PCI and PCI-X Card Configuration Guidelines
007-4377-002
The PCI-X slots are numbered bus 1 through bus 6. Each bus has two slots, labeled 1 and
2, as shown in Figure 6-5. Separate buses enable the IX-brick to run cards of different
frequencies at the same time. For example, bus 1 can have one 133-MHz card, bus 2 can
have two 66-MHz cards, bus 3 can have two 33-MHz cards, and so on.
The PCI-X bus supports 32-bit and 64-bit PCI or PCI-X cards at the same time.
For maximum bandwidth, PCI cards are distributed across all six buses when they are
integrated at the factory.
