Removing an Expansion Card

Follow this general procedure to remove an expansion
card:
1. If you are removing a non-Plug and Play 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.
CAUTION: See "Protecting Against Electro-
static 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 Chap-
ter 5.
5. 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 com-
puter and peripherals to their power sources, and
turn them on.
A
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: Do not use 32-MB DIMMs from the
Dell OptiPlex GXpro that contain a silver sticker
with the designation Kmm373F000Ak-6 in your
OptiPlex GXi system. These DIMMs may not work
reliably or will not be recognized in your OptiPlex
GXi system.
