To configure and install one or more SCSI devices, perform the following steps:
1. Determine which connector on the internal SCSI cable you will attach to each
SCSI device (refer to "SCSI Configuration Guidelines" found earlier in this
section).
2. Unpack each SCSI device and prepare it for installation.
Configure the device for a SCSI ID number and termination, if necessary. For
instructions, refer to the documentation that came with the SCSI device as well
as "SCSI Configuration Guidelines" found earlier in this section.
3. Install the SCSI devices as appropriate.
To install a SCSI hard-disk drive, complete steps 2, 3, and 5 of "Primary Hard-Disk
Drive Bay" or steps 2 through 7 of "Secondary Hard-Disk Drive Bay" found ear-
lier in this chapter. Then continue with step 4 of this procedure.
To install a 5.25-inch SCSI tape drive, CD-ROM drive, Zip drive, or digital audio
tape (DAT) drive, complete steps 2 through 4 and step 6 of "5.25-Inch Drive Bay"
found earlier in this chapter. Then continue with step 4 of this procedure.
To install a 3.5-inch SCSI tape drive, complete steps 2 through 6 and step 8 of
"Upper 3.5-Inch Bay" or steps 2 through 5 and step 7 of "Lower 3.5-Inch Bay
(Mini Tower Chassis Only)" found earlier in this chapter. Then continue with
step 4 of this procedure.
To install an external SCSI tape drive, continue with step 4 of this procedure.
4. If you are installing a SCSI host adapter card, configure and install it in an expan-
sion slot now. If a SCSI host adapter card is already installed, remove,
reconfigure, and reinstall the card at this time.
For instructions on configuring the card, refer to the documentation that came
with the card as well as "SCSI Configuration Guidelines" found earlier in this sec-
tion. For instructions on removing and installing the card, refer to "Expansion Card
Upgrades" in Chapter 2.
If you are installing a hard-disk drive, connect the thin access indicator cable to
the SCSI host adapter card and to the J8J1 connector on the system board (see
Figure 2-5). This cable carries a signal from the SCSI host adapter card to the
hard-disk drive access indicator on the computer's front panel whenever a SCSI
hard-disk drive is accessed.
5. Attach the SCSI cable to each SCSI device.
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 raised area on
the outside of the header connector fits into a notch on the device connector. The
connectors on wide SCSI cables are shaped so that they can be attached one
way only.
