Convention Power indicator

pattern

Condition

A Green The handle or LED indicator glows green indicating that a valid

power source is connected to the power supply unit and that the

power supply unit is operational.

B Flashing green When hot-adding a power supply unit, power supply unit LED

flashes green. This indicates that the power supply unit is

mismatched with the other power supply unit (in terms of

efficiency, feature set, health status, and supported voltage).

Replace the power supply unit that has the flashing indicator with a

power supply unit that matches the capacity of the other installed

power supply unit.

C Flashing amber Indicates a problem with the power supply unit.

CAUTION: When correcting a power supply unit mismatch,

replace only the power supply unit with the flashing

indicator. Swapping the opposite power supply unit 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 power supply units support both 220 V and

110 V input voltages with the exception of Titanium power

supply units, which support only 220 V. When two identical

power supply units receive different input voltages, they can

output different wattages, and trigger a mismatch.

CAUTION: If two power supply units are used, they must be

of the same type and have the same maximum output power.

CAUTION: Combining AC and DC power supply units is not

supported and triggers a mismatch.

D Not lit Power supply unit is not connected.
