Troubleshoot Hardware Faults
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 Power OK indicator) or
a subsystem not in a fault state (unlit amber Service Action Required indicator).
Slow Blink Rate
For the slow blink rate, the indicator (typically green) repeatedly lights for half a second during
a one second interval (1 Hz) and turns off for half a second. The slow blink rate indicates an
on-going activity. For example, device rebuilding, booting, or in transition from one mode to
another.
