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 connected NI 9157/9159 chassis are powered down is not important.
Configuring DIP Switches
Figure 13. DIP Switches
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 described in the
Chassis Powerup
Options section. After startup you can download to the FPGA from
software regardless of switch position.
USER FPGA Switches
You can define the USER FPGA switches for your application. Use the
LabVIEW FPGA Module and NI-RIO software to define the USER FPGA
switches to meet the needs of your application. Refer to
LabVIEW Help for
information about programming these switches.
