If you need to restore the S6000–ON factory defaults, reboot the system to ONIE Rescue mode.
If it is not possible to do this with the operating system you installed, reboot the system and from Grub and select ONIE: Rescue.
ONIE Rescue bypasses the installed operating system and boots the system into ONIE until you reboot the system. After ONIE Rescue completes, the system resets and boots to the ONIE console.
