Steady On
For the steady on state, an indicator is continually on (lit) and does not blink. This indicates a
continuing condition, for example, an operational state (green) or a Service Action Required
fault state (amber).
Steady Off
For the steady off state, an indicator is continually off (not lit) and does not blink. This indicates
that a system is not operational, for example, no AC power (unlit green system OK indicator) or
a subsystem not in a fault state (unlit amber Service Action Required indicator).
