Antennas Interfaces
SMA connectors
ANT0
,
ANT1
,
ANT2
and
ANT3
are intended to be used for connection
of the cellular antennas to the router. The GNSS antenna can be connected to the
GNSS
SMA connector. Three R-SMA connectors
WIFI1
are designed for the connection of the WiFi
antennas.
Do not run the router without connected cellular antennas as the energy from the trans-
mission is effectively reflected by the open end and can damage the equipment.
Recommended tightening moment for screwing the antenna to the SMA connector is 0.9 Nm.

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
and described in Table

All four ETH0 ports can be used for PoE PSE, if the router is equipped with this feature. For
technical parameters of PoE see Chapter
The isolation barrier of the Ethernet ports against the ground is 1500 V.
