Figure 9 DC PSU status indicator (continued)

DC PSU status indicator
Table 29 DC PSU status indicator codes
Power indicator codes
Green
Blinking amber
Not illuminated
Blinking green
Condition
A valid power source is connected to the PSU, and the PSU is
operational.
Indicates a problem with the PSU.
Power is not connected to the PSU.
When hot-plugging a PSU, the PSU indicator blinks green. This
indicates that there is a PSU mismatch regarding 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 systems based on 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.
CAUTION
Combining AC and DC PSUs is not supported and
triggers a mismatch.
