Note
In the LED states descriptions, a moderate fault is a fault in which the first warning threshold for the
component has been passed (for example, overheating). In most cases, the moderate fault self-corrects,
at which time the LED returns to normal state. A “severe fault” is a fault that requires immediate service
action.
