5-7 Adding PCI Cards
1. PCI slots:
The H8DA8 has six PCI expansion slots, which includes two 64-bit 133 MHz PCI-X
slots, two 64-bit 66 MHz PCI-X slots and two 32-bit 33 MHz PCI slots. (The 66 MHz
PCI-X #3 slot supports Zero Channel RAID.)
The SC743S1-R760 chassis allows all six slots to be populated with standard size
(full height, full-length) PCI cards. PCI cards are installed directly to the serverboard
(riser cards are not needed).
2. PCI card installation:
Before installing a PCI add-on card, make sure you install it into a slot that supports
the speed of the card (see step 1, above). Begin by removing the screw from the
PCI shield that corresponds to the slot you wish to populate. Insert the PCI card
into the correct slot on the serverboard, pushing down with your thumbs evenly on
both sides of the card. Finish 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 other slots.
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.
