Troubleshooting
This chapter answers common troubleshooting questions you may have
when using the NI PXI-8104 embedded computer.
What if the NI PXI-8104 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
Installation and Configuration
.)
•
Recover the hard drive on the controller. (Refer to the
Installation and Configuration
.)
