Restoring to Factory Defaults

If you need to restore the S4810-ON or N1108EP-ON factory defaults, reboot the system to ONIE Rescue using the run onie-rescue

or run onie-diag commands. If it is not possible to do this with the operating system you installed, reboot the system and hit any key

to stop autoboot.

CAUTION: Restoring factory defaults erases any installed operating system and requires a long time to erase storage.

1 To restore the S4810–ON or N1108EP-ON factory defaults, run one of the following commands:

U-boot mode

run onie_rescue OR run onie_diag

ONIE Rescue bypasses the installed operating system and boots the system into ONIE until you reboot the system.

2 Press ENTER to activate the console.

Example of the Optional ONIE-uninstaller Command

After ONIE Rescue completes, the system resets and boots to the ONIE console.

NOTE: Only use the optional onie-uninstaller command if you want to remove all the network operating software on your

system except for ONIE. This command removes any installed network operating system.

ONIE:/ # onie-uninstaller
