It allows all current Vocality devices to be upgraded via TFTP. If you would prefer to use another TFTP server please contact your local Vocality support representative for advice. 2 Pre-requisites Windows TM 2000/XP/Vista/7/8 PC VNUT installation code, at least version 4.0.

In this example, the software is assumed to be copied to C:\TFTPBoot. You will need to add a new folder to your C: drive, using Windows Explorer, and rename it TFTPBoot. Then copy the software upgrade into the folder called TFTPBoot. 5 Running VNUT When you installed VNUT an icon like this should have appeared on the desktop. When you double click this icon it will start VNUT. If you cannot find the icon then open Windows Explorer, and go to the directory where the VNUT application was installed (default is C:\Program Files\VNUT) and double click on the file named 'VocalityNetworkUpgradeTool.exe'. On starting up, the VNUT TFTP Server finds out the IP address of your PC and asks you to select one to use. If you want the displayed address then choose OK. Page 3 of 10
Figure 6 VNUT choice of IP address Note: VNUT will display the first IP address presented to it by the Windows operating system. If you have both a wireless LAN and a wired LAN connection, Windows will always present the IP address for the wireless LAN, which is not normally what you want. In this case type over the displayed address with the correct address for the wired LAN connection before choosing OK. If the IP address is correct then you will see the message 'Create Socket OK' on the following page. Figure 7 VNUT reporting valid IP address Page 4 of 10

8 Security settings Figure 11 VNUT Options > Settings menu The VNUT TFTP Server software has security settings, which allow you to limit access to the TFTP Server (PC) to TFTP clients (such as Vocality units) with an IP address within a specified range or to specific IP addresses in a list. If security settings are not used, then any TFTP client (such as a Multiplexer or a PC) could put files onto or copy files from the TFTP Server. Note: When VNUT is first installed, the security settings are blank, which will prevent any client from connecting to the server. You must enter at least one option before using VNUT for the first time. To access the security menu, choose Options > Security. Page 8 of 10
