  1. Make sure UpdaterAtor, Concert and GCE are closed
  2. Ensure that a valid default gateway is set for the network interface you are using
  3. If running NCE on an ETC console, make sure the DHCP server is disabled
  4. Open NCE and enable Network Address Server
  5. Navigate the menu on the unit using the front soft key to the Download Software page and Hold the button for 5 seconds 
  6. The latest software, gwinst.bin in this example, (in c:\etc\nodesbin folder) will start to downloading and installing (6.0.1 is the last version that will allow you to switch to Net2 mode)
