Modelling guidelines

  • Periodical power diagnostics
  • Power good - heartbeat signal
  • Expected power drop/outage - prioritise tasks accordingly, plan power budget, and/or backup data
  • Unexpected partial power drop - alert system and adjust power budget and/or prioritise tasks
  • Unexpected power outage - self sustaining system for detecting consistent power flow resuming and stable reboot
