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.

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