Pattern
Condition
A Green A valid power source is connected to the PSU and the PSU is
operational.
B Flashing green When the PSU firmware is being updated, the PSU handle flashes
green.
CAUTION: Do not disconnect the power cord or unplug the
PSU when updating firmware. If firmware update is
interrupted, the PSUs will not function. You must roll back the
PSU firmware by using Dell Lifecycle Controller. For more
information, see Dell Lifecycle Controller User’s Guide at
Dell.com/idracmanuals.
C Flashing green
and turns off
When hot-adding a PSU, the PSU handle flashes green five times at
4 Hz rate and turns off. This indicates that there is a PSU mismatch
with respect to efficiency, feature set, health status, and supported
voltage.
CAUTION: For AC PSUs, use only PSUs with the Extended
Power Performance (EPP) label on the back.
NOTE: Ensure that both the PSUs are of the same capacity.
