Hello,  We found a solution, the mistake was really stupid.  We call the api with "/redfish/v1/Systems/Members('10413')/Actions/ComputerSystem.Reset", with that the answer is an error 501. It's missing the "https://", so it understanding that as http, so it's failing.  Now everything work, thanks a lot !
Hello,  I'm trying to manage power status of multiples dell devices from our data center.  My device has idrac installed, and when I use the redfish api call it's working perfectly. But to adapt it to all the devices of the company I'm trying to use OpenManage to do it for me.  So OpenManage is configured and working well (/api/DeviceService/Devices) show all my devices. With my ID I can use a second call using a redfish link (find in the documentation).  So this get call work perfectly and show me information of my devices: {my-ip}/redfish/v1/Systems/Members('{id}') The issues is now, in the target part of the response, it describe me to use this POST call :  {my-ip}/redfish/v1/Systems/Members('{id}')/Actions/ComputerSystem.Reset Using as body this information, and as header "Content-Type": "application/json And the response is an error 501. Impossible to do anything. I tried to change my body with "PowerOn" find in the documentation and the issus still stay the same.  Do you have an Idea if I'm using the good endpoints or if something is missing ?  Thanks a lot
