Some wireless AP models have built-in, internal antennas; some support external antennas. APs with internal antennas are certified as a complete unit. External antennas are individually certified for maximum transmitting power and determination of available channels in each country in which the AP is deployed. For a list of the external antennas that can be used with each AP model and how to install them, refer to the ExtremeWireless External Antenna Site Preparation and Installation Guide.
Wireless APs with external antenna ports must be configured to associate the external antenna connected to each antenna port. For more information, see Configuring Wireless AP Properties.
