Expansion Cards: Dell™ OptiPlex™ GX100 System User's
Guide
OptiPlex GX100 systems can accommodate a mix of 32-bit Peripheral
Component Interconnect (PCI) expansion cards and, optionally, 16-bit and 8-bit
Industry-Standard Architecture (ISA) expansion cards, depending on the chassis and riser board. See
Figure 1 for examples of the expansion cards.

The expansion-card connectors are located on a riser board that
differs for each chassis:
 |
NOTE: If you choose one of the optional riser
boards with ISA expansion-card connectors, evaluate the performance of any ISA expansion
cards on a single system before you order other ISA riser boards. Dell recommends this
step due to the broad range of ISA implementations in the computer industry. |
The small-form-factor chassis riser board has two PCI expansion-card
connectors (see Figure 2).

The low-profile chassis is available with either a PCI riser board
(see Figure 3) or a PCI/ISA riser board (see Figure 4). The PCI riser board provides three PCI expansion
card slots. The PCI/ISA riser board provides one PCI expansion slot, one ISA expansion
slot, and one shared PCI/ISA expansion slot.

Mini Tower Chassis Riser Board
The mini tower chassis is available with either a PCI riser board
(see Figure 5) or a PCI/ISA riser board (see Figure 6). The PCI riser board provides five PCI expansion
card slots. The PCI/ISA riser board provides three PCI expansion slots, two ISA expansion
slots, and two shared PCI/ISA expansion slots.

To install an expansion card, perform the following steps.
 |
CAUTION: To avoid the possibility of electric shock, turn
off the computer and any peripherals, disconnect them from their electrical outlets, and
then wait at least 5 seconds before you remove the computer cover. Also, before you
install an expansion card, see the other precautions in "Safety First—For You and Your
Computer." |
- Prepare the expansion card for installation, and remove the computer
cover according to the instructions in "Removing and Replacing the Computer Cover."
- See the documentation that came with the expansion card for
information on configuring the card, making internal connections, or otherwise customizing
it for your system.
|
CAUTION: Some network cards automatically start up the
system when they are connected. To guard against electrical shock, be sure to unplug your
computer from its electrical outlet before you install any expansion cards. |
- Unscrew and remove the metal filler bracket that covers the card-slot
opening for the expansion-card connector you intend to use (see Figure 7).
Save the screw for use when you install the expansion card later in this
procedure.
Figure 7. Removing
the Filler Bracket
- Insert the expansion card into the expansion-card connector.
- If the expansion card is full-length, insert the front end of the
card into the corresponding card guide on the inside front of the chassis as you insert
the card into its connector.
- Insert the card's edge connector firmly into the expansion-card
connector.
- Gently rock the card into the connector until it is fully seated (see
Figure 8, Figure 9, or Figure 10 for instructions for the small-form-factor, low-profile, and mini tower
chassis, respectively).

- When the card is firmly seated in the connector, secure the card's
mounting bracket to the chassis with the screw you removed in step 2.
- Connect any cables that should be attached to the card.
See the documentation for the card for information about the card's cable
connections.
- Replace the computer cover, and reconnect your computer and
peripherals to their electrical outlets and turn them on.
|
NOTE: After you remove and replace the
cover, the chassis intrusion detector causes the following message to appear on the screen
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. |
While in System Setup, if you installed an entry-level OptiPlex
sound card, change the setting for Sound to Off.
To remove an expansion card, perform the following steps.
|
CAUTION: To avoid the possibility of electric shock, turn
off the computer and any peripherals, disconnect them from their electrical outlets, and
then wait at least 5 seconds before you remove the computer cover. Also, before you remove
or replace an expansion card, see the other precautions in "Safety First—For You and Your
Computer." |
- Remove the computer cover according to the instructions in "Removing and Replacing the Computer
Cover."
- If necessary, disconnect any cables connected to the card.
- Unscrew the mounting bracket of the card you want to remove.
- Grasp the card by its outside corners, and ease it out of its
connector.
- If you are removing the card permanently, install a metal filler
bracket over the empty card-slot opening.
|
NOTE: You must install filler brackets
over empty card-slot openings to maintain Federal Communications Commission (FCC)
certification of the system. The brackets also keep dust and dirt out of your computer. |
- Replace the computer cover, and reconnect your computer and
peripherals to their electrical outlets and turn them on.
|
NOTE: After you remove and replace the
cover, the chassis intrusion detector causes the following message to appear on the screen
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.
|
NOTE: If a setup password has been
assigned by someone else, contact your network administrator for information on resetting
the chassis intrusion detector. |
