How do I change the main power fuse?
The NI VXIpc-882 is not equipped with a user-replaceable fuse. If the
internal fuse blows, contact National Instruments for assistance.
Troubleshooting
What if the NI VXIpc-882 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 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, 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 Hard Drive
Recovery section.)
• Clear the CMOS. (Refer to the Default Software Settings section of
Chapter 3, Configuration and Default Settings .)
