The drive is always jumpered for 0,1,2,3. 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. --FritzM.
