Menu path: Structure tree > Devices

In the Devices area, you can manage end devices registered on the UMS Server. All devices registered on the UMS Server are shown.

The name of a device shown in the structure tree is used for identification in the UMS and does not need to be identical to the name of the device in the network. The name shown in the structure tree does not need to be unique and can be used a number of times.

The unit ID serves as a unique identifier. With IGEL devices, IGEL zero clients, devices converted with the IGEL UDC/OSC, and devices with the IGEL UMA, the unit ID is set to the MAC address of the device.

You can structure the Devices area by creating directories and, possibly, sub-directories. When doing so, you should bear in mind that each device can only be shown once in the structure tree. You can move a device by dragging and dropping it from one directory to another.

As of IGEL OS 10.03.100, the following status displays are offered. In order to make them visible, the Devices send updates option must be enabled (default). To do this, go to UMS Administration > Global Configuration > Device Network Settings > Advanced Device's Status Updates.
