The SNx supports a second, non-routable Ethernet network through a USB-to-Ethernet adapter (ACC-USBETH-0). You must connect the adapter between the SNx’s USB port and a second Ethernet network. This external Ethernet network must be limited to a single subnet and be physically separated from the internal Ethernet network to prevent communication between the two networks.
Important: Do not attempt to configure the External LAN and
External LAN IP Data Link if the USB-to-Ethernet adapter is not plugged in to the
engine. Figure 1 shows the External LAN
property that should remain OFF and Figure 2 shows the External LAN IP
Communication Mode that should remain as None until after the
USB-to-Ethernet adapter is connected.

Important: Use only the USB-to-Ethernet adapter that is tested and qualified for use with the SNE. Other non-qualified adapters do not function in the USB ports of the SNE. See USB ports for more information.Figure 3. USB-to-Ethernet adapter and wiring connections
