Hi Zhenyu and Flemming,

For the current setup, only one module on the top is conflict with the 
cooling tray. The other one on the back side is fine.
So we probably going to find some module which has a larger bending radius 
could fit in.
Bill showed us that we could measure the distance between cooling tube to the 
inner side of modules before the installation. This could help us to find the 
module with larger bending radius in the first place. There was a half inch 
difference between some of the modules (my memory could be wrong on the 
numbers but we did see a noticeable difference).

There are two potential conflict area on each disk which is the top two 
cooling trays and bottom two cooling trays.
The cable trays seem not conflict with the cooling tube from our previous 
dummy module test.

Best,

Xu
