LED Color
LED State
Indication
Yellow
OFF
The IC-317x initialized successfully and is ready for use.
2 blinks
(RT only) The device has automatically booted into safe
mode. This occurs when there is no software installed, which
is the out-of-box state, or the device has detected an error in
its software. Reinstall software on the IC-317x.
3 blinks
(RT only) The IC-317x has booted into safe mode.
4 blinks
(RT only) The IC-317x has experienced two consecutive
software exceptions. The IC-317x automatically restarts after
an exception. After the second exception, the IC-317x
remains in the exception state, alerting you to resolve the
problem. Reinstall software on the IC-317x or contact
National Instruments.
Continuous
blink
(RT only) The IC-317x has not booted into NI Linux Real-
Time. The controller either booted into an unsupported
operating system, was interrupted during the boot process, or
detected an unrecoverable software error.
ON
(RT only) The IC-317x is booting up.
(Windows only) An internal drive is being accessed.
Red
Continuous
blink
This indicates a hardware error. An internal power supply has
failed. Check front-panel I/O connections for shorts. Remove
any shorts and cycle power to the IC-317x. If the problem
persists, contact National Instruments.
