Expansion-Card Riser-Board Components and PCI Buses
There are two expansion card configurations for this systems. Each riser (center riser and left riser) contains
one slot for either a PCI-X configuration or a PCIe configuration. This system supports only one
configuration (PCI-X or PCIe) for both risers. Figure 6-6 and Figure 6-7 show the components on the
optional PCI-X expansion-card riser boards, including the expansion-card slots and buses. "PCIe Riser
Board Expansion Slots" on page 61 and "PCI-X Riser Board Expansion Slots" on page 61 list the PCI bus
and operating speed for each expansion-card slot.
NOTE: Because the orientation and physical connectors are similar, the PCIe expansion card configuration is not
shown.
