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 | |||
