Appendix B Need More Slots? 39

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 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 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

Party PCI cards should you attempt to

install any 3

Party PCI cards.

Problems with 3

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.
