If you want the NI 9157/9159 to autoload and run a VI at powerup, you must also configure
the VI to autoload before you compile it. For more information about autoloading VIs, refer to
the
LabVIEW FPGA Module Help

Checking MXI-Express LINK LEDs for Status
After powering on the chassis and host system, check the MXI-Express LINK LEDs to ensure
that all connected systems are linked and communicating properly. The MXI-Express LINK
LEDs of the NI 9157/9159 indicate the following:
Table 2.
NI 9157/9159 MXI-Express LINK LED Indications
LINK LED Appearance
Meaning
Off
Chassis power is off.
Solid yellow
Link is not established.
Solid green
Link is established.
Blinking yellow
PCI Express clock is incompatible with NI 9157/9159
Note
For information about PCI Express clock compatibility with the
NI 9157/9159, go to
915xclock
.
Powering Down the MXI-Express System
Always power down the host system before powering down any connected NI 9157/9159
chassis. When the host system is powered down, the order in which the NI 9157/9159 chassis
are powered down is not important.
Configuring DIP Switches

USER FPGA3
OFF
All of the DIP switches are in the OFF position when the chassis is shipped from National
Instruments.
NO FPGA APP Switch
Push the NO FPGA APP switch to the ON position to prevent a LabVIEW FPGA application
from loading at startup. The NO FPGA APP switch overrides the chassis powerup options
