650W to 525W. From that point onwards, the system's performance is dynamically adjusted to maintain power consumption so as to not exceed the user-specified threshold of 525W.

If the power cap value is set to be lower than the minimum recommended threshold, iDRAC may not be able maintain the requested power cap.

You can specify the value in Watts, BTU/hr, or as a percentage (%) of the recommended maximum power limit.

When setting the power cap threshold in BTU/hr, the conversion to Watts is rounded to the nearest integer. When reading the power cap threshold back, the Watts to BTU/hr conversion is again rounded in this manner. As a result, the value written could be nominally different than the value read; for example, a threshold set to 600 BTU/hr will be read back as 601 BTU/hr.

Configuring Power Cap Policy Using Web Interface

To view and configure the power policies:

1.In iDRAC Web interface, go to Overview Server Power/Thermal Power Configuration Power Configuration. The Power Configuration page is displayed.

The Power Configuration page is displayed. The current power policy limit is displayed under the Currently Active Power Cap Policy section.

2.Select Enable under iDRAC Power Cap Policy.

3.Under User-Defined Limits section, enter the maximum power limit in Watts and BTU/hr or the maximum % of recommended system limit.

4.Click Apply to apply the values.

Configuring Power Cap Policy Using RACADM

To view and configure the current power cap values:

Use the following objects with the config subcommand:

cfgServerPowerCapWatts

cfgServerPowerCapBTUhr

cfgServerPowerCapPercent

cfgServerPowerCapEnable

Using the following objects with the set subcommand:

System.Power.Cap.Enable

System.Power.Cap.Watts

System.Power.Cap.Btuhr

System.Power.Cap.Percent

For more information, see the iDRAC8 RACADM Command Line Interface Reference Guide available at dell.com/support/manuals.

Configuring Power Cap Policy Using iDRAC Settings Utility

To view and configure power policies:

1.In iDRAC Settings utility, go to Power Configuration.
