the PXIe-8822/42/62 embedded controller.
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 and cable/adapter. Does your monitor work with a dierent PC? If it
hangs, note the last screen output that you saw for reference when consulting
NI 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.
