If you are installing an internal SCSI device
, firmly press the SCSI cable’s header
connector onto the 50- or 68-pin connector on the back of the device. The con-
nectors on narrow SCSI cables are keyed for proper positioning—a rais ed area on
the outside of the header connector fits into a notch on the de vice c onnector. The
connectors on wide SCSI cables are shaped so that they can be attached one
way only.
