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 connectors on narrow SCSI cables are keyed for proper positioning—a raised
area on the outside of the header connector fits into a notch on the device con-
nector. The connectors on wide SCSI cables are shaped so that they can be
attached one way only.
If you are installing an external SCSI device
, connect one end of the external SCSI
cable to the SCSI bus connector on the back of the device.

If you are installing an internal SCSI device
, connect the colored edge on the
internal SCSI cable to the pin-1 end of the 50-pin connector (for a narrow
SCSI device) or the 68-pin connector (for a wide SCSI device) on the adapter
card, and then press the cable connector firmly onto the adapter card
connector.

If you are installing an external SCSI device
, connect the other end of the
external SCSI cable to the external connector on the adapter card.
For additional instructions, see the documentation that came with the adapter
card.

If you are installing an internal SCSI device
, connect a DC power cable to the
power input connector on the SCSI device.

If you are installing an external SCSI device
, connect the socket end of the
power cable into the AC power receptacle on the back of the SCSI device.
Connect the other end of the power cable into a standard electrical wall outlet.
Check all other cable connections. Fold all internal cables out of the way to pro-
vide airflow for the fan or cooling vents.
