Removing an Expansion Card Follow this general procedure to remove an expansion card: 1. If you are removing an ISA expansion card, enter the ICU and remove the expansion card from your configuration. See Chapter 3, "Using the ISA Configuration Utility," for instructions. 2. Remove the computer cover according to the instructions in "Removing the Computer Cover" in Chapter 5. CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions at the front of this guide. 3. If necessary, disconnect any cables connected to the card. 4. Remove the expansion-card cage as instructed in "Removing the Expansion-Card Cage" in Chapter 5. 5. Position the expansion-card cage so that the riser board lies horizontally on your work surface, and unscrew the mounting bracket of the card you want to remove. 6. Grasp the card by its outside corners, and ease it out of its connector. 7. If you are removing the card permanently, install a metal filler bracket over the empty card-slot opening. NOTE: Installing filler brackets over empty card-slot openings is necessary to maintain Federal Communications Commission (FCC) certification of the system. The brackets also keep dust and dirt out of your computer. 8. Replace the expansion-card cage in the chassis as instructed in "Replacing the Expansion-Card Cage" in Chapter 5. 9. Replace the computer cover; reconnect your computer and peripherals to their power sources, and turn them on. Adding Memory Memory can be increased to a maximum of 512 megabytes (MB) by installing combinations of 8-, 16-, 32-, 64-, or 128-MB dual in-line memory modules (DIMMs) in the four DIMM sockets on the system board. Figure 6-6 shows the DIMMs and DIMM sockets.

Removing an Expansion Card
Follow this general procedure to remove an expansion
card:
1.
If you are removing an ISA expansion card, enter
the ICU and remove the expansion card from
your configuration.
See Chapter 3, “Using the ISA Configuration Util-
ity,” for instructions.
2.
Remove the computer cover according to the
instructions in “Removing the Computer Cover”
in Chapter 5.
3.
If necessary, disconnect any cables connected to
the card.
4.
Remove the expansion-card cage as instructed in
“Removing the Expansion-Card Cage” in Chap-
ter 5.
5.
Position the expansion-card cage so that the riser
board lies horizontally on your work surface, and
unscrew the mounting bracket of the card you
want to remove.
6.
Grasp the card by its outside corners, and ease it
out of its connector.
7.
If you are removing the card permanently, install
a metal filler bracket over the empty card-slot
opening.
NOTE: Installing filler brackets over empty card-slot
openings is necessary to maintain Federal Commu-
nications Commission (FCC) certification of the
system. The brackets also keep dust and dirt out of
your computer.
8.
Replace the expansion-card cage in the chassis as
instructed in “Replacing the Expansion-Card
Cage” in Chapter 5.
9.
Replace the computer cover; reconnect your com-
puter and peripherals to their power sources, and
turn them on.

dding Memory
Memory can be increased to a maximum of 512 mega-
bytes (MB) by installing combinations of 8-, 16-, 32-,
64-, or 128-MB dual in-line memory modules (DIMMs)
in the four DIMM sockets on the system board.
Figure 6-6 shows the DIMMs and DIMM sockets.
Your system can support both error correction code
(ECC) and non-ECC extended-data out (EDO) DIMMs.
However, ECC support is available only if all DIMMs
are ECC DIMMs. ECC DIMMs enable your system to
correct all single-bit memory errors and detect multibit
memory errors.
Figure 6-6.
DIMMs and DIMM Sockets
Table 6-1 lists sample memory configurations and shows
valid DIMM combinations and socket placement for each
configuration.
CAUTION: See “Protecting Against Electro-
static Discharge” in the safety instructions at
the front of this guide.
CAUTION: Do not use 32-MB DIMMs from the
Dell OptiPlex GX
pro
that contain a silver sticker
with the designation Kmm373F000Ak-6 in your
OptiPlex GX
i
system. These DIMMs may not work
reliably or will not be recognized in your OptiPlex
GX

system.
