Solution
The Status LED flashing may indicate different conditions depending on its flash pattern. Refer to your device's user manual for specific details. For a general overview of the LED patterns, originally documented for CompactRIO but applicable to other devices, there is a general summary here.
A continuous flashing Status LED (without pauses) indicates that the device is in an unrecoverable state. Several factors can cause an sbRIO (Single Board RIO) device to enter this condition. Before contacting National Instruments Support, try the following steps:
- Power cycle the device if this has not already been performed.
- Reset the device using the Reset button on your sbRIO. For sbRIO-9651 devices, use the Reset button located on the reference carrier board to which the SOM is attached.
- If the device is able to establish a connection with a host, try to format and reinstall the software on the device as described in the resources listed in the Related Links section.
Sometimes improper power can be a cause of this issue. If you are unable to connect to the host PC:
- Using a multi-meter or other measurement device, verify the DC power to the device is a steady and continuous 3.3V for the sbRIO-9651 or within the specifications outlined in the user manual for your other sbRIO device.
- Verify all pins connecting your SOM to the carrier board are making full contact.
- Try different Ethernet cables to connect to the host to ensure it is not a cabling error.
- Verify if the device is able to enter Safe Mode by following the procedure outlined in the user manual.
If none of the above troubleshooting steps work or the device is simply not able to leave this unknown state at all, please contact National Instruments technical support for advice.
