Mac Pro Take Apart — PCI Express/Graphics Card 25
Procedure
This procedure explains how to remove a standard card and a card that includes a booster cable.
Before you can remove either type of card, however, you must rst loosen the two captive screws
that secure the PCI bracket to the enclosure and remove the bracket.
Warning: When removing or installing a card, handle it only by the edges. Do not touch its
connectors or any of the components on the card. Lift the card straight out from the connector
to remove it, and insert it straight into the connector to install it. Do not rock the card from side
to side and don’t force the card into the slot. Once the replacement card is installed, pull on it
gently to check that it is properly connected.
