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 flashes green. 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 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 flashing 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 configuration to a Low Output

configuration or vice versa, you must turn off 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 different input voltages, they can output

different wattages, and trigger a mismatch.

CAUTION: If two PSU are used, they must be of the same type and

have the same maximum output power.

CAUTION: Combining AC and DC PSU is not supported and triggers a

mismatch.

D Not lit Power is not connected.

Locating your system Service Tag

Your system is identified by a unique Express Service Code and Service Tag number. The Express Service Code and Service Tag

are found on the front of the system by pulling out the information tag. Alternatively, the information may be on a sticker on the
