described in the section on chassis powerup options. 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 the
LabVIEW Help
for information about programming these switches.

POWER LED
The POWER LED is lit while the NI 9157/9159 is powered on. This LED is a bi-color LED.
When the chassis is powered from V1, the POWER LED is lit green. When the chassis is
powered from V2, the POWER LED is lit yellow.
USER FPGA LEDs
You can use the bi-color, yellow and green USER FPGA LEDs to help debug your application
or easily retrieve application status. Use the LabVIEW FPGA Module and NI-RIO software to
define the USER FPGA LEDs to meet the needs of your application. Refer to
LabVIEW Help
for information about programming these LEDs.
