The PCI-X based I/O system, an industry standard for connecting peripherals to a
processor, is the primary I/O system for the Origin 3900 server. The hardware
components of this I/O system are contained in IX- and PX- bricks. The IX-brick provides
the base I/O functionality for the server and 12 PCI/PCI-X slots. One of the 12 slots is
reserved for a system PCI card. If additional PCI slots are required beyond the 11
remaining slots in the IX-brick, PX-bricks are configured into the server. Each PX-brick
provides an additional 12 PCI/PCI-X slots.
For instructions on how to install or remove PCI cards, see "Installing or Replacing PCI
or PCI-X Card" on page 202.
