3 HARDWARE INSTALLATION

Before mounting antennas to set up your wireless bridge links, be sure you have selected appropriate locations for each antenna. Follow the guidance and information in Chapter 2, “Wireless Link Planning.”

Also, before mounting units in their intended locations, you should first perform initial configuration and test the basic operation of the wireless bridge links in a controlled environment over a very short range. (See the section “Testing Basic Link Operation” in this chapter.)

The wireless bridge includes its own bracket kit for mounting the unit to a 1.5 to 2 inch diameter steel pole or tube. The pole-mounting bracket allows the unit to be mounted to part of a radio mast or tower structure. The unit also has a wall-mounting bracket kit that enables it to be fixed to a building wall or roof when using external antennas.

Hardware installation of the wireless bridge involves these steps:

1Mount the unit on a wall, pole, mast, or tower using the mounting bracket.

2Mount external antennas on the same supporting structure as the bridge and connect them to the bridge unit.

3Connect the Ethernet cable and a grounding wire to the unit.

4Connect the power injector to the Ethernet cable, a local LAN switch, and an AC power source.

5Align antennas at both ends of the link.
