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
