What if the Controller 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 PWROK/FAULT LED should stay lit green. 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 dierent
monitor. Does your monitor work with a dierent 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 soware?
■
Refer to your chassis documentation for additional troubleshooting steps.
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 dierent chassis.
■
Try a similar controller in the same chassis.
■
Clear the CMOS.
■
Recover the hard drive on the controller.
■
Make sure the RAM is properly seated.
