• Selecting the check box to enable Max Power Conservation Mode (MPCM), displays the following message:
Enabling Max Power Conservation Mode option will force servers into a low power, limited
performance mode and disable server power up. Press OK to continue.
Scenario 3: The EPP option is grayed out and not available for selection, if:
• EPP is disabled with 3000W PSUs, and any of the following power settings is enabled:
• 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.
