# Connect to Cisco devices

The first question is asked by those who are using Cisco devices for the first time is that how can I connect to Cisco devices. It needs kind of cable which is called ***rollover cable***.

![Rollover cable](https://3594902569-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LA8bJEHYZEGCK8WGuvC%2F-LA9_U_7X3emytITNyNe%2F-LA9aJMLb4PcILu4djW6%2Fimage.png?alt=media\&token=4f39f66c-910b-4617-8dcf-97c90a3493ff)

rollover cable contains RJ-45 and RS-232 and as it is demonstrated in below picture, RJ-45 is connected to switch and on the other hand RS-232 is connected to PC.

{% hint style="info" %}
Today's PCs usually don't have RS-232 port. You have to buy kind of convertor for RS-232 to USB or you can use new rollover cable which is RJ45 to USB.
{% endhint %}

you can use kind of these software in PC to connect to switch through the console port. [Putty](https://www.putty.org/) is a famous software which supports SSH, Telnet, Serial. 

I upload a video in Youtube to become familiar how to[ connect rollover cable to switch and how to connect switch through Putty](https://www.youtube.com/watch?v=3kpy78M0zPU).
