Fault
RED
OFF
The Fault LED tracks the state of the fault relay. (The fault relay signals appear on pins of the
GPIO connector.)
Note: The RED state does not necessarily indicate a problem, but that audio is not actively
being processed and passed. This state occurs normally when the unit is rebooting or has not
yet been configured to run a Project. It also occurs when the unit has encountered a problem
and can no longer process and pass audio.
