Condition
A valid power source is connected to the PSU and the PSU is
operational.
When the firmware of the PSU is being updated, the PSU handle
flashes green.
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.
Indicates a problem with the PSU.
