Installing Drives: Dell OptiPlex GX1 Low-Profile Managed PC Systems

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-BoardExpansion-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 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.

9. Connect the SCSI device(s) to power.
