7-4 Dell OptiPlex GXa Mini Tower Systems Reference and Installation Guide
To install a drive in a 5.25-inch drive bay, follow these
steps:
1. Unpack the drive and prepare it for installation.
Check the documentation that accompanied the drive
to verify that the drive is configured for your com-
puter system. Change any settings necessary for your
configuration.
NOTE: If you are installing a non-EIDE tape drive,
check the documentation for the drive to determine
the jumper or switch settings used to designate the
drive as drive address DS4 (not DS2 or DS3 as may
be indicated in the drive documentation). Unless the
drive is already set to drive 4, reconfigure its jumper
or switch setting (see “Jumpers” and “ Switches” in
Chapter 5).
If you are installing an EIDE CD-ROM or EIDE tape
drive, configure the drive for the Cable Select
setting.
2. Remove the computer cover as instructed in
“Removing the Computer Cover” in Chapter 5.
3. Remove the front bezel according to the instruc-
tions in “Removing and Replacing the Front
Bezel” found earlier in this chapter.
4. Remove the drive bracket from the bay you want
to use.
Squeeze the metal tabs that extend from each side of
the drive bracket toward each other, and pull the
bracket out of the bay (see Figure 7-6).
NOTE: For easier access inside the chassis, you may
want to rotate the power supply out of the way tem-
porarily. To do so, see “Rotating the Power Supply
Away From the System Board” in Chapter 5.
If a drive is already installed in the bay and you are
replacing it, be sure to disconnect the DC power
cable and interface cable from the back of the drive
before sliding the bracket out of the bay. To remove
the old drive from the bracket, turn the drive/bracket
assembly upside down and unscrew the four screws
that secure the drive to the bracket (see Figure7-7).
5. Attach the bracket to the new drive.
Turn the drive upside down and locate the four screw
holes around its perimeter. Fit the bracket over the
drive, and then tilt the front of the drive up so that
the bracket drops down into place. To ensure proper
installation, all screw holes should be aligned and
the tabs on the front of the bracket should be flush
with the front of the drive (see Figure 7-7).
CAUTION: Ground yourself by touching an
unpainted metal surface on the back of the
computer.
CAUTION: See “Protecting Against Electro-
static Discharge” in the safety instructions at
the front of this guide.
