[Clas12_rich] RICH electronics

Hi All,

the optical fiber distribution box will require 4U 
It would be great to have it just above or below the VXS crate. 
This 4U rack space is adequate to distribute the fibers of two rich sectors (i.e. no additional rack space will be required for the fibers of the second sector)

Thanks,

Matteo
