PCI-X Riser Board Expansion Slots
The PCI-X riser configuration provides two PCI-X slots with the following features:
• Two PCI-X risers, installed in the left and center riser connectors.
• Two PCI-X 64-bit/133-MHz expansion slots (on separate buses).
• Support for full height/half-length PCI cards in both slots.
Expansion Card Installation Guidelines
NOTE: You cannot combine PCIe and PCI-X risers. Two risers must be installed or the system will not power up.
NOTE: The expansion-card slots are not hot-pluggable.
To identify expansion slots, see Figure 3-12. The two expansion card slots are on separate buses.
Installing an Expansion Card
