PCIe 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 PCIe 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 Advanced Configurations

When trying to troubleshoot problems with PCIe 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 PCIe
Expansion Systems and PCIe to PCIe Expansion Systems. Whereas,
Daisy-Chain configurations will consist of a PCIe to PCIe Expansion
System, followed by one or more PCIe to PCIe Expansion Systems.

PCIe cards should you attempt to install any 3 Party PCIe cards.
