External Antenna Options
The WLA620 unit does not include an integrated antenna, but provides various external
antenna options for both 5 GHz and 2.4 GHz operation. The WLA620 unit requires the
2.4 GHz 8 dBi omnidirectional external antenna for 2.4 GHz operation. The following
table summarizes the external antenna options:
External antennas connect to the N-type RF connectors on the WLA620 using the
provided coaxial cables.
Ethernet Port
The WLA620 has one 10BASE-T/100BASE-TX 8-pin DIN port that connects to the
power injector module using the included Ethernet cable. The Ethernet port connection
provides power to the WLA620 as well as a data link to the local network.
Power Injector Module
The WLA620 receives power through the network cable connection using
power-over-Ethernet technology. A power injector module is included in the WLA620
package and provides two RJ45 Ethernet ports, one for connecting to the WLA620
(Output), and the other for connecting to a WLC switch or a local LAN switch (Input).

Informational Note:
The power injector module does not support Power over Ethernet
(PoE) based on the IEEE 802.3af standard. The WLA620 must always be powered on by
being connected to the power injector module.
