Power Supply LED Indicator
The power supply module provides a single external bi-color LED to indicate the status of the
power supply. When AC is applied to the Power Supply Unit (PSU) and standby voltages are
available, the LED will blink green. The LED will be solid on green to indicate that all the power
outputs are available. The LED will be solid on amber to indicate that the power supply has
failed, shutdown due to over current, shutdown due to over temperature, or is indicating a
predictive failure. Refer to the following table for conditions of the LED.
