Power Indicator
Pattern
Condition
Not lit Power is not connected.
Green A valid power source is connected to the power supply and the power supply is operational.
Flashing amber Indicates a problem with the power supply.
CAUTION: When correcting a power supply mismatch, replace only the power supply
with the flashing indicator. Swapping the opposite power supply 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 power down
the system.
CAUTION: AC power supplies support both 220 V and 110 V input voltages. When two
identical power supplies receive different input voltages, they can output different
wattages, and trigger a mismatch.
CAUTION: If two power supplies are used, they must be of the same type and have the
same maximum output power.
Flashing green When hot-adding a power supply, this indicates that the power supply is mismatched with the
other power supply (in terms of efficiency, feature set, health status, and supported voltage).
Replace the power supply that has the flashing indicator with a power supply that matches the
capacity of the other installed power supply.
