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 connector, an electrical short may result across the PCI Express connector pins.
Depending on the over-current protection of the power supply, certain board components and/or
traces may be damaged.
