Safety Instructions

  • IMPORTANT SAFETY INSTRUCTIONS

    This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. Use the statement number provided at the end of each warning to locate its translation in the translated safety warnings that accompanied this device. Statement 1071

    SAVE THESE INSTRUCTIONS
  • Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
    Statement 1030

Follow these safety instructions when installing your antenna.

■Plan your installation procedure carefully and completely before you begin.

■If you are installing an antenna for the first time, for your own safety as well as others, seek professional assistance. Consult your dealer, who can explain which mounting method to use for the location where you intend to install the antenna.

■Select your installation site with safety, as well as performance, in mind. Remember that electric power cables and telephone lines look alike. For your safety, assume that any line is an electric power line until determined otherwise.

■Call your local power company or building maintenance organization if you are unsure about cables close to your mounting location.

■When installing your antenna, do not use a metal ladder. Do dress properly: shoes with rubber soles and heels, rubber gloves, and a long sleeved shirt or jacket.

■If an accident or emergency occurs with the power lines, call for qualified emergency help immediately.

Installation Guidelines

As antennas transmit and receive radio signals, they are susceptible to RF obstructions and common sources of interference that can reduce throughput and range of the device to which they are connected. Follow these guidelines to ensure the best possible performance:

■Mount the antenna to utilize its propagation characteristics. This antenna is designed to radiate energy in a somewhat narrow beam from the front of the antenna. It should be aimed into the intended coverage area.

■Keep the antenna away from metal obstructions such as heating and air-conditioning ducts, large ceiling trusses, building superstructures, and major power cabling runs. If necessary, use a rigid conduit to lower the antenna away from these obstructions.

■The density of the materials used in a building’s construction determines the number of walls the signal must pass through and still maintain adequate coverage. Consider the following before choosing the location to install your antenna:

–Signals penetrate paper, vinyl and drywall the easiest. A signal can penetrate five or six walls constructed of drywall or wood.

–Signals are more heavily attenuated passing through concrete and solid-wood walls.

–Signals often reflect off thick metal walls and may not penetrate at all.

■Install the antenna away from microwave ovens and 2 GHz cordless phones. These products can cause signal interference because they operate in the same frequency range as the access point to which your antenna is connected.

Choosing the Mounting Location and Brackets

The antenna is designed for use with the Cisco Aironet AP3702E and AP3702P access points along with the Cisco Hyperlocation module (AIR-RM3010L-x-K9=). The antenna can be mounted only vertically, on a wall, or on a pole. For pole-mounting, the pole should have a minimum diameter of 2 inches and a maximum diameter of 5 inches (50mm - 135mm).

The antenna is designed for both indoor and outdoor deployments. You can deploy it in large halls, warehouses, and atriums having high ceilings.

When mounting the antenna you need to assemble the bracket hardware, mount the antenna using the bracket, and adjust the antenna orientation.

The antenna should be mounted clear of any obstructions to the side or front of the antenna enclosure. Note that this antenna should be aimed into the intended coverage area, and so you should mount the antenna so as to achieve the required mechanical tilt. Mount the antenna as close to the access point so that the access point is within the range of the connecting cables.

Depending on where you are mounting the antenna, there are multiple mounting and bracket assembly options available. See .

Table 1 Choosing the Mounting Options and Bracket Assemblies

Painting the Antenna

Painting the antenna and the bracket does not affect its performance if you use standard exterior-grade, oil-based or latex paint. Do not use metallic or metallic-flake paints, which will degrade antenna performance.

Note Before painting the antenna, cover the pressure-release vent on the rear, lower-left of the antenna with masking tape to prevent clogging (Back view of the antenna).

Cisco recommends Krylon Fusion for Plastic or Rust-Oleum for Plastic (which might require a primer coat). For best results, follow the surface preparation suggestions from the paint manufacturer.
