Hard-Disk Drives: Dell™ OptiPlex™ GX300 System User's Guide
Up to two enhanced integrated drive electronics (EIDE) drives (one of which must be 1
inch high or less) can be installed in the hard-disk drive bracket below the drive cage.
The first EIDE drive is installed in the 1-inch (lower) drive bay labeled "HD1";
a second drive is installed in the 1.6-inch bay labeled "HD2."
All EIDE devices should be configured for the Cable Select jumper position, which
assigns master and slave status to devices by their position on the interface cable. When
two EIDE devices are connected to a single EIDE interface cable and are configured for the
Cable Select jumper position, the device attached to the last connector on the interface
cable is the master or boot device (drive 0), and the device attached to the middle
connector on the interface cable is the slave device (drive 1). Refer to the drive
documentation in your upgrade kit for information on setting devices to the Cable Select
jumper position.
With the two EIDE interface connectors on the system board, your system can support up
to four EIDE devices. EIDE hard-disk drives should be connected to the EIDE interface
connector labeled "IDE1." EIDE tape drives and CD-ROM drives should be connected
to the EIDE interface connector labeled "IDE2."
To install an EIDE hard-disk drive in the hard-disk drive bracket, perform the
following steps.
- If you are replacing a hard-disk drive that contains data you want to keep, be sure to
make a backup of your files before you begin this procedure.
- Prepare the drive 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.
Check the documentation for the drive to verify that it is configured for your computer system.
- Remove the computer cover as instructed
in "Removing and Replacing the Computer Cover."
- Remove the drive bracket from the chassis.
If a hard-disk drive is already installed in the drive bracket,
disconnect the DC power cable and EIDE cable from the drive.
Remove the screw securing the hard-disk drive bracket to the drive cage in the chassis.
Grasp the bracket, and rotate it outward from the chassis until the sliding tab clears
the slide rail on the drive cage (see Figure 1). Lift the bracket up slightly to free its hinge tabs from the chassis slots.

- Slide the drive into the chosen bay of the bracket, oriented so that the
connectors on the back of the drive will face the back of the chassis when the bracket is
reinstalled (see Figure 2).
- Align the four screw holes of the drive and bracket. Insert and tighten
the screws that came with your upgrade kit.
If you are installing a drive in the 1.6-inch bay,
use the four screw holes in the side of the bracket (see Figure 2). If you are installing a drive
in the 1-inch bay, use the four screw holes in the bottom of the bracket.

- Reinstall the hard-disk drive bracket in the chassis
(see Figure 3).
Insert the bracket's hinge tabs into the chassis slots so
that the tabs hook over the slots. Then rotate the bracket toward the drive cage,
and fit the bracket's sliding tab on the drive-cage slide rail. Slide the bracket
into place. Reinstall the screw you removed in step 4.

- Connect a DC power cable to the power input connector on the back
of the drive (see Figure 4).
Check all connectors to be certain that they are properly
cabled and firmly seated.
- Connect one of the device connectors on the EIDE cable to the
40-pin interface connector on the back of the hard-disk drive.
NOTICE: You must match the colored strip on the EIDE cable
with pin 1 on the drive's interface connector to avoid possible damage to your system.
|
NOTE: Ultra Advanced
Technology Attachment (ATA)/66 hard-disk drives require an 80-conductor cable to transfer
data at full speed. The 80-conductor cable has a 40-pin connector just like the Ultra
ATA/33 cable but has twice as many wires within the cable itself. If you use an Ultra
ATA/33 cable with Ultra ATA/66 hard-disk drives, they will transfer data at Ultra ATA/33
speeds.

