AC loss recovery

Setting not accessible from IDRAC. Need to use IDRAC console, reboot machine and enter to setup (F2). In setup it is possible to setup:

  • AC Power Recovery: On (when it is Last system remains off after gracefull shutdown)
  • AC Power Recovery Delay: random - to prevent huge peak consumption when power is restored

Other possibilities - use Linux software to modify BIOS settings:
