# Update server hardware capacity settings

To update server hardware capacity settings, perform a `PUT` operation that includes only the `calibratedMaxPower` attribute. View server hardware capacity settings attributes by using a `GET` operation, edit the `calibratedMaxPower` attribute, and then perform a `PUT` operation that includes only the edited `calibratedMaxPower` attribute.

### Prerequisites

- Minimum required session ID privileges: Server administrator

Updating server hardware capacity settings using REST APIs
Select a server hardware URI. `GET /rest/server-hardware` Get the current server hardware capacity using the URI from step 1. `GET `{server hardware URI}`/environmentalConfiguration` Edit the server hardware capacity. The only attribute to send in the response body is `calibratedMaxPower`. Do not send all attributes from the `GET` operation. Update the server hardware capacity. `PUT `{server hardware URI}`/environmentalConfiguration`
