This table describes the DC PSU status indicators and the condition of the PSU when
the power indicator light is green, blinking green, blinking amber, and when it is not lit.
Table 43 DC PSU status indicator codes
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 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 VxFlex Ready Node 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.
