Table 84. AC PSU status indicator codes (continued)Power indicator codes Conditioncondition and an unexpected system shutdown. Tochange from a high output configuration to a lowoutput configuration or vice versa, you must poweroff the system.CAUTION: AC PSUs support both 240 V and 120 Vinput voltages with the exception of Titanium PSUs,which support only 240 V. When two identical PSUsreceive different input voltages, they can outputdifferent wattages, and trigger a mismatch.Table 85. DC PSU status indicator codesPower indicator codes ConditionGreen Indicates that a valid power source is connected to the PSU,and the PSU is operational.Blinking amber Indicates an issue with the PSU.Not powered on Indicates that the power is not connected to the PSU.Blinking green When hot-plugging a PSU, it blinks green five times at a rateof 4 Hz and powers off. This indicates a PSU mismatch due toefficiency, feature set, health status, or supported voltage.CAUTION: If two PSUs are installed, both the PSUsmust have the same type of label; for example,Extended Power Performance (EPP) label. MixingPSUs from previous generations of PowerEdgeservers is not supported, even if the PSUs have thesame power rating. This results in a PSU mismatchcondition, or failure to power on the system.CAUTION: If two PSUs are used, they must be ofthe same type and have the same maximum outputpower.CAUTION: When correcting a PSU mismatch, replacethe PSU with the blinking indicator. Swapping thePSU to make a matched pair can result in an errorcondition and an unexpected system shutdown. Tochange from a High Output configuration to a LowOutput configuration or conversely, you must poweroff the system.CAUTION: Combining AC and DC PSUs is notsupported.System diagnostics and indicator codes 215
