The Lexium MDrive Ethernet TCP/IP Configuration Utility uses TFTP (Trivial File Transfer Protocol) to upgrade the firmware application code for the Ethernet controller.
As TFTP runs as a server for the process, it is essential that UDP port 69 be opened to allow both incoming and outgoing traffic on Windows Firewall for the upgrade process to complete successfully. In the case that your IT department doesn’t allow Windows Firewall setting to be adjusted, or that another, third party firewall is in use, request that UDP Port 69 be unblocked, or, perform the upgrade using PC external to your corporate network.
