Editing Server/NIC

==Welcome==

Welcome to the OCP Mezzanine NIC subgroup under OCP Server Work Group. The goal of this subgroup is to form a healthy ecosystem in Mezzanine NIC space, under OCP framework.

===Guideline===
We are here to build a supportive, informative and inclusive community:


'''Supportive'''

	- Support implementation questions

	- Evaluate new use cases

'''Informative'''

	- Share the latest topics and trends related to OCP Mezz NIC spec

	- Share both challenges and opportunities

'''Inclusive'''

	- Take community feedback and make iterations to proposal before submitting major revision to work group and IC

	- Open to both adopters, and observers

==Get Involved==

4. Key mechanical updates: 

- Agreed on guiding feature and card sizes 

- Reduce to 2x sizes (Small and Large form factors; detail see latest spec draft)

To be closed:

- Front bracket / latching mechanism design for small and large form factors

- Right Angle connector vertical offset(3.05mm vs. 3.50mm); Need to decide and close based on Tolerance analysis

- Straddle Mount connector offset and PCB footprint; Need to decide and close based on 1U use case study


5. Coming working sessions and proposal of agenda:

-#7 12/6 : 2hr working session; ME and EE runs in parallel; close on ME opens and clarify the rest of draft work

-#8 12/13: 3-4hr: All draft work due for 1st pass of edit of all chapters. 1st cross review with changes suggested and agreed

-#9 12/20: 3-4hr: Review changes and post 1st draft
