Obviously, you will need to keep an eye on your system performance 
and make any adjustments that may be required, either to PCI card 
location or to Expansion System configuration, to obtain maximum 
performance. 
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-On Sequence for Advanced Configurations 
As previously stated in 
, 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 Advanced Configurations 
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 only of a PCI to PCI Expansion 
System, or 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 3
rd
 Party PCI cards should you attempt to 
install any 3
rd
 Party PCI cards. 
Problems with 3
rd
 Party cards might only be traceable once you have 
identified the expansion system containing the problem card. 
Remember, it may be necessary to identify the PCI Slot that the Host 
Interface Card is in before you can properly identify the correct 
expansion chassis and ultimately the card. Obviously, this is only an 
issue if you have multiples of the same type of card installed.
