Hi Tony,

I’m speaking of the G740 at C13 on the RK11-C backplane, appearing on sheet 
RK11-C-06 in the engineering drawings and described in the last paragraph of 
section 3.2.5 in the RK11-C manual?  

On my RK11-C, this is jumpered to enable only drives 0 and 1; all other jumpers 
are unpopulated.
