The router console port is located on the router exterior and is accessible by removing the seal over the
console port. (For details, see the

On many Cisco routers, you can enter
Ctrl-C
to interrupt the router startup process and then delete or
change the admin password, or view or delete the router configuration.
To prevent unauthorized access to the router configurations and passwords, the Ctrl-C command is
disabled on the Cisco CGR 1240 Router while it is booting up and loading the system software.
