Condition
A valid power source is connected to the PSU and the PSU is
operational.
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.
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. Ensure that both the PSUs are the same.
NOTE: For AC PSUs, use only PSUs with the Extended Power
Performance (EPP) label on the back. Mixing PSUs from
previous generations of Dell PowerEdge servers can result in a
PSU mismatch condition or failure to turn on.
Indicates a problem in the PSU.
