Expansion Cards
Expansion cards are installed on the computer's riser board (see Figure 3). The riser board plugs into the
RISER connector on the system board (see
Figure 1) and is considered an extension of the system board.
The system accommodates up to five expansion cards, which can be a mix of 32-bit PCI expansion cards,
and 8- and 16-bit ISA expansion cards. (See Figure 2 for examples of ISA and PCI expansion cards.)

Expansion Slots
Two riser board options are available (Figure 3).
With the active riser board option, seven expansion-card connectors reside on the riser board.
Because two expansion slots are shared, a maximum of five expansion cards can be installed on the
riser board.
Expansion-card connectors ISA1–ISA2 support 8- or 16-bit ISA expansion cards.
Expansion-card connectors PCI1–PCI5 support 32-bit PCI expansion cards.
With the passive riser board option, six expansion-card connectors reside on the riser board. Because
one expansion slot is shared, a maximum of five expansion cards can be installed on the riser board.
Expansion-card connectors ISA1–ISA3 support 8- or 16-bit ISA expansion cards.
Expansion-card connectors PCI1–PCI3 support 32-bit PCI expansion cards.
NOTE: On shared expansion slots, only one card of either type can be installed in the common slot.
