10-20 Dell Precision 610 Mini Tower Systems User’s Guide
If you are installing a SCSI host adapter card
, configure the card and install it
in an empty expansion slot (see “Installing an Expansion Card” in Chapter 9.)
If you attach any SCSI hard-disk drives to the host adapter card, connect the
hard-disk drive access cable to the SCSI host adapter card and to the AUX
LED connector on the system board (see Figure 9-1).
For additional instructions on connecting SCSI devices, see “SCSI Cables” found
earlier in this section.
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. Attach the other end
of the external SCSI cable to the SCSI connector on the system back panel.
NOTE: Dell offers an external SCSI 68-pin-to-50-pin adapter kit for connecting
SCSI-3 devices to the SCSI-2 connector on the Precision 610 system back panel.
Contact your Dell sales representative for more information.
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.
For instructions, see “Removing and Replacing the Front Bezel” and “Removing
and Replacing Front-Panel Inserts” found earlier in this chapter.
