Power Supply Status Indicators

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 green
When hot-adding a power supply, indicates 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.
Flashing amber
Indicates a problem with the power supply
Important

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 an unexpected system shutdown.
To change from a high output configuration to a low output configuration or vice versa, first power down the system.
AC power supplies support both 220 V and 110 V input voltages. When two identical power supplies receive different input voltages, they may output different wattages and trigger a mismatch.
If two power supplies are used, they must be of the same type and have the same maximum output power.
