Convention Power IndicatorPattern DescriptionCAUTION: When correcting a power supply mismatch, replaceonly the power supply with the flashing indicator. Swappingthe other power supply to make a matched pair can result inan error condition and unexpected system shutdown. Tochange from a High Output configuration to a Low Outputconfiguration or vice versa, you must power down the system.CAUTION: AC power supplies support both 220 V and 110 Vinput voltages with the exception of Titanium power supplies,which support only 220 V. When two identical power suppliesreceive different input voltages, they can output differentwattages, and trigger a mismatch.CAUTION: If two power supplies are used, they must be of thesame type and have the same maximum output power.CAUTION: Combining AC and DC power supplies is notsupported and triggers a mismatch.E Not lit Power is not connected.Indicator codes for non-redundant power supplyPress the self-diagnostic button to perform a quick health check on the non-redundant power supply ofthe system.Figure 9.
