Adding Pci Cards - Supermicro 7045B-T User Manual

Note: Due to memory allocation to system devices, memory remaining available
for operational use will be reduced when 4 GB of SDRAM is used. The reduction
in memory availability is disproportional. (Refer to the following Memory Availability
Table for details.

Adding PCI Cards

1. PCI Expansion Slots
The X7DBE 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 SC743TQ-650 chassis can accommodate up to six standard size PCI expan-
sion 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 from the
PCI slot shield that corresponds to the slot you wish to populate. Insert the expan-
sion card into the correct slot on the serverboard, pushing down with your thumbs
evenly on both sides of the card. Finish by securing the card to the chassis with
the same screw you removed from the PCI slot shield. Follow this procedure when
adding a card to other slots.
