Did You Know?--Installing a Full-Length PCI Card It may be easier to install a PCI card if you remove the hard disk drives and carriers, and remove adjacent cards. If you have a full-length card, install the end of the card in the card guide first, and then align the card with the PCI slot to finish installing it. Secure the card with the PCI bracket. Insert the PCI bracket under the brace. Port access opening PCI Express slot If the PCI Express card you are installing is full-length (12 inches), make sure it fits in the appropriate card guide. Chapter 3 Working Inside Your Computer 49 7 Press the card gently but firmly until the connector is fully inserted. Press only on the bare areas of the card to avoid damaging the components. Note: Don't rock the card from side to side or force it. If you meet resistance, check the connector and slot for damage or obstructions, then try inserting the card again. 8 Pull the card gently to see if it is properly connected. If it stays in place and its gold connectors are barely visible, the card is connected. 9 Replace the PCI bracket and tighten the screw to secure the card. Warning: If you remove a card and don't install a replacement, place a port access cover over the empty slot to keep foreign objects out of the enclosure. An uncovered slot affects the airflow that cools the internal components and may cause damage. 10 Replace the side panel and push the latch down to secure it. Replacing the Internal Backup Battery Your Mac Pro uses a CR 2032 Lithium battery that preserves settings, such as the date and time, when your Mac Pro is off.
