Powering On the MXI-Express x1 System
1. Power on all of the expansion chassis in any order you choose.
2. Power on the host.
Note There are no requirements on the order that connected expansion chassis are powered
up relative to each other, as long as they are all on before the computer is powered on.
3. Observe the LED status on the NI PCI-8361, NI PCIe-8361/8362,
NI PXI-8360/8364, and NI PXIe-8360/8364 where applicable. A
properly connected and powered up system should display a valid link
and power status on all of these boards once the host PC is powered on.
Refer to the LED Indicators section for more information.
Typical PCI-PCI bridges are used to add PCI devices to a PCI hierarchy in
which all the bridges and devices are contained within a single chassis.
Because of this, BIOSes and operating systems make the assumption that
all PCI devices in the entire hierarchy will be available as soon as code
execution begins at power-up time. This assumption means that all of the
expansion chassis must be turned on before the host PC for the BIOS and
OS to correctly configure a MXI-Express system.
Note In some cases where there is an invalid MXI-Express x1 connection, some boards
may report a valid link while others do not. It is important to observe a valid link status
across all connected MXI-Express x1 boards when the host is powered on to ensure a valid
configuration.
