Convention Power indicatorpattern ConditionA Green The handle/LED indicator lights green indicating that a valid powersource is connected to the power supply unit and that the powersupply unit is operational.B Flashing green When hot-adding a power supply unit, power supply unit LEDflashes green. This indicates that the power supply unit ismismatched with the other power supply unit (in terms ofefficiency, feature set, health status, and supported voltage).Replace the power supply unit that has the flashing indicator with apower supply unit that matches the capacity of the other installedpower supply unit.C Flashing amber Indicates a problem with the power supply unit.CAUTION: When correcting a power supply unit mismatch,replace only the power supply unit with the flashingindicator. Swapping the opposite power supply unit to makea matched pair can result in an error condition andunexpected system shutdown. To change from a HighOutput configuration to a Low Output configuration or viceversa, you must power down the system.CAUTION: AC power supplies support both 220 V and 110 Vinput voltages with the exception of Titanium powersupplies, which support only 220 V. When two identicalpower supplies receive different input voltages, they canoutput different wattages, and trigger a mismatch.CAUTION: If two power supplies are used, they must be ofthe same type and have the same maximum output power.CAUTION: Combining AC and DC power supplies is notsupported and triggers a mismatch.D Not lit Power is not connected.Documentation matrixThe documentation matrix provides information on documents that you can refer to for setting up andmanaging your system.To...
