Other tips

  • If it is Internal health led then any internal h/w issue is suspected.
  • If it is external health led then any power supply or power source related issue is suspected.
  • Also check the status of the server & its IML (Integrated Management Logs) in ilo (Integrated Lights Out ) if it is configured. (2nd RJ45 port in rear)
  • Also make sure the cabinet is properly closed.
