5-6 Adding PCI-E Add-On Cards
The SC748TQ-R1K43BP chassis can accommodate all the card slots of the
X9QRi-F+/X9QR7-TF+ serverboard (two (2) PCI Express 3.0 x16 slots and two (2)
PCI Express 3.0 x8 in x 16 slots).
Installing an Add-on Card
1. Begin by removing the PCI slot shield for the slot you wish to populate.
2. Fully seat the card into the riser card slot, pushing down with your thumbs
evenly on both sides of the card.
3. Finish by using a screw to secure the top of the card shield to the chassis.
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.
