1.1 myUTN
Purpose myUTN allows you to access non-network-ready USB devices (e.g. hard disks, printers,
etc.) in the network. The USB devices will be connected to the USB port of the UTN
server.
Note
The 'Dongleservers' (myUTN-80 and myUTN-800) are exclusively designed for the
deployment of USB dongles.
The software tool 'SEH UTN Manager' handles the access of the USB devices. The
software is installed on all clients that are meant to access a USB device in the network.
The SEH UTN Manager shows the availability of all UTN servers in the network and
establishes a connection between the client and the USB port including the connected
USB device.
System
Requirements
myUTN has been designed for the use in TCP/IP-based networks. The SEH UTN Manager
has been designed for the use in the following systems:
• Windows XP or later
• OS X 10.8.x, OS X 10.9.x, OS X 10.10.x, OS X 10.11.2 and later
1
or mac OS 10.12.x and
later

This chapter contains information concerning the device and the docu-
mentation as well as notes about your safety.
You will learn how to benefit from your UTN server and how to operate
the device properly.
1. OS X 10.11.2 and later: limited USB device support
2. macOS X 10.12.x and later: limited USB device support

Note
This document describes the usage in Mac environments. Information about the usage
in other environments can be found in the relevant system-specific User Manual. For fur-
ther information; see: ’Documentation’ 3.
Procedure and
Basic Functions
After the SEH UTN Manager is started, the network will be scanned for connected UTN
servers. The network range to be scanned is freely definable.
All UTN servers found will be shown in the 'network list' together with the connected
USB devices. The required UTN servers will be selected and added to the 'selection list'.
The UTN servers listed in the selection list can then be used by the user. To use a USB
device, the user establishes a connection between the client and the USB port of the UTN
server to which the USB device is connected.
Figure 1: UTN Server in the network
Note
Types and number of the USB devices to be connected can be found in the respective
'Quick Installation Guide'.
1. Currently, UTN servers do not support USB 3.0 devices in Linux. In order to use an USB 3.0 device, connect
a USB 2.0 hub to the UTN server and the USB 3.0 device to the hub.
