Unused Antenna Ports - Cisco 4G-ANTM-OM-CM Manual

Cisco Industrial Routers and Industrial Wireless Access Points Antenna Guide

Unused Antenna Ports

Port plugs must be installed in any unused antenna ports.
The weatherproof caps on the connectors protect the router interior from environmental elements including water, heat, cold,
and dust. They are installed on unused ports before the router is shipped.
When you install a new antenna in a port with an N-connector:

Chassis-mounted antennas—Remove the weather proof cap before installing a chassis-mounted antenna.

External antennas—Remove weatherproof cap, then connect the supported Cisco cable to the connector.
