[802SEC] IEEE P802.3cq Maintenance #13: Power over Ethernet over 2 pairs and IEEE P802.3cr Maintenance #14: Isolation

Dear Colleagues,

In support of subclause 9.2 'IEEE 802 LMSC Approval' of the LMSC Operations Manual, based on its '48 hour' rule provision, and the concurrence of the sponsor chair as required, please find below the required information in respect to two IEEE 802.3 maintenance PARs.

Best regards,
  David


IEEE P802.3cq
=============

Title: Standard for Ethernet Amendment: Maintenance #13: Power over Ethernet over 2 pairs

[1] Draft PAR and CSD responses:

Draft PAR: <https://mentor.ieee.org/802-ec/dcn/18/ec-18-0140-01-00EC-ieee-p802-3cq-standard-for-ethernet-amendment-maintenance-13-power-over-ethernet-over-2-pairs.pdf>
CSD responses: Not required.

[2] Explanatory technical background material:

Editorial and technical issues have been identified in Clause 33, Power over Ethernet over 2 pairs. These issues need to be addressed to improve the accuracy and clarity of the standard.

[3] Status of the development of the PAR:

The draft PAR is pending IEEE 802.3 Working Group approval at its closing plenary Thursday.


IEEE P802.3cr
=============

Title: Standard for Ethernet Amendment: Maintenance #14: Isolation

[1] Draft PAR and CSD responses:

Draft PAR: <https://mentor.ieee.org/802-ec/dcn/18/ec-18-0140-01-00EC-ieee-p802-3cq-standard-for-ethernet-amendment-maintenance-13-power-over-ethernet-over-2-pairs.pdf>
CSD responses: Not required.

[2] Explanatory technical background material:

There are subclauses titled "Electrical isolation" throughout IEEE Std 802.3 requiring isolation meet one of three electrical strength tests with references to the IEC 60950 "Information technology equipment - Safety" series. IEC 60950, however, has been replaced by the IEC 62368 "Audio/video, information and communication technology equipment" series and therefore an update to all isolation material in IEEE Std 802.3 is required.

[3] Status of the development of the PAR:

The draft PAR is pending IEEE 802.3 Working Group approval at its closing plenary Thursday.
