2. Hardware Functionality

See Chapter 1.2 for an overview of the product's hardware, along with links to chapters offering detailed
explanations.

2.1 Antennas Interfaces

Three RP-SMA female connectors (WIFI1) are available for WiFi antenna connections.
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. The pinout
of the socket is shown in Figure

Table 6: Ethernet Connector Pinout Description of RJ45 Socket
All four ETH0 ports can be used for PoE PSE if the router is equipped with this feature. For more information
about the PoE, see Chapter 2.3; for technical parameters, see Chapter 4.7.
The isolation barrier of the Ethernet ports against the ground is 1500 V.
