If you want to change the mode to redundancy mode, youmust use IMM2 web interface to set and change the power supply Power Policyand System Power Configurations options settings. You can set and change thepolicies and configurations using the IMM2 web interface, CIM, or the AdvancedSettings Utility. You cannot set or change the Power Policy or System PowerConfigurations options setting using the UEFI Setup utilityIf you do not adhere to the following information, it can cause errors or cause theserver not to boot up (start).v The server supports the following power supply redundancy modes:– Non-Redundant– Fully Redundant– Redundant with Throttlev You must use IMM2 to set and change the Power Policy and System PowerConfigurations.v You cannot use UEFI to change Power Policy and System Power Configurations.v The power configurations and policies can be changed using IMM2 webinterface, CIM, or Advanced Settings Utility (ASU).v Five N+N configurations are supported for 1+1 and 2+2 (as listed in the Systempower configuration screen on IMM2 web interface).v For redundancy, the input feeds must be wired with separate feeds to powersupplies 1 and 3, and power supplies 2 and 4 (this is critical for mixed wattage).v The server will not boot if enough power is not available for the selected policysetting. This can occur if you select 2+2 1400W for the policy setting and one ofthe power supplies is 110 V ac.v The server will not boot when you mix (900W and 1400W) power supplywattage if the power supply slots are not balanced such as 1 and 3, and 2 and 4.v 1400W power supply is 1400W at high line (200 V ac), and only 900W at lowline (100 V ac).v 900W power supply is 900W at both high line and low line.v For 900W ac and 750W dc, a mechanical spacer must be installed in the baywith the power supply.v Suggested power supply installation order is bay 2, 3, 1, then 4.v Power maximizer runs during system boot to verify that the available powermeets the system load requirements.v 750W dc power supply is only supported in a four power supply configuration.Chapter 3.
