Indicator codes for redundant power supply unit
Each AC power supply unit (PSU) has an illuminated translucent handle that indicates whether power is present or whether a power fault
has occurred.

Convention Power Indicator
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.
NOTE: Mixing PSUs from previous generations of Dell PowerEdge servers
can result in a PSU mismatch condition or failure to turn the system on.
D Flashing amber Indicates a problem in the PSU.
CAUTION: When correcting a PSU mismatch, replace only the PSU with the
flashing indicator. Swapping the other PSU to make a matched pair can
result in an error condition and unexpected system shutdown. To change
from a High Output configuration to a Low Output configuration or vice
versa, you must turn off the system.
CAUTION: AC PSUs support both 220 V and 110 V input voltages with the
exception of Titanium PSUs, which support only 220 V. When two identical
PSUs receive different input voltages, they can output different wattages,
and trigger a mismatch.
