2. Hardware Functionality
2.2 Antennas
Connect cellular antennas to the router to main (ANT) and diversity (DIV) SMA female connectors on the
front panel. If the router is WiFi equipped, connect the WiFi antenna to the WiFi RP-SMA female connector
on the front panel.
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 panel socket of RJ45 is used for Ethernet interface. The pinout of the socket is shown in Figure
and described in Table 5.
