 Video CardReplacement Note:  Install an AGP card in slot 1 only. Install PCI cards in the slots 
labeled PCI 2, 3, 4, and 5.
Warning: Cables with large connectors may interfere with the enclosure in the PCI slot 
numbered 5, making it difficult to close the door and potentially causing damage to the PCI 
card. If this is the case, rearrange the cards in the slots. You may also connect the cable 
after the enclosure door is shut, but be sure to remove the cable before opening the door 
again. If the PCI cards are connected to each other with cables or jumpers, take care 
when closing the door.
