Power Indicator 
Pattern
Condition
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.
