This chapter answers common troubleshooting questions you may have 
when using the NI PXI-8104 embedded computer.

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 

 section of Chapter 2, 

.)

•

Recover the hard drive on the controller. (Refer to the 

 section of Chapter 2, 

.)
