Troubleshooting
This chapter answers common troubleshooting questions you may have
when using the NI 8171 series embedded computer.
What if the NI 8171 series 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.
•
What appears on the display? Does it hang at some particular point
(BIOS, Operating System, etc.)? 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 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.
•
Recover the hard drive on the controller. (See the
section in Chapter 4,
