7-8 Dell OptiPlex GXa Mini Tower Systems Reference and Installation Guide
•If you did not purchase the drive from Dell, call the
drive manufacturer.
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.”)
Installing an EIDE Hard-Disk Drive in the Hard-Disk Drive Bracket
Install an EIDE hard-disk drive in the hard-disk drive
bracket as follows:
1. If you are replacing a hard-disk drive that con-
tains data you want to keep, be sure to make a
backup of your files before you begin this
procedure.
2. Prepare the drive for installation.
Check the documentation that accompanied the drive
to verify that it is configured for your computer
system.
3. Remove the computer cover as instructed in
“Removing the Computer Cover” in Chapter 5.
4. 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 7-10). Lift the bracket up
slightly to free its hinge tabs from the chassis slots.

5. Slid e 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 7-11).
6. 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 7-11). If you are installing a drive in the
1-inch bay, use the four screw holes in the bottom of
the bracket.
CAUTION: Ground yourself by touching an
unpainted metal surface on the back of the
computer.
CAUTION: 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 cush-
ion it.
CAUTION: See “Protecting Against Electro-
static Discharge” in the safety instructions at
the front of this guide.
