Configuring the power capping policy

To configure the power capping policy, use the information in this topic.

You can choose to enable or disable the power capping function. If power capping is enabled, a selection can be made to limit the amount of power used by the server. If power capping is disabled, the maximum power used by the server is determined by the Power Redundancy policy. To change the setting, first click Reset. Choose your preferred setting; then, click Apply.

Power capping can be enabled using AC power consumption measurements or DC power consumption measurements. From the drop-down menu, select the type of measurements that will be used to determine the power capping limit. When switching between AC and DC, the number on the slider will change accordingly.

There are two ways to change the power capping value:
  • Method 1: Move the slider mark to the desired wattage to set the overall server power limit.
  • Method 2: Input the value in the input box. The slider mark will automatically move to the corresponding position.

Click Apply after making the configuration changes.

Note
The Power Policies option is not available when the XClarity Controller is in a chassis containing blade or high-density server nodes. The power policy is controlled by the chassis management controller instead of the XClarity Controller.
