PSU Indicator Codes
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 the firmware of the PSU is being updated, the PSU handle blinks
green
CAUTION:
Do not disconnect the power cord or unplug the PSU when
updating firmware. If firmware update is interrupted, the PSUs do not
function.
When hot-plugging a PSU, the PSU handle blinks green five times at a rate
of 4 Hz and turns off. This indicates a PSU mismatch with respect to
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 the system on.
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
