Powering On the NI 9146
When you apply power to the NI 9146, the chassis runs a power-on self test (POST).
During the POST, the Power and Status LEDs turn on. The Status LED turns off,
indicating that the POST is complete. If the LEDs do not behave in this way when the
system powers on, refer to the Understanding LED Indications section.
Restarting the NI 9146 Using the Reset Button
Pressing the Reset button restarts the NI 9146. The FPGA continues to run unless you
have selected the
Autoload VI on device reboot
chassis reset option.
To restart the NI 9146 in safe mode, hold the Reset button down for about 5 s, until
the Status LED lights yellow, then release the button. The chassis reboots and the
Status LED starts blinking three times every few seconds. The chassis is now in Safe
Mode. Refer to the MAX help for information about safe mode.
Chassis Startup Options
The following table lists the startup options available for the NI 9146. These options
determine how the chassis behaves when it starts up in various conditions. Use
the RIO Device Setup utility to select startup options. Access the RIO Device Setup

Startup Options Behavior
Do Not Autoload VI Does not load the FPGA bit stream from flash memory.
Autoload VI on device
powerup
Loads the FPGA bit stream from flash memory to the FPGA when
the chassis powers on.
Autoload VI on device
reboot
Loads the FPGA bit stream from flash to the FPGA when you reboot
the chassis either with or without cycling power.
