POWER LED Indicators

The following table lists the POWER LED indicators.

Table 17. POWER LED Indicators
LED Color LED Pattern Indication
Green Solid The cRIO-903x is powered from the V1 input.
Yellow Solid The cRIO-903x is powered from the V2 input.
— Off The cRIO-903x is powered off.

STATUS LED Indicators

The following table describes the STATUS LED indicators.

Table 18. STATUS LED Indicators
LED Color LED Pattern Indication
Yellow Blinks twice and pauses The cRIO-903x is in safe mode. Software is not installed, which is the factory default state, or software has been improperly installed on the cRIO-903x.

An error can occur when an attempt to upgrade the software is interrupted. Reinstall software on the cRIO-903x. Refer to the Measurement & Automation Explorer (MAX) Help for information about installing software on the cRIO-903x.

Blinks three times and pauses The cRIO-903x is in user-directed safe mode, or the cRIO-903x is in install mode to indicate that software is currently being installed.

This pattern may also indicate that the user has forced the cRIO-903x to boot into safe mode by pressing the reset button for longer than five seconds or by enabling safe mode in MAX. Refer to the Measurement & Automation Explorer (MAX) Help for information about safe mode.

Blinks four times and pauses The cRIO-903x is in safe mode. The software has crashed twice without rebooting or cycling power between crashes.
Continuously blinks The cRIO-903x has not booted into NI Linux Real-Time. The cRIO-903x either booted into an unsupported operating system, was interrupted during the boot process, or detected an unrecoverable software error.
On momentarily The cRIO-903x is booting. No action required.
Red Continuously blinks This indicates a hardware error. An internal power supply has failed. Check front-panel I/O and C Series module connections for shorts. Remove any shorts and cycle power the cRIO-903x. If the problem persists, contact NI.
— Off The cRIO-903x is in run mode. Software is installed and the operating system is running.

User LEDs

You can define the USER1 and USER FPGA1 LEDs to meet the needs of your application. The following table lists the USER1 and USER FPGA1 LED indicators.

Table 19. User LEDs
LED LED Color Description
USER1 Green/Yellow Use LabVIEW Real-Time to define the USER1 LED with the RT LEDs VI. For more information about the RT LEDs VI, refer to the LabVIEW Help.
USER FPGA1 Green/Yellow Use the LabVIEW FPGA Module and NI CompactRIO and Drivers software to define the USER FPGA1 LED. Use the USER FPGA1 LED to help debug your application or retrieve application status. Refer to the LabVIEW Help for information about programming this LED.

Ethernet LED Indicators

The following table lists the Ethernet LED indicators.

LED LED Color LED Pattern Indication
ACT/LINK — Off LAN link not established
Green Solid LAN link established
Flashing Activity on LAN
10/100/1000 Yellow Solid 1,000 Mb/s data rate selected
Green Solid 100 Mb/s data rate selected
— Off 10 Mb/s data rate selected

SD LED Indicators

(cRIO-9030/9031/9033/9034/9035/9036/9038/9039) The cRIO-903x has two LEDs that indicate the SD card drive mount status and activity. The following table lists SD LED indicators.

Table 21. SD LED Indicators
LED LED Color LED Pattern Indication
SD ACT Yellow Off There is no I/O activity on the SD card in the slot.
Flashing The cRIO-903x is performing I/O on the SD card in the slot. Do not remove the SD card while this LED is flashing.
SD IN USE Green Off There is no SD card present in the slot or the cRIO-903x has unmounted the SD card from the operating system. It is safe to remove the SD card from the slot.
Solid The SD card in the slot is mounted in the operating system. Do not remove the SD card while this LED is lit.

WLAN Status LED Indicators

(cRIO-9032/9037) The following table describes the WLAN Status LED indicators.

Table 22. WLAN Status LED Indicators
LED Color LED Pattern Indication
Green Continuously blinks The cRIO-903x is attempting to connect to an existing wireless network.
Solid The cRIO-903x is connected to an existing wireless network.
Yellow Solid The cRIO-903x is operating as a wireless access point.
— Off The cRIO-903x wireless radio is disabled.
