Installing and Removing a PCI Express x16 Card
CAUTION
When installing any PCI Express x16 card on the desktop board, ensure that it is fully seated in the
PCI Express x16 connector before you power on the system. If the card is not fully seated in the
PCI Express x16 connector, an electrical short may result across the PCI Express x16 connector
pins. Depending on the over-current protection of the power supply, certain board components
and/or traces may be damaged.
The desktop board has an integrated PCI Express x16 card retention mechanism (RM).
Installing a PCI Express x16 Card
Use the PCI Express x16 slot indicated in Figure 18 if you are using only one video card. Follow
these instructions to install a PCI Express x16 card:
1. Observe the precautions in "Before You Begin" on page 23.
2. Place the card in the PCI Express x16 connector.
3. Press down on the card until it is completely seated in the PCI Express x16 connector and the
card retention notch snaps into place around the RM pin.
4. Secure the card’s metal bracket to the chassis back panel with a screw.
