Troubleshooting
This chapter answers common troubleshooting questions you may have
when using the NI PXI-8109 embedded computer.
What if the NI PXI-8109 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. Does your monitor work with a
different PC? If it hangs, note the last screen output that you saw for
reference when consulting National Instruments 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 user manual 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 this same chassis.
• Clear the CMOS. (Refer to the System CMOS section of Chapter 2,
Installation and Configuration.)
