Works exactly as advertised. Was able to connect to a Cisco managed switch and factory reset it and then reconfigure it from scratch. Note: The mere presence of this cable does not allow you to connect to the switch. You need a tool like telnet to connect. Cisco makes these instructions available on its website. Hopefully, if you have a Cisco managed switch, you're already familiar with it, but for those who have never dealt with it, you'll need to do a little research.
