Troubleshooting
This chapter answers common troubleshooting questions you may have
when using the NI PXI-8108 embedded computer.
What if the NI PXI-8108 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 Power OK LED should stay lit.
The Drive LED should blink during boot as the disk is accessed.
• Was the display installed prior to power-on? 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?
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 an uninterruptible power supply).
• 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.)
• Recover the hard drive on the controller. (Refer to the Hard Drive
Recovery section of Chapter 2, Installation and Configuration.)
