cRIO-9075/9076 Operating Instructions and Specifications
Figure 15. cRIO-9075/9076 LEDs
The POWER LED is lit while the cRIO-9075/9076 is powered on. This
LED indicates that the power supply connected to the chassis is adequate.
The STATUS LED is off during normal operation. The cRIO-9075/9076
indicates specific error conditions by flashing the STATUS LED a certain
number of times every few seconds, as shown in Table 3.
Table 3. Status LED Indications
The chassis has detected an error in its software. This usually occurs
when an attempt to upgrade the software is interrupted. Reinstall
software on the chassis. Refer to the Measurement & Automation
Explorer Help for information about installing software on the chassis.
The chassis is in safe mode. Refer to the Measurement & Automation
Explorer Help for information about safe mode.
The software has crashed twice without rebooting or cycling power
between crashes. This usually occurs when the chassis runs out of
memory. Review your RT VI and check the memory usage. Modify
the VI as necessary to solve the memory usage issue.
The chassis has detected an unrecoverable error. Contact National
Instruments.
You can define the USER1 LED to meet the needs of your application. To
define the LED, use the RT LEDs VI in LabVIEW. For more information
about the RT LEDs VI, refer to the LabVIEW Help.
