Power indicator codes
Condition
CAUTION:
Combining AC and DC PSUs is not supported
and triggers a mismatch.

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 to the PSU.
Blinking green
When hot-plugging a PSU, the PSU indicator blinks green. This
indicates that there is a PSU mismatch about efficiency, feature set,
health status, or supported voltage.
CAUTION:
If two PSUs are installed, both the PSUs must
have the same type of label; for example, Extended Power
Performance (EPP) label. Mixing PSUs from previous
generations of PowerEdge servers is not supported, even
if the PSUs have the same power rating. This results in a
PSU mismatch condition, or failure to turn on the system.
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
conversely, 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.
