Figure 1. DC power connection, 50 pin SCSI I/O connector
"NC" model drives receive power from the host com- puter through the 80 pin combined SCSI I/O and power connector. No separate DC power connector is pro- vided on the drive.
SCSI address selection
On "N" and "ND" model drives, make sure that the SCSI bus address jumper(s) are properly set for the bus address assigned to the drive. See figures 3a and 3b showing the bus address select header and the jumper configurations that select addresses 0 through 7. Typically the primary boot device is set to ID 0, and the subsequent SCSI drives are jumpered in ascending
