After reviewing the cRIO II user manual, it appears that our cRIO chassis has detected an error in its software. Basically, the status LED blinking twice identifies this error.

This usually occurs when an attempt to upgrade the software is interrupted. The work around is to "Reinstall software on the chassis. Refer to the Measurement & Automation Explorer Help for information about installing software on the chassis."
Please let me know where to find these instructions to reinstall software for FRC cRIO II in "Measurement & Automation Explorer help". I tried to cross reference cRIO-II help files in MAX but was unsuccessful.
TIA!
