You need to first run below command to set the value to On racadm set BIOS.SysSecurity.AcPwrRcvry On Then you need to run below command to create a job for BIOS to apply the setting racadm jobqueue create BIOS.Setup.1-1 After this you need to reboot the server to apply the job
For the life of me, I cannot find a way to set this R620 server to automatically power on when power is applied. The only setting I can find is to continue from the last power setting meaning that if I shut it down cleanly, it won't come up when power is applied because I shut it down. I certainly don't want to simply power it off causing the OS to crash just to get that last setting but it seems the only way. Does anyone know where the setting is or if there is even one?  
R620 always power on
