# Boot Routeren til Rommon
# Ændre [[Cisco Confreg|Configuration]] fra 0x2102 til 0x2142 fra rommon
# Boot Routeren til IOS
# Slette konfigurationen med det ukendte password
# Ændre [Cisco Confreg|Configuration]] fra 0x2142 til 0x2102 fra rommon
# Reboot Routeren
==Boot Routeren til rommon==
For at boote Routeren til rommon, skal man sende <BREAK> karakteren fra terminalemuleringsprogrammet - for eksempel putty - til Consoleporten, når Routeren tændes.
(Der sendes break fra Putty på min Lenovo bærbare når tasten <Fn> holdes nedes samtidig med at der trykkes gentagne gange på <BREAK> tasten.
