Figure 6. AC PSU status indicator

1.AC PSU status indicator/handle

Convention	Power indicator	Condition
	pattern
A	Green	A valid power source is connected to the PSU and the PSU is
		operational.
B	Flashing green	When the firmware of the PSU is being updated, the PSU handle
		flashes green.
C	Flashing green	When hot-adding a PSU, the PSU handle flashes green five times at
	and turns off	4 Hz rate and turns off. This indicates that there is a PSU mismatch
		with respect to efficiency, feature set, health status, and supported
		voltage. Replace the PSU with a PSU that matches the capacity of
		the other PSU.
		CAUTION: For AC PSUs, use only PSUs with the Extended
		Power Performance (EPP) label on the back. Mixing PSUs from
		previous generations of Dell PowerEdge servers can result in a
		PSU mismatch condition or failure to power on.
D	Flashing amber	Indicates a problem with the PSU.
		CAUTION: When correcting a PSU mismatch, replace only the
		PSU with the flashing indicator. Swapping the PSU 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.
