Resolve all faults first and then check the warnings. Take appropriate action to
resolve the faults, as indicated in the following tables. In cases where there is more
than one possible cause, they are listed from the “most likely” to the “least likely”
cause. Actions are listed in the order that they should be performed; not all actions
may need to be done.

Always use AdminBrowser, if possible, to troubleshoot the system. The Fusion Wide-
band Main Hub and Expansion Hub LEDs are for backup troubleshooting. The RAU
LEDs probably will not provide additional information for troubleshooting.
