The WLA622 supports four antenna ports, two for the 11a radio and two for the 11bg
radio. The supported antennas models are:
802.11bg Radio
ANT-1120-OUT
ANT-1360-OUT
802.11a Radio
ANT-5120-OUT
ANT-5360-OUT
ANT-5PNL-OUT (for single antenna only for use on port 3)
External antennas connect to the N-type RF connectors on the wireless bridge either
directly or using coaxial cables.
Ethernet Port
The wireless bridge 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 wireless bridge as well as a data link to the local
network.
The wireless bridge appears as an Ethernet node and performs a bridging function by
moving packets from the wired LAN to the remote end of the wireless bridge link.
Power Injector Module
The WLA622 receives power through the network cable connection using
Power-over-Ethernet (PoE) technology. An outdoor power injector module is available
seperately and provides two RJ45 Ethernet ports, one for connecting to the WLA622
(PoE Output), and the other for connecting to an WLC or a local LAN switch Data
(Input).
The Input port uses an MDI (i.e., internal straight-through) pin configuration. You can
therefore use straight-through twisted-pair cable to connect this port to most network
interconnection devices such as a switch or router that provide MDI-X ports. However,
when connecting the access point to a workstation or other device without MDI-X ports,
you must use crossover twisted-pair cable.
Informational Note:
The power injector module does not support Power over Ethernet
(PoE) based on the IEEE 802.3af standard. The wireless bridge unit must always be
powered on by being connected to the power injector module.
