Installing I/O Cards
To install an I/O card into your system unit, follow these steps.
NOTE Slots two and four are the graphics card slots. The primary graphics card
slot is slot number two and the secondary graphics card slot is slot
number four.
1. Open the left side panel of the system unit as explained in the section
“Opening the Left Side Panel of the System Unit” in this chapter.
2. Locate the appropriate slot for the I/O card that is to be installed. See
Figure 5-5.
3. Unscrew the T-15 Torx screw and remove the bulkhead blank of the
slot you have chosen. If no blank is present, you may skip to step four.
4. Pull evenly in the direction of the arrow on both PULL tabs of the I/O
card retainer to remove it. See Figure 5-7.
5. Insert the I/O card into the slot you have chosen with the bulkhead
appropriately positioned. See Figure 5-8. If the card is full length, the
non-bulkhead end of the card should be placed in the I/O card guide.
Press firmly and evenly on the I/O card until it is in the connector.
Screw the T-15 Torx screw into the I/O card’s bulkhead using 6
inch-pounds of torque. This will secure the I/O card.
6. Replace the I/O card retainer by placing the bottom retainer hook in
the slot on the air divider and the clips on the PULL tabs into their
slots on the chassis wall. See Figure 5-7.
7. Close the left side panel of the system unit by following the procedure
in the section “Closing the Left Side Panel of the System Unit” in this
chapter.
