Expansion Cards: Dell™ OptiPlex™ GX110 System User's Guide

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."

1. 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.

2. Unscrew and remove the metal filler bracket that covers the card-slot opening for the expansion-card connector you intend to use (see Figure 9).

   Save the screw for use when you install the expansion card later in this procedure.

3. Insert the expansion card into the expansion-card connector.

1. 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.
   
   
2. Insert the card's edge connector firmly into the expansion-card connector.
   
   
3. Gently rock the card into the connector until it is fully seated (see Figure 10, Figure 11, Figure 12, or Figure 13 for instructions for the small-form-factor, low-profile, midsize, and mini tower chassis, respectively).

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."

1. Remove the computer cover according to the instructions in "Removing and Replacing the Computer Cover."

2. If necessary, disconnect any cables connected to the card.
   
   
3. Unscrew the mounting bracket of the card you want to remove.
   
   
4. Grasp the card by its outside corners, and ease it out of its connector.
   
   
5. 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.

6. 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.

7. 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.
