5.6 Adding PCI Add-on Cards
The R423-E3 server can accommodate seven low-profile PCI add-on cards.
5.6.1 Installing an Add-on Card
1. Begin by removing the shield for the PCI slot you wish to populate.
2. Fully seat the card into the 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 shield protects the serverboard and its components from EMI and aid in proper
ventilation, so make sure there is always a shield covering each unused slot.
