Installing the Antenna

Planning the Antenna Installation

To verify the equipment prior to installation, you may need to proceed with the guidelines described in the RoamAbout Access Point User’s Guide before performing the procedures in this chapter. The RoamAbout Access Point User’s Guide is shipped with the RoamAbout Access Point, and can be downloaded from the RoamAbout website at: http://www.cabletron.com/wireless

Safety Precautions

Please read this section carefully before starting the installation. All requirements listed below should be satisfied prior to starting installation of your RoamAbout outdoor antennas.

WARNING

Do not climb rooftops in wet or windy conditions, during a thunderstorm, or when the area where the equipment will be installed is covered with ice or snow.

ELECTRICAL HAZARD WARNINGS

1.Antennas and cables are electrical conductors. Do not touch antennas, RoamAbout Lightning Protectors, or antenna cables during a thunderstorm.

2.The location where you install each antenna must be at a safe distance from power lines or telephone lines. The safe distance should be at least twice the height of the antenna mast plus the height of the antenna.

3.The Contact between antenna components and power lines can result in serious personal injury, or possibly death.

4.Do not install antennas or cables where there is any possibility of contact with high-voltage arc-over from power cables or service drops to buildings.

5.During installation or removal, the antenna, supporting mast and/or tower must not be close to any power lines.
