🛠 Configure dual 2.5GbE network on EdgeComp MS-U320

Objectives

This tutorial guides beginners through configuring the network connectivity of the BIOSTAR EdgeComp MS-U320. You will learn to identify the two 2.5GbE Ethernet ports, check their status under Linux (Ubuntu 24.04), and test connectivity. The goal is to master the basic network interface for simple IoT or industrial applications.

Required Equipment

• A BIOSTAR EdgeComp MS-U320 mini PC (pre-installed with Ubuntu 24.04 or Windows 11).
• A Cat5e or Cat6 Ethernet cable.
• A 2.5GbE-capable switch or router (or a PC with a compatible NIC).
• An HDMI or DisplayPort monitor.
• A USB keyboard and mouse.
• 9-24V DC power supply.

Steps

1. Physical Connection: Insert the Ethernet cable into the RJ45 port marked "LAN1" (Intel I226-V controller) on the back of the MS-U320. Connect the other end to your switch. Ensure the port LEDs light up.
2. Boot and Access: Connect the DC power. Press the Power button. Once the system boots, log in to your user session.
3. Identify Interfaces (Linux): Open a terminal. Type the following command to list network interfaces:

ip link show

Identify interfaces named enp1s0 or eth0 (for I226-V) and enp2s0 or eth1 (for I226-LM). Check that the state is state UP.

1. Assign IP Address (Linux): For a quick test, assign a static IP to the active interface:

sudo ip addr add 192.168.1.50/24 dev enp1s0
sudo ip link set enp1s0 up

1. Connectivity Test: From another device on the same network, open a terminal and type:

ping 192.168.1.50

If you receive replies, the link is established.

Verification

To confirm the link speed (2.5GbE), use the ethtool command under Linux:

sudo ethtool enp1s0

Look for the line Speed: 2500Mb/s. Under Windows, open Device Manager, go to "Network adapters", right-click the Intel I226-V adapter > Properties > Advanced, and verify the link is active at 2.5 Gbps. The port LEDs should be lit (green or orange depending on the switch manufacturer).

Going Further

Once basic connectivity is mastered, explore configuring the second port (I226-LM) to create network redundancy or isolate an industrial network. You can also test the M.2 slots to add WiFi or 4G/5G modules, leveraging the MS-U320's flexibility in mobile or wireless environments.
