Guidelines ."
3. Remove the computer cover as instructed in " Removing the Computer Cover ."
4. If you are installing a SCSI host adapter card, configure the adapter card.
For instructions on configuring the card, see the documentation that came with the adapter card and
"
SCSI Configuration Guidelines ."
5. Install the SCSI devices as appropriate.
To install an internal SCSI hard-disk drive, complete steps 3 through 7 of " Installing an
EIDE Hard-Disk Drive in the Hard-Disk Drive Bracket ." Then continue with step 5 of this
procedure.
To install a SCSI tape drive, CD-ROM drive, or DAT drive, complete steps 2 through 6 of
"
Installing a Drive in a 5.25-Inch Drive Bay ." Then continue with step 5 of this procedure.
To install an external SCSI tape drive, continue with step 5 of this procedure.
6. If you are installing a new SCSI host adapter card, install it in an expansion slot now.
See " Installing an Expansion Card ."
If a SCSI host adapter card is already installed, remove, reconfigure, and reinstall the card at this time.
See the documentation that came with the SCSI host adapter card, "
Removing an Expansion Card ,"
and " Installing an Expansion Card ."
Connect the hard-disk drive access cable to the SCSI host adapter card and to the HDLED connector
on the riser board (see "
Riser-Board Expansion-Card Connectors "). 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 one of the SCSI hard-disk drives is accessed.
7. Attach a SCSI cable to each SCSI device.
For additional instructions on connecting SCSI devices, see " SCSI Cable and SCSI Termination ."
NOTICE: You must match the colored strip on the cable with pin 1 on the drive's interface
connector to avoid possible damage to your system.
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 connector. 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.
8. Attach the SCSI cable to the connector on the SCSI host adapter card.
NOTICE: You must match the colored strip on the internal SCSI cable with pin 1 on the adapter
card connector to avoid possible damage to your system.
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
