Fault History and Fault Code Location

Board Replacements

Troubleshooting
Procedures
If a power-on self-test fails, the diagnostic software updates the fault
history. The fault history indicates whether the diagnostics ran
successfully the last time.
After updating the fault history, the tests stop and initiate the
loading of the Communications board software. During the
Communications board boot process, the fault code appears that
identiÞes any board that caused a power-on self-test to fail.
If a power-on self-test fails after you have rebooted the system and
continues to indicate that a board is not functioning properly, you
should replace the failing board. Contact your authorized PictureTel
service provider.
If, after the new board is installed, the test continues to fail, call your
PictureTel service provider.
