2. Hardware Functionality

See Chapter 1.3 for the product hardware overwiew. Table
hardware, including the links to the chapters with a detailed description.

2.1 Antennas Interfaces

Three R-SMA connectors WIFI1 are designed for the connection of the WiFi antennas.
Recommended tightening moment for screwing the antenna to the SMA connector is 0.9 Nm.

2.2 Ethernet Interfaces

The RJ45 panel socket is used for four ETH0 (switched) and one ETH1 Ethernet interfaces.
