Chassis Resources

Chassis resources are used to query the physical chassis, mainboard, fans, temperature, and power status of the device, as well as to set the fan mode, UID indicator LED, and overall power state.

Plain HTTP requests on this page support HTTP Basic Auth and session tokens. The token is carried in the `X-Xsrf-Token` request header, not in the request body. In the examples, replace `` with `http` or `https` according to the service configuration. The current backend registers only one chassis, with `ChassisId` set to `bmc`. Clients should also query the chassis resource collection first, then obtain the actual path from `Members[].@odata.id`.

1 Chassis Resource Collection

Query the list of chassis resources on the current device.
