5-7 Adding PCI Add-On Cards
The 8046B-TRLF can up to fi ve PCI add-on cards, as described below.
Installing an Add-on Card
Begin by removing the PCI slot shield for the slot you wish to populate. 1.
Fully seat the card into the riser card slot, pushing down with your thumbs 2.
evenly on both sides of the card.
Finish by using a screw to secure the top of the card shield to the chassis. 3.
The PCI slot shields protect the serverboard and its components from EMI
and aid in proper ventilation, so make sure there is always a shield covering
each unused slot.
