5-7 Adding PCI Cards
1. Expansion slots
The P8SCi has two PCI-Express x1 slots, one 64-bit 133 MHz PCI-X slot and
one 32-bit PCI slot. A riser card designed specifically for use in the
SC811T-260 chassis is included with your system. This riser card allows
an installed PCI card to sit at a 90 degree angle so it can fit inside the
chassis. This riser card accommodates 64-bit PCI-X cards and is installed
in the 133 MHz PCI-X slot (see Figure 5-4).
2. PCI card installation
Before installing a PCI add-on card, locate the PCI riser card mentioned in
Step 1. Begin by removing the shield for the PCI slot you wish to populate.
Fully seat the PCI card into the riser card and screw it into the metal reten-
tion rail. Then, insert the riser card into the PCI slot on the motherboard,
pushing down with your thumbs evenly on both sides of the card. Finish by
using a screw to secure the top of the card shield to the rear of the
chassis. The expansion slot shields protect the motherboard and its com-
ponents from EMI and aid in proper ventilation, so make sure there is al-
ways a shield covering each unused PCI slot.
