Menu path: Navigation 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 navigation 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 navigation tree does not need to be unique and can be used a number of times.

Up to and including Version 5.01.100, the MAC address serves as a unique identifier for a device. From Version 5.02.100, the unit ID serves as a unique identifier. With IGEL devices, IGEL zero clients, devices with the IGEL UDC and devices with the IGEL UMA, the unit ID is assigned 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 navigation tree. You can move a device by dragging and dropping it from one directory to another.

The symbols in the navigation tree show the status of a device:

TC online

The device is online.

The device is offline.

Changes were not yet transferred to the device (possible with all statuses).

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


The device will show the logon screen (if configured).


The device will receive an update.


The UMS has no license for the device.


The device has never been registered.

The UMS monitors the status of the devices by regularly sending UDP packets. In accordance with the preset, this occurs every 3 seconds. You can specify the interval for the online check in the Misc > Settings > Online Check menu. You can also update the status manually.

From Version 5.05.100, UMS also supports the management of devices marked with a cloud symbol via IGEL Cloud Gateway (ICG):


The device connected via IGEL Cloud Gateway is offline.
