Power Indicators are used on each component to indicate the status of the
power distribution network within that component. A single indicator is
utilized to indicate the various power conditions of the component by
utilizing the different indicator states to differentiate the different power
conditions.
Activity LEDs are implemented on various components to provide an
indication of the level of utilization of a component. The LED state is
internally controlled by the component and will utilize the FLASHING
indicator state as internally defined by the component to manage the state
of the indicator.
A blinking Alert/Fault led can be used to identify a component.
