This table describes the AC PSU status indicators and what condition is the PSU when the power indicator light is green,
flashing green, flashing amber, and when it is not lit.

pattern
Condition
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.

Flashing green
and turns off
When hot-adding a PSU, the PSU handle flashes green five times at
4 Hz rate and turns off. This indicates a PSU mismatch with respect to
efficiency, feature set, health status, and supported voltage.
NOTE:
Ensure that both the PSUs are of the same capacity.
CAUTION:
For AC PSUs, use only PSUs with the Extended
Power Performance (EPP) label on the back.
NOTE:
Mixing PSUs from previous generations of Dell
PowerEdge servers can result in a PSU mismatch condition or
failure to turn the system on.
D
Flashing amber
Indicates a problem with the PSU.
