# Add a node to a Collibra Platform Self-Hosted environment

A node is a physical server that runs one or more services of a Collibra Platform Self-Hosted environment.

## Prerequisites

* The node that you want to add to your infrastructure must be up and running and reachable from the Console that you are using.
* The version of the node must match the version of Collibra Console.

{% hint style="success" %}
To add a node that was previously registered to another Collibra Console, go to the knowledge base on the [Collibra Support Portal](https://support.collibra.com/hc/en-us/articles/4407882587537-How-to-re-add-an-existing-node-to-another-Collibra-Console-for-on-premise-only).
{% endhint %}

## Steps

{% stepper %}
{% step %}
Open Collibra Console with a user profile that has the **SUPER** role.\ <i class="fa-chevrons-right">:chevrons-right:</i> Collibra Console opens with the **Infrastructure** page.

{% hint style="success" %}

* The default address to access Collibra Console is *\<server hostname>:4402*, but you may have set another port during the installation of Collibra Console. Keep in mind that a firewall of your operating system can block the access to Collibra Console.
* The default credentials to sign in to Collibra Console are *Admin* / *admin*. We highly recommend that you [edit](https://productresources.collibra.com/docs/collibra/latest/Default.htm#cshid=DOC1516) the Collibra Console administrator's password after signing in for the first time.
