5-6 Adding PCI Cards
1. PCI Expansion Slot s
The X7DBR-3/X7DBR-E has two Universal PCI slots, each of which support either
one x8 PCI-Express card or one PCI-X 133/100 MHz card. (On the X7DBR-3, slot
#7 is a 100 MHz PCI-X slot, on the X7DBR-E slot #7 is a 133 MHz PCI-CX slot.)
The SC815TQ-560 chassis can accommodate one standard size (full height full
length) and one low profi le PCI expansion cards. When viewed from the chassis
front, the standard size card installs to the left and the low-profi le card installs to
the right side.
PCI cards are installed into riser cards that have been included with the system: the
CSE-RR1U-X riser supports a standard size card in slot #6 and the CSE-RR1U-XLP
riser supports a low profi le card in slot #7.
An additional two rise r card s are availab le as an opt ion to sup por t add- on c ards
in the SXB-E1 and SXB-E2 x8 ( PCI- Expr ess) slots: the CS E-RR1U- EL riser (fo r
a standard size card) and the CSE- RR1U- ELP (for a low p rofi le card).
2. PCI card installation
Before installing a PCI add-on card, make sure you install it into the correct riser
card. Begin by releasing the locking tab that corresponds to the slot you wish to
populate. Insert the expansion card into the correct riser card, pushing down with
your thumbs evenly on both sides of the card.
