Don’t be fooled, this is not a “next generation” Ethernet cable or some token ring cable but rather a Cisco Console Cable.

If you ever take a brand new Cisco device out of the box you’ll see that it comes with a blue flat cable that has a DB9 serial connector on one end and a network RJ45 connector on the other.

In order to configure the basics on a Cisco device you must first Console into the device.

So you take a brand new Cisco Router or switch out of the box and the very first thing you must do prior to installing it is to put a basic configuration on it.
