Convention Power IndicatorPattern Conditionwith respect to efficiency, feature set, health status, and supportedvoltage. Ensure that both the PSUs are the same.D Flashing amber Indicates a problem with the PSU.CAUTION: When correcting a PSU mismatch, replace only thePSU with the flashing indicator. Swapping the other PSU tomake a matched pair can result in an error condition andunexpected system shutdown. To change from a High Outputconfiguration to a Low Output configuration or vice versa,you must turn off the system.CAUTION: AC PSUs support both 220 V and 110 V inputvoltages with the exception of Titanium PSUs, which supportonly 220 V. When two identical PSUs receive different inputvoltages, they can output different wattages, and trigger amismatch.CAUTION: If two PSUs are used, they must be of the same typeand have the same maximum output power.CAUTION: Combining AC and DC PSUs is not supported andtriggers a mismatch.E 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.Table 10.
