Replacing a PCI/PCI Express Card 33
CAUTION: Ensure that you release the securing tab to seat the card. If the card is
not installed correctly, you may damage the system board.
Gently pull the securing tab (if present) and place the card in the
connector. Press down firmly and ensure that the card is fully seated in the
slot.
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.
CAUTION: An incorrectly attached graphics power cable may result in degraded
graphics performance.
8 Screw in the card retention screw(s) on the top of the card retainer at the
appropriate card slot.
9 Repeat for additional graphics cards.
Connect the PCIe supplementary power connectors from the system
power supply to each of the graphics cards. See the documentation for the
card for information about the card’s cable connections.
10 Install the NVIDIA SLI connector across the two outer graphics cards.
Each SLI-ready graphics card has an SLI connector tab on its upper side.
Press firmly on each connector so that it completely covers the connector
tab.
