Safety Precautions when Installing Antennas
Do not locate the antenna near overhead power lines or other electric light or power circuits, or
Warning
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 (e.g. U.S.:
NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54).

Cisco Aironet 1570 Series Outdoor Access Point Hardware Installation Guide
2-6
Has a previous site survey been conducted?
Do you have a clear Fresnel zone between the access points or radio line of sight?
What is the minimum acceptable data rate within the link?
Do you have the correct antenna (if more than one antenna is being offered?)
Do you have access to both of the mesh site locations?
Do you have the proper permits, if required?
Are you following the proper safety procedures and practices?
Have you configured the access points before you go onsite? It is always easier to resolve
configurations or device problems first.
Do you have the proper tools and equipment to complete your survey.
Ensure that a site survey has been performed.
Ensure that your network infrastructure devices are operational and properly configured.
Ensure that your controllers are connected to switch trunk ports.
Ensure that your switch is configured with untagged access ports for connecting your access points.
Ensure that a DHCP server with Option 43 configured is reachable by your access points, or
manually configure the controller information in the access point (for additional information, refer
to the
"Configuring DHCP Option 43" section on page
Become familiar with the access point installation components.
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.
Select your installation site with safety, as well as performance, in mind. Remember that electric
power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.
Contact your electric power company. Tell them your plans and ask them to come look at your
proposed installation.
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.
