PCI e Card Conflicts

If you determine that one PCIe 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-On Sequence for Advanced 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 buses and properly configure all installed PCIe 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 PCIe cards in a multiple expansion system configurations, 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.

Problems with 3rd Party PCIe cards might only be traceable once you have identified the expansion system containing the problem card.

Below is a flow chart offering a troubleshooting approach when multiple expansion chasses are involved:
