PCI Card Conflicts

If you determine that one PCI card is interfering with the operation of another card, first try reorganizing the cards on the motherboard. Moving the cards around can change the order in which the cards are configured by the system during power-on. This will go a long way toward resolving module conflicts.

Power-OnSequenceforAdvanced Configurations

As previously stated in Chapter 2 Hardware Installation, it remains necessary to power up ALL Expansions Systems BEFORE you turn on the computer. This will ensure that your power-on software can read all available PCI buses and properly configure all installed PCI cards.

Obviously, the reverse also remains true for shutting your system down. The computer must be shut off BEFORE you attempt to turn off your Expansion System(s).

Troubleshooting AdvancedConfigurations

When trying to troubleshoot problems with PCI cards in a multiple expansion system configuration, it is vital to correctly determine the nature of the problem. Therefore, the first task is to identify the card or chassis having a problem by using the Windows Device Manager, or Apple System Profiler. Refer to the first part of this Appendix for more information on identifying hierarchical levels in multiple expansion system configurations.

Remember, Fan-Out configurations can consist of both PCIe to PCI Expansion Systems and PCI to PCI Expansion Systems. Whereas, Daisy-Chain configurations will consist of a PCIe to PCI Expansion System, followed by one or more PCI to PCI Expansion Systems. Only after you have all expansion systems working without any 3rd Party PCI cards should you attempt to install any 3rd Party PCI cards.
