5-7 Adding
PCI
Cards
1. PCI slots:
The H8DSR-8 has four PCI expansion slots, which includes two x8 PCI-Express,
one 64-bit 133 MHz PCI-X and one 64-bit 100 MHz PCI-X slots. An additional slot
(slot #7) supports a low profi le IPMI 2.0 card.
The 1020S-8 includes two riser cards to accommodate up to two PCI-X/PCI-E cards
in the following confi guration: one low profi le expansion card (PCI-X 133 MHz or
PCI-Express x8) and one full-height, half-length expansion card (PCI-X 100 MHz
or PCI-Express x8).
2. PCI card installation:
Before installing a PCI add-on card, make sure you install it into the appropriate
riser card. Begin by removing the screw from the backpanel PCI slot shield that
corresponds to the slot you wish to populate. Insert the PCI card into the correct
riser card, pushing down with your thumbs evenly on both sides of the card. Fin-
ish by securing the card to the chassis with the same screw you removed from
the PCI shield. Follow this procedure when adding a card to the other riser card.
Note: the PCI slot shields help promote proper airlow in the chassis and shield the
inside of the system from EMI (electromagnetic interference). For these reasons,
make sure there is always a shield covering each unused slot.
Notes: X indicates a populated DIMM slot. If adding four DIMMs (with two CPUs in-
stalled), the confi gurations with DIMMs spread over both CPUs (and not like in row 5) will
result in optimized performance.
