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.
