Notes: X indicates a populated DIMM slot. If adding four DIMMs (with two CPUs in- stalled), the configuration in rows 2 and 6 (with DIMMs spread over both CPUs) will result in optimized performance.

5-7 Adding PCI Cards

1. PCI slots

The H8DCR-3 has two PCI-Express x8 slots, one 133 MHz PCI-X slot and one 100 MHz PCI-X expansion slots. Two riser cards are included with the server to make two of these slots available in a 1U chassis format: one full height, half length Universal 133 MHz PCI-X or PCI-Express x8 add-on card and one low-profi le Universal 100 MHz PCI-X slot or PCI-Express x8 add-on card.

2. PCI card installation

Before installing a PCI add-on card, make sure it conforms to the correct riser card (see step 1, above).

Begin by swinging the release tab on the PCI shield that corresponds to the riser card/PCI-X slot you wish to populate. Insert the PCI card into the correct riser card (depending on whether it is a standard or low-profi le card), pushing down with your thumbs evenly on both sides of the card. Finish by pushing the release tab back to its original (locked) position. Follow this procedure when adding a card to either slot.
