Dell E20S001 owner manual Power Indicator Codes For Non-Redundant Power Supply

Power Indicator	Condition
Pattern
Not lit	Power is not connected.
Green	A valid power source is connected to the power supply and the power supply is operational.
Flashing amber	Indicates a problem with the power supply.
	CAUTION: When correcting a power supply mismatch, replace only the power supply
	with the flashing indicator. Swapping the opposite power supply to make a matched pair
	can result in an error condition and unexpected system shutdown. To change from a High
	Output configuration to a Low Output configuration or vice versa, you must power down
	the system.
	CAUTION: AC power supplies support both 220 V and 110 V input voltages. When two
	identical power supplies receive different input voltages, they can output different
	wattages, and trigger a mismatch.
	CAUTION: If two power supplies are used, they must be of the same type and have the
	same maximum output power.
Flashing green	When hot-adding a power supply, this indicates that the power supply is mismatched with the
	other power supply (in terms of efficiency, feature set, health status, and supported voltage).
	Replace the power supply that has the flashing indicator with a power supply that matches the
	capacity of the other installed power supply.
