Thanks for the nice work, Mike/Steve.

If I remember correctly, you have six V2 T_boards. About the direction of the 
cable for these T_boards,  please make two more that is the same as the one 
you did, and the other three with a right angle turn but from the other 
direction than the one you did. 

We will also need a few (six) V2.1 T_boards assembled once SDU get the new 
boards. How many spare cables will you have after the above V2 T_board 
assembly? If the number is less than 6, we need to save them for V2.1 
T_boards. 

Best,
Zhenyu
