PCI and PCI-X adapters
This section provides information about the expansion slots on the system board and
peripheral component interconnect (PCI or PCI-X) adapters.
The following illustration shows the location of the PCI-X expansion slots on the PCI-X
board.
Note: The illustrations in this document might differ slightly from your hardware.
PCI and PCI-X adapter considerations
Before you install adapters, review the following:
• Locate the documentation that comes with the adapter and follow those instruc-
tions in addition to the instructions in this chapter.
• If you need to change the switch settings or jumper settings on your adapter, fol-
low the instructions that come with the adapter.
• Video adapters are not supported.
• Some long adapters have extension handles or brackets installed. Before install-
ing the adapter, you must remove the extension handle or bracket.
• You can install both PCI and PCI-X adapters in the same bus. However, if you
install a PCI adapter and a PCI-X adapter in the same bus, the PCI-X features of
the PCI-X adapter will be disabled and the adapter will function as a PCI adapter.
• You can install PCI or PCI-X adapters of speeds faster than what is labeled for a
particular PCI-X bus. For example, if you install two 133 MHz adapters into slots
that are labeled as 100 MHz slots, the adapters will operate at 100MHz.
• If you install a 33 MHz and a 66 MHz adapter in the same bus, the bus speed will
match that of the slowest adapter.
