Installation Requirements

Antenna Connections

Before you install or replace antennas, make sure the router is:

Powered off

Disconnected from all power sources

Disconnected from the Field Area Network (FAN)

Removed from a pole-top installation

Optimum Performance

Antennas transmit and receive radio signals which 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:

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 surrounding buildings’ construction impacts antenna signal strength. Consider the

following

—Signals penetrate paper and vinyl walls with little change to signal strength.

—Signals penetrate only one or two solid and pre-cast concrete walls without degrading signal strength.

—Signals penetrate three or four concrete and wood block walls without degrading signal strength.

—Signals penetrate five or six walls constructed of drywall or wood without degrading signal strength.

—Signals are likely to reflect off a thick metal wall and not penetrate it at all.

—Signals are likely to reflect off a chain link fence or a wire mesh with spaces of 1 to 1-1/2 in. (2.5 to 3.8 cm). The fence

acts as a harmonic reflector that blocks the signal.

Microwave ovens and 2-GHz cordless phones can cause signal interference because they operate in the same frequency

range as the device to which your antenna is connected.

For instructions on installing or replacing a Cisco Connected Grid module, see the corresponding installation and

configuration guide for each module.

For detailed instructions on opening the door, see the installation guide of your router. Before installing the antenna

according to the Installing the Antenna, you must complete these steps:

—Open the router chassis door.

—Remove any plug or connector that is installed in the antenna port.

—Verify the correct antenna port for installation, based on the antenna model you are installing.

See the installation document for your router regarding the correct antenna port location. Antennas must be installed in the

correct antenna port for ease of installation and optimal performance.

NOTE: Ensure that you are able to access the antenna port from inside the router. If an installed module prevents you from

reaching the antenna port, you might have to remove the module before installing the antenna, then reinstall the module. See

the corresponding module installation and configuration guide for each module.

Safety Warnings

WARNING: Do not work on the system, or connect or disconnect cables, during periods of lightning activity. Statement 1001

WARNING: Do not locate the outdoor antenna near overhead power lines or other electric light or power circuits, or where it can

come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits,

as they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local

codes (for example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada:Canadian Electrical Code, Section 54).

Statement 1052

WARNING: This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of

a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain

that suitable grounding is available. Statement 1024

WARNING: Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

WARNING: To report a gas leak, do not use a telephone in the vicinity of the leak. Statement 1039

WARNING: 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.

WARNING: This product is not intended to be directly connected to the Cable Distribution System. Additional regulatory

compliance and legal requirements may apply for direct connection to the Cable Distribution System. This product may connect

to the Cable Distribution System ONLY through a device that is approved for direct connection. Statement 1078

WARNING: 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.

Safety Precautions

For your safety, and to help you achieve a good installation, please read and follow these safety precautions. They may save

your life!

For your safety, read and follow these safety precautions.

If you are installing an antenna for the first time, for your own safety as well as others, seek professional assistance. Your

Cisco sales representative can explain which mounting method to use for the size and type antenna you are about to install.

Before you install an antenna, contact your Cisco account representative to explain which mounting method to use for the

size and type of antenna that you are about to install.

Find someone to help you—installing an antenna is often a two-person job.

Plan your installation carefully and completely before you begin. Each person involved in an installation should be assigned

to a specific task, and should know what to do and when to do it. One person should be in charge of the operation to issue

instructions and watch for signs of trouble.

Antenna Installation

The antenna installation includes the following procedures:

Tools and Equipment Required

Installing the Antenna

Tools and Equipment Required

In addition to the parts included in the antenna kit described in the section Contents of the Antenna Kit, you must provide the

following tool to install the antenna on the router:

Phillips screwdriver

Open-end wrench

Drill

Marker or pencil

Installing the Antenna

Follow these instructions to install the antenna:

1. Determine where on the ceiling you want to install the antenna.

2. Create the center hole to accommodate the 3/4”-16 threaded center rod on the Volcano antenna.

3. Position the Volcano antenna onto the ceiling. Mark on the ceiling the location of the three holes.

4. Remove the antenna and drill the three holes. Place the screw anchors into the holes.

5. Position the antenna in place. Secure the antenna onto the ceiling with the 3 screws using a Phillips #2 screwdriver.

6. From inside the ceiling space, place, in order, the flat washer and curved spring washer onto the center rod. Secure the

antenna with the mounting nut.
