Cards

WARNING: Before working inside your computer, read the safety information that shipped with your computer. For additional safety best practices information, see the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.

CAUTION: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.

CAUTION: Installing filler brackets over empty card-slot openings is necessary to maintain FCC certification of the computer. The brackets keep dust and dirt out of your computer and maintains the airflow that cools your computer.

Your Dell™ computer provides the following connectors on the system board for PCI and PCI Express cards:

• Two connectors for low-profile PCI cards
  
  
• One connector for a low-profile PCI Express x16 card
  
  

NOTE: Your Dell computer includes only PCI and PCI Express card connectors. ISA cards are not supported.

PCI Cards

Installing a PCI Card

If you are replacing a PCI card, remove the current driver for the card from the operating system. See the documentation that came with the card for information.

1. Follow the procedures in Working on Your Computer.
   
   
2. Remove the computer cover (see Removing the Computer Cover).
   
   
3. Gently lift the release tab on the card-retention latch all the way up.
   
   

1	card	2	retention latch
3	system board connector	4	release tab

4. If you are installing a card in an empty card connector on the system board, remove the filler bracket to create a card-slot opening at the back of the computer. Then continue with step 6.
   
   
5. If you are installing a card to replace one already installed in the computer, remove the installed card (see Removing a PCI Card).
   
   
6. Prepare the card for installation.
   
   

NOTE: See the documentation that came with the card for information on configuring the card, making internal connections, or customizing it for your computer.

WARNING: Some network adapters automatically start the computer when they are connected to a network. To guard against electrical shock, be sure to unplug your computer from its electrical outlet before installing any cards.

7. If you are installing a PCI Express x16 card, hold the securing-tab release lever away from the card connector as you insert the new card into the connector slot.
   
   
8. Place the card in the connector and press down firmly. Using the following illustration as a guide, ensure that the card is fully seated in the slot.
   
   

1	card fully seated	2	card not fully seated
3	bracket within slot	4	bracket caught outside of slot

NOTE: If you are installing a PCI Express x16 card, ensure that the securing tab on the connector's release lever fits into the notch on the front end of the card.

9. Gently rotate the release tab downward to move the card-retention latch into place to secure the cards.
   
   

CAUTION: Do not route card cables over or behind the cards. Cables routed over the cards can prevent the computer cover from closing properly or cause damage to the equipment.

10. Connect any cables that should be attached to the card.
    
    
11. Replace the computer cover (see Replacing the Computer Cover), reconnect the computer and devices to electrical outlets, and then turn them on.
    
    

CAUTION: To connect a network cable, first plug the cable into the network wall jack and then plug it into the computer.

12. If you installed a sound card:
    
    
    1. Enter system setup, select System Configuration® Miscellaneous Devices, and change the Audio setting to Disabled. (See Entering System Setup).
       
       
    2. Connect external audio devices to the sound card's connectors. Do not connect external audio devices to the microphone, speaker/headphone, or line-in connectors on the back panel of the computer.
       
       

CAUTION: If you disable the integrated network adapter, you will not have AMT functionality.

13. If you installed a network adapter card and want to turn off the integrated network adapter:
    
    
    1. Enter system setup, select System Configuration® Integrated NIC, and change the setting to Disabled (see Entering System Setup).
       
       
    2. Connect the network cable to the network adapter card's connectors. Do not connect the network cable to the integrated network connector on the back panel of the computer.
       
       
14. Install any drivers required for the card as described in the card documentation.
    
    

Removing a PCI Card

1. Follow the procedures in Working on Your Computer.
   
   
2. Remove the computer cover (see Removing the Computer Cover).
   
   
3. Gently rotate lift the release tab on the card-retention latch.
   
   

1	card	2	card-retention latch
3	system board connector	4	card insert
5	release tab

4. If necessary, disconnect any cables connected to the card.
