Troubleshooting
What if the VXIpc 770/870B 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
PWR
LED should stay lit. The
IDE
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?
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. (Refer to the
section.)
