Hey everyone. I recently bought a couple of routers to work towards some certifcations however one of the routers already has a username and password configured on it. I am unable to reach the previous owner. The router is a Cisco 4000. I know it’s old school however for a beginner like me it will serve it’s purpose. I have serched throughout Cisco however the information is overwhelming. I don’t want to accidently erase the OS and I am really new to this technology. Whenever I boot it up it goes right the the username and password prompt. Any suggestions?
