in the contact edge of the PCI card. 

5. Lower the PCI card squarely into the PCI riser card so that the notch in the PCI card lines up with 

the notch in the PCI riser card. Slide the contacts straight into the PCI riser card and make sure 
the contacts are firmly seated. (

see 

Figure 11: PCI card installation 

on page 17).

 When properly 

seated, the contacts on the bottom should not be visible. Secure the PCI card to the chassis with 
the retaining screw.
