5-6 Adding PCI Cards
1. PCI Expansion Slots
The X7DB3 has six PCI expansion slots, which includes two x8 PCI-Express slots,
one x4 PCI-Express slot, two PCI-X 133 MHz slots and one PCI-X 100 MHz slot.
The SC825TQ-560LP/SC825TQ-R700LP chassis can accommodate up to seven
low-profi le PCI expansion cards. PCI cards are installed directly to the serverboard
(riser cards are not needed).
2. PCI Card Installation
Before installing a PCI add-on card, make sure you install it into a slot that supports
the speed of the card (see step 1, above). Begin by removing the screw that se-
cures the PCI slot shield to the chassis. Insert the expansion card into the correct
slot on the serverboard, pushing down with your thumbs evenly on both sides of the
card. Finish by securing it to the IO backplane with the screw you removed from
the shield. Follow this procedure when adding a card to other slots.