- If it is not already connected, connect the other end of the EIDE
cable to the IDE1 connector on the system board.
NOTICE: You must match the colored strip on the EIDE cable
with pin 1 on the IDE1 connector to avoid possible damage to your system.
To locate the IDE1 connector,
see Figure 3
in "Inside Your Computer."
- Replace the computer cover. Then reconnect your computer and
peripherals to their power sources, and turn them on.
- Insert a bootable system diskette into drive A, and restart the
computer.
- Turn on the computer system.
- Enter System Setup, and
update Primary Drive 0
or Primary Drive 1.
After you update the System Setup settings, reboot the system.
- Partition and logically format your drive before proceeding to the next step.
See the documentation for your operating system for instructions.
- Test the hard-disk drive by running the Dell Diagnostics.
- If the drive you just installed is the primary drive, install your operating
system on the hard-disk drive.
Refer to the documentation that came with your operating system.
This section describes how to configure and install small computer system interface
(SCSI) devices in your system.
Up to two SCSI hard-disk drives can be installed in the hard-disk
drive bracket. Although you install SCSI devices essentially the same way as other
devices, their configuration requirements are different. For details on configuring your
particular SCSI subsystem, refer to the documentation for your SCSI devices and/or your
host adapter card. The following subsections offer some general guidelines.
|
|
NOTE: Dell does not support
mixing SCSI and EIDE hard-disk drives in the same system. If your system contains any EIDE
hard-disk drives, do not install SCSI hard-disk drives.
|
Internal SCSI devices must have a unique SCSI ID number from 0 to 15.
When SCSI devices are shipped from Dell, the default SCSI ID numbers for the primary
and secondary controllers are assigned as follows:
- SCSI controller: SCSI ID 7
- Boot SCSI hard-disk drive: SCSI ID 0
- SCSI CD-ROM drive: SCSI ID 5
- SCSI tape or digital audio tape (DAT) drive: SCSI ID 6
|
|
NOTE: There is no requirement
that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in
order by ID number.
|
SCSI devices installed by Dell are configured correctly during
the manufacturing process. You do not need to set the SCSI ID for these SCSI devices.
If you attach additional optional SCSI devices, refer to the
documentation for each device for information about setting the appropriate SCSI ID number.
NOTICE: Dell recommends that you use only SCSI cables
purchased from Dell. SCSI cables purchased elsewhere are not guaranteed to work with Dell
systems.
SCSI logic requires that termination be enabled for the two devices
at opposite ends of the SCSI chain and disabled for all devices in between.
See the documentation provided with any optional SCSI device you
purchase for information on disabling termination on the device.
Ultra2/Wide low-voltage differential (LVD) devices
(hard-disk drives) use a 68-pin cable. One end of this cable should be
attached to the SCSI controller card. The remaining connectors on the cable
should be attached to the various LVD devices.
Narrow SCSI devices (tape drives, CD-ROM drives, and some
hard-disk drives) use a 50-pin cable. One end of this cable should be attached to
the SCSI controller card. The remaining connectors on the cable should be attached
to the various Narrow SCSI devices.
Configure and install one or more SCSI devices in your computer as follows:
- Determine which connector on the internal SCSI
cable you will attach to each SCSI device.
- 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.
- Install the SCSI devices as appropriate.
- 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").
- 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.
- 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.
- 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.
- Replace the computer cover. Then reconnect your
computer and peripherals to their power sources, and turn them on.
|
|
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.
|
- To reset the chassis intrusion detector, enter System Setup and reset
Chassis Intrusion to Enabled or Enabled-Silent.
See "Chassis
Intrusion" for instructions.
|
|
NOTE: If a setup password has
been assigned by someone else, contact your network administrator for information on
resetting the chassis intrusion detector.
|
- 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.
- 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.
- Test the SCSI devices.
Test a SCSI hard-disk drive by running the Dell Diagnostics.
To test a SCSI tape drive, refer to the documentation for the tape drive software to
perform a tape drive backup and verification test.
You may need to use different programs than those provided with the operating system to
partition and format SCSI hard-disk drives. Refer to the documentation that came with your
SCSI software drivers for information on installing the appropriate drivers and preparing
your SCSI hard-disk drive for use.
