Appendix A Bus Hierarchy

Bus Hierarchy

The following figure is representative of the PCI Bus hierarchies for the

13 Slot PCI to PCI Expansion System. This figure pictorially conveys the

overall PCI bus topology of the system.

13 Slot Topology

In general, we do not know what the actual Bus numbers are. We only

know how they increment starting from the PCI expansion host card.

The key point in the figure of the 13 Slot Topology is that the connecting

cable between the PCI expansion host card and the 13 Slot backplane

is actually a PCI bus itself. This is represented in the Windows Device

Manager as shown below:

All PCI cards installed in the PCI Expansion chassis will appear on

the Third PCI Bus behind the PCI Bus that the PCI host card is

installed on. If you need to know the actual Bus number, right-click

on the Bus and select Properties.
