Power Indicator	Condition
Pattern
Not lit	Power is not connected.
Green	The handle/LED indicator lights green indicating that a valid power source is connected to the
	power supply and that 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.
