Appendix A Multiple Expansion System Configurations

8.1
Fan-Out
For reasons described above, we recommend using a fan-out configuration when you need to add successive PCIe expansion systems to the
host computer. This addition to the PCI / PCIe bus hierarchy is at the "peer" level of other existing expansion buses, since these buses will be at
the same hierarchical level within the system configuration.
The Fan-Out configuration is the recommended solution. It typically provides optimum performance on most systems because there are fewer
PCI Bridges between the host computer CPU and the PCIe cards.
For clarification, it is necessary to understand that the amount of latency caused by any PCI Bridge (even those built into a 3
rd
Party PCIe card or the computer motherboard itself) is negligible (“nanoseconds”) and will not produce any visible effect on
most systems. It is only mentioned here because on a few rare configurations, which use some unique PCIe cards with special
software drivers, the total number of PCI buses that the data must pass through COULD make a difference.
Set up
1.
Set the Interface card to “Host” mode. Check the SW4 switch. Move the switch to “OFF-Host” position.
2.
Install the Interface card in the computer, use available PCIe slot, preferably use x16 @ x8 lane.
3.
Connect OSS cables.
4.
Connect power cords. Turn power supply with to “ON” position
5.
Power UP the computer
6.
All expansion units should power up automatically.
