Installing and Removing a PCI Express x16
Card
CAUTION
When installing a PCI Express x16 card on the Desktop Board, ensure that the card 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 Desktop Board components and/or traces may be damaged.
