# Managing Topologies

To manage connected topologies from the FlowVision GUI, click **System** > **Topology**.

The topology screen shows all the connected devices. The devices that are online are shown in green and the devices that are offline are shown in red. Hover the mouse pointer over the device icons to get more information, such as, the IP address, RAM, CPU, SSD, and so on.

The following image shows the topology of devices in the FlowVision GUI:

{% hint style="info" %}
If you open the Device Controls window of a device shown in red in the topology screen, you cannot configure the device properties, as the device is not reachable. You have an option to remove the device, if need be. Click the **REMOVE** button to remove the device.
