# SUM Nodes screen

Nodes are servers or devices that SUM can independently update. The Nodes screen displays the nodes and associated nodes that you have added to SUM and SUM can manage. The node details that SUM displays varies based on the node type.

The yellow status bar under the node name gives a brief description of the status or action you can perform next on the node. For full details, click the Actions arrow. For example, after you add a node, the status bar might give a link to Inventory the node. Or, after you inventory a node, the status bar will provide a link to review and deploy updates.
