Adding PCI Expansion Cards
The SC813MTQ-300C chassis can accommodate one full-size PCI-Express, PCI-X
or PCI expansion card with the use of a riser card.
Installing an Add-on Card
1.
After powering down the system, remove the PCI slot shield.
2.
Fully seat the riser card into the slot, pushing down with your thumbs evenly
on both sides of the card. Seat the expansion card into the riser card.
3.
Finish by using a screw to secure the top of the card shield to the chassis.
The PCI slot shield protects the serverboard and its components from EMI
and aid in proper ventilation, so make sure it is always in place.
