Pattern
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.
CAUTION: Combining AC and DC power supplies is not supported and triggers a mismatch.
Flashing When hot-adding a power supply, this indicates that the power supply is mismatched with the other
green 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.
