Connecting Your Computer to CSN

In order to connect a computer to CSN only a few settings have to be made. All required network parameters will be obtained automatically via DHCP in CSN. Manually setting the parameters mentioned in the confirmation e-mail is not necessary!

In the following, we will describe how to establish a connection to CSN and which settings have to be made in the different operating systems to enable the automatic obtaining of the network parameters via DHCP.

In any case, the registration with CSN and the activation of your port is a prerequisite for establishing a connection.

In every room there is a network outlet for connecting so-called twisted pair cables (TP cables) with RJ45 plugs. These cables are commonly referred to as patch cables. There are two jacks per outlet in most of the dormitories. In order to connect your network card with any one of these jacks you need such a shielded patch cable of category 5 (Cat5) or higher. In the below image you can see an example of a patch cable.

After the physical connection has now been established, you can go on with the configuration of your operating system. Please observe the following information.

A manual configuration of the network parameters is not needed and will not work because of security measures in our network devices. Therefore, all network parameters have to be obtained automatically (DHCP). The parameters mentioned in the confirmation e-mail are for your information only!
