# Adding a single node by IP or DNS name

Procedure

1. From the Nodes screen, click +Add Node.
2. Select Add a single node or known range of nodes from the Selection operation drop-down list.
3. Enter the IP address, DNS name, range of IP addresses, or multiple addresses separated by commas. For example, entering 10.0.1.1–10.0.1.20 adds 20 nodes. 10.0.1.1, 10.0.1.2, 10.0.1.7 adds three nodes. If the nodes use the same credentials, SUM adds the nodes.
   NOTE:

   - The supported DNS character set is ASCII only—A-Z, a-z, underscore, dot, and 0-9 with hyphen.

     You can add a maximum of 50 nodes.

   - If you are adding a VC node, use the IP address of the primary Enet module. All VC modules installed, including FC modules, are updated through the primary Enet module.

4. Enter a description for the node.
5. In the Node type field, select the node type. If you do not know the node type, select Unknown. During the inventory process, SUM determines the node type.

   Some nodes allow SUM to discover and add associated nodes automatically.

   NOTE:

   Selecting the correct node type might help SUM complete adding the node faster.

6. Optional: To skip the installation of the prerequisite inventory components, clear the Install Prerequisite components if not already installed check box.
   IMPORTANT:

   Performing this action may result in scenarios where SUM may not perform a complete inventory. Two sessions may be required to complete the update in such a case.

7. Optional: Select the baseline, additional package, or both to apply to this node.
8. Optional: Select a group from the list.
9. Select one of the following:

   - Use current credentials (requires existing trust relationship with the node): This option is for Windows nodes only.

   - Enter administrator credentials: Enter the username and password for a user with administrator privileges on the node. If Windows users have administrator privileges, use `domain\username`.

10. Linux nodes allow you to use sudo credentials to deploy updates without logging in to the node with root credentials. To use sudo commands, you have to install sudo capabilities on the node.
    NOTE:

    Super user and sudo are not available for all nodes.

    If you want to use an account that lacks direct root privileges, in the Access Level field, select one of the following:

    - Click Use sudo with credentials entered above if you want to use sudo credentials.

    - Click Enter super user credentials to update components if you want to enter super user credentials.

    NOTE:

    If you are using super user credentials, enter normal user credentials in the Credentials field, and then add super user credentials in the Access Level field. SUM first logs in using the normal user credentials, and then uses the super user credentials to log in to the super user account.

11. If the iLO of the server is configured in one of the High Security modes or if `Require Host Authentication` is enabled, enter the iLO Administrator credentials in the provided iLO Credentials section.
12. Click Add.

    In the Added Nodes section, SUM displays the nodes you selected.
