Figure 6. DC Power Supply Status Indicator1. DC power supply status indicatorPowerIndicatorPatternConditionNot lit Power is not connected.Green The handle/LED indicator lights green indicating that a valid power source is connected to the powersupply and that the power supply is operational.FlashingamberIndicates a problem with the power supply.CAUTION: When correcting a power supply mismatch, replace only the power supply with theflashing indicator. Swapping the opposite power supply to make a matched pair can result in anerror condition and unexpected system shutdown. To change from a High Output configuration to aLow 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 identicalpower supplies receive different input voltages, they can output different wattages, and trigger amismatch.CAUTION: If two power supplies are used, they must be of the same type and have the samemaximum output power.CAUTION: Combining AC and DC power supplies is not supported and triggers a mismatch.FlashinggreenWhen hot-adding a power supply, this indicates that the power supply is mismatched with the otherpower supply (in terms of efficiency, feature set, health status, and supported voltage). Replace thepower supply that has the flashing indicator with a power supply that matches the capacity of theother installed power supply.Other Information You May NeedWARNING: See the safety and regulatory information that shipped with your system.
