Dell OptiPlex GX300 - Manual (Page 31)

1. Determine which connector on the internal SCSI cable you will attach to each SCSI device.
2. Unpack each SCSI device and prepare it for installation.
NOTICE: Ground yourself by touching an unpainted metal surface on the back of the computer.
NOTICE: When you unpack the drive, do not set it on a hard surface, which may damage the drive. Instead, set the drive on a
surface such as a foam pad that will sufficiently cushion it.
Configure the device for a SCSI ID number and disable termination, if necessary.
3. Install the SCSI devices as appropriate.
¡ To install a SCSI hard-disk drive, complete steps 3 through 9 of " Installing an EIDE Hard-Disk Drive ." Then continue with step 4 of this
procedure.
¡
To install a SCSI tape drive, CD-ROM drive, or DAT drive, complete installation steps 2 through 6 in " Diskette, Tape, and CD-ROM
Drives ." Then continue with step 4 of this procedure.
¡
To install an external SCSI device, continue with step 4 of this procedure.
¡ To install a SCSI host adapter card, configure the card and install it in an empty expansion slot (see " Installing an Expansion Card "). 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 3 in "Inside Your Computer").
4. Attach the SCSI cable to each SCSI device.
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.
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 LVD 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.
5. Connect the SCSI device(s) to power.
¡
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 provide airflow for the fan or cooling vents.
6. If you installed an externally accessible device, remove the front bezel and remove the front-panel insert for the drive bay from the front bezel.
Then replace the front bezel.
For instructions on removing the front bezel, see " Removing and Replacing the Front Bezel ." To remove a front-panel insert, hold the bezel
with the inside facing toward you and press each end of the insert with your thumbs until it snaps free of the bezel.
7. Replace the computer cover. Then reconnect your computer and peripherals to their power sources, and turn them on.
8. To reset the chassis intrusion detector, enter System Setup and reset Chassis Intrusion to Enabled or Enabled-Silent.
See "Chassis Intrusion" for instructions.
9. If necessary, update the drive system configuration information in System Setup.
After installing a SCSI hard-disk drive, Primary Drive 0 and Primary Drive 1 should be set to None. If you have any EIDE devices on the
second EIDE channel, such as a CD-ROM or tape drive, Secondary Drive 0 and/or Secondary Drive 1 should be set to Auto. If you have
any SCSI devices on the second EIDE channel, Secondary Drive 0 and/or Secondary Drive 1 should be set to None.
10. If you installed a SCSI hard-disk drive, partition and format the drive. Then install the operating system.
For instructions, see " Partitioning and Formatting SCSI Hard-Disk Drives " and your operating system documentation.
NOTE: After you remove and replace the cover, the chassis intrusion detector will cause the following message to be displayed at
the next system start-up:
ALERT! Cover was previously removed.
NOTE: If a setup password has been assigned by someone else, contact your network administrator for information on resetting
the chassis intrusion detector.
