Pattern
Description
A Green A valid power source is connected to the PSU and the PSU is
operational.
B Flashing green When the firmware of the PSU 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. See Dell
Lifecycle Controller User’s Guide at Dell.com/idracmanuals.
C Flashes 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. Replace the mismatch PSU with a PSU of matching
capacity.
CAUTION: For AC PSUs, use only PSUs with the Extended
Power Performance (EPP) label on the back. Mixing PSUs from
previous generations of PowerEdge servers can result in a PSU
mismatch condition or failure to power on.
D Flashing amber Indicates a problem with the PSU.
