power over Ethernet (PoE) has created demand for power over Ethernet cabling that exceeds the maximum PoE power of 71.3 W. Updates to safety standards have enabled a new method, FMP, that can deliver up to several kilowatts over appropriate Ethernet Cabling while constraining the energy delivered into a fault. The specification of FMP operation on Ethernet cabling is needed to provide an interoperable method to meet the increased power demands. It is also necessary to specify concurrent operation between FMP and Ethernet to mitigate potential interference from FMP, which could cause data loss. This interference could occur within the cabling for twisted-pair Ethernet as well as within the port for both twisted-pair and fibre-optic Ethernet.
[3] Status of the development of the PAR:
The draft PAR and CSD responses are pending approval by the IEEE 802.3 Working Group at the July 2026 plenary.
