Table 15 Redundant AC PSU status indicator (continued)Convention PowerIndicatorPatternConditionPSU to make a matched pair can result in an errorcondition and unexpected system shutdown. To changefrom a High Output configuration to a Low Outputconfiguration 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, whichsupport only 220 V. When two identical PSUs receivedifferent input voltages, they can output differentwattages, and trigger a mismatch.CAUTION If two PSUs are used, they must be of the sametype and have the same maximum output power.CAUTION Combining AC and DC PSUs is not supportedand triggers a mismatch.E Not lit Power is not connected.Non-redundant power supply unit indicator codesPress the self-diagnostic button to perform a quick health check on the non-redundant powersupply unit (PSU) of the system.Figure 15 Non-redundant AC PSU status indicator and self-diagnostic button1. self-diagnostic button2.
