Installing External Antennas
You can optionally install external antennas on the AP-4000/4000M/4900M. For information on the AP’s antenna
functionality, see Antennas.
Follow the mounting instructions included with your external antenna, and then connect the antenna cable to the AP, as
follows:
1. Press down near the center of the compartment covering and slide open the external antenna access compartments.
The compartment closer to the LED panel contains the connectors for the 802.11b/g radio, and the other compartment
contains the connectors for the 802.11a radio.
NOTE: AP-4000 models 8670-US2 and 8670-AU do not provide external antenna connectors for 5GHz (802.11a)
operation.
