CAUTION: If two PSUs are used, they must be of the same type and have the same

maximum output power.

CAUTION: Combining AC and DC PSUs is not supported and triggers a mismatch.

Power indicator codes Condition

Green

A valid power source is connected to the PSU and the PSU is operational.

Blinking amber Indicates a problem with the PSU.

Not illuminated Power is not connected.

Blinking green When hot-plugging a PSU, the PSU indicator blinks green. This indicates that there is a PSU mismatch

with respect to efficiency, feature set, health status, or supported voltage.

CAUTION: When correcting a PSU mismatch, replace only the PSU with the blinking

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 turn off the system.

CAUTION: If two PSUs are used, they must be of the same type and have the same

maximum output power.

CAUTION: Combining AC and DC PSUs is not supported and triggers a mismatch.
