– Server Based Power Management (SBPM)
– Redundancy Policy: Power Supply Redundancy or No Redundancy
– Max Power Conservation Mode (MPCM).
– Dynamic Power Supply Engagement (DPSE).
– System Input Power Cap is set to value less than or equal to 13300W or (45381 BTU/h) .
• The chassis does not have six 3000W PSUs or all the PSUs do not support EPP , the EPP option is grayed out and not available
for selection.
Extended Power Performance Scenarios - Using RACADM
Scenario 1: Managing EPP feature control (enable/disable) using racadm getconfig/config set commands
• To enable EPP feature on a 3000W AC PSU configuration, use:
racadm config -g cfgChassisPower -o cfgChassisEPPEnable 1
• To disable EPP feature on a 3000W AC PSU configuration, use:
To disable EPP feature on a 3000W AC PSU configuration, use:
• To verify if the EPP feature is enabled on a 3000W AC PSU configuration, use:
racadm getconfig -g cfgChassisPower -o cfgChassisEPPEnable
Scenario 2: Viewing EPP feature status using racadm getpbinfo:
racadm getpbinfo
Extended Power Performance(EPP) Status = Enabled (inactive)
Available Power in EPP Pool = 3167 W (10806 BTU/h)
Used Power in EPP Pool = 0 W (0 BTU/h)
EPP Percent - Available = 100.0
Scenario 3: Viewing EPP feature control operations recorded in CMC logs:
racadm getraclog
Jul 31 14:16:11 CMC-4C2WXF1 Log Cleared
Jul 31 14:15:49 CMC-4C2WXF1 Extended Power Performance is Enabled
Jul 31 14:15:49 CMC-4C2WXF1 Extended Power Performance is Disabled
Scenario 4: Changing Power configuration properties that are incompatible with EPP, when EPP is enabled:
• Enabling Server Based Power Mangement (SBMP) on a 3000W AC PSU
racadm config -g cfgChassisPower -o cfgChassisServerBasedPowerMgmtMode 1
This feature is not supported while Extended Power Performance is enabled.
• Enabling Dynamic Power Supply Engagement on a 3000W AC PSU
racadm config -g cfgChassisPower -o cfgChassisDynamicPSUEngagementEnable 1
This feature is not supported while Extended Power Performance is enabled.
• Changing Power Redundancy Policy from Grid Redundancy Policy to PSU Redundancy Policy on a 3000W AC PSU
racadm config -g cfgChassisPower -o cfgChassisRedundancyPolicy 2
This feature is not supported while Extended Power Performance is enabled.
• Changing Power Redundancy Policy from Grid Redundancy Policy to No Redundancy Policy on a 3000W AC PSU
racadm config -g cfgChassisPower -o cfgChassisRedundancyPolicy 0
This feature is not supported while Extended Power Performance is enabled.
• Changing System Input Power Cap value to less than or equal to 13300 W
racadm config –g cfgChassisPower -o cfgChassisPowerCap 12500
System Input Power Cap cannot be set to less than or equal to 13300W (45381 BTU/h)
while Extended Power Performance is enabled.
• Enabling 110VAC on a 3000W AC PSU
racadm config -g cfgChassisPower -o cfgChassisAllow110VACOperation 1
This feature is not supported on 3000W power supplies.
• Enabling Max Power Conservation Mode on a 3000W AC PSU
