Power Indicator Condition
Pattern
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.

Power Indicator Codes For Non-Redundant Power Supply

The non-redundant power supply has a status indicator and a self-diagnostic button. The self-diagnostic button is used
to perform a quick health check on the non-redundant power supply of the system.

Diagnostic Indicator Condition
Pattern
Not lit Power is not connected or power supply is faulty.
CAUTION: AC power supplies support both 220 V and 110 V input voltages with the
exception of Titanium power supplies, which support only 220 V. 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.
