Off = AC power is not connected.
Green (solid) = A valid AC source is connected to the power supply, and the
power supply is operational.
Green (1 Hz blink) = AC is present, but the power switch on the front panel is off
or in a cold redundant state due to low system power load.
Green (2 Hz blink) = Power supply firmware updating.
Amber (blink) = Power supply is operational, but experiencing a warning event.
Amber (solid) = AC power is lost or a power supply is shut down.
