# Adding a node

##

You can add a node using a specific IP address or by searching an IP address range.

Prerequisites

1. Know the IP address or DNS name of the node.

2. User login credentials for the node.

3. If you are planning to assign a baseline to a node when adding it, add the baseline first.

4. When you add a node, SUM installs the prerequisite inventory components by default. If you do not want the components to be installed, clear the Install Prerequisite components if not already installed check box.

5. If the iLO of the server is configured in one of the high security modes or if `Require Host Authentication` is enabled, iLO Administrator credentials are required.

   NOTE: Use this option only for Windows, Linux, and Unknown node types.

Procedure

1. Adding a single node by IP or DNS name
2. Adding a node by searching a range of addresses
3. Adding nodes by input file
