If your system came with a SCSI drive, this cable is already
connected inside your computer. If your computer did not
come with a SCSI drive installed, this cable came in the box
with your computer.
Follow the steps below to connect the SCSI ribbon cable to your
system board and drives. If at least one SCSI drive is installed,
begin with step 3.
1. Connect P1 of the SCSI ribbon cable to the SCSI A socket on
the main system board.
2. To route the cable to the first drive, guide the cable into the
gap between the lower SCSI drive bays and the bottom of
the computer, as shown below.
