Troubleshooting
This section answers common troubleshooting questions you may have when using the
PXIe-8881 embedded controller.
What if the controller does not boot?
Several problems can cause a controller not to boot. Here are some things to look for and
possible solutions.
Things to Notice:
• Which LEDs come on? The PWROK/FAULT LED should stay lit green. The Drive
LED should blink during boot as the disk is accessed.
• What appears on the display? Does it hang at some particular point (BIOS, Operating
System, and so on)? If nothing appears on the screen, try a different monitor and cable/
adapter. Does your monitor work with a different PC? If it hangs, note the last screen
output that you saw for reference when consulting NI technical support.
• What has changed about the system? Did you recently move the system? Was there
electrical storm activity? Did you recently add a new module, memory chip, or piece of
software?
• Refer to your chassis documentation for additional troubleshooting steps.
Things to Try:
• Make sure the chassis is plugged in to a working power source.
• Check any fuses or circuit breakers in the chassis or other power supply (possibly a UPS).
• Make sure the controller module is firmly seated in the chassis.
• Remove all other modules from the chassis.
• Remove any nonessential cables or devices.
• Try the controller in a different chassis.
• Try a similar controller in the same chassis.
• Reset the CMOS.
• Recover the internal drive on the controller.
• Make sure the RAM is properly seated.
