Condition
CAUTION: If two PSUs are used, they must be of the same type and have the
same maximum output power.
CAUTION: Combining AC and DC PSUs is not supported and triggers a
mismatch.
E Not lit Power is not connected.

Convention Power indicator pattern Condition
A Green A valid power source is connected to the PSU and that the PSU is operational.
B Flashing green When hot-adding a PSU, the PSU indicator ashes green. This indicates that there is a
PSU mismatch with respect to eciency, feature set, health status, and supported
voltage. Ensure that both the PSUs are of the same capacity.
C Flashing amber Indicates a problem with the PSU.
CAUTION: When correcting a PSU mismatch, replace only the PSU with the
ashing indicator. Swapping the PSU to make a matched pair can result in an
error condition and unexpected system shutdown. To change from a High
Output conguration to a Low Output conguration or vice versa, you must
turn o the system.
CAUTION: AC PSU support both 220 V and 110 V input voltages with the
exception of Titanium PSU, which support only 220 V. When two identical PSU
receive dierent input voltages, they can output dierent wattages, and
trigger a mismatch.
