2. Hardware Functionality

2.2 Antennas

Connect cellular antennas to the router to main (ANT) and secondary (DIV) SMA female connectors on
the front panel. Connect WiFi antenna to the WiFi RP-SMA female connector on the side of the router.
Only run the router with a cellular antenna connected to the main antenna connector, as the energy
from the transmission is effectively reflected by the open end and can damage the equipment.
The DIV cellular antenna is required for the MIMO DL functionality.
Recommended tightening moment for screwing the antenna to the SMA female connectors is 0.9 Nm.

2.3 Ethernet Interfaces

The maximum length of the cables connected to the Ethernet ports is 30 meters to meet the EMC
immunity conditions.
The panel socket of RJ45 is used for Ethernet interface. The pinout of the socket is shown in Figure
and described in Table 6.
