Cisco Cisco 2106 Wireless LAN Controller

Each year hundreds of people are killed or injured when attempting to install an antenna. In many of 
these cases, the victim was aware of the danger of electrocution but did not take adequate steps to avoid 
the hazard.

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

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 of antenna you are about to install.

Select your installation site with safety as well as performance in mind. Electric power lines and 
phone lines look alike. For your safety, assume that any overhead line can kill you.

Call your electric power company. Tell them your plans and ask them to come look at your proposed 
installation. This is a small inconvenience considering your life is at stake.

Plan your installation carefully and completely before you begin. Successfully raising a mast or 
tower is largely a matter of coordination. Each person 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.

When installing an antenna, remember:

Do not use a metal ladder.

Do not work on a wet or windy day.

Do dress properly—shoes with rubber soles and heels, rubber gloves, long-sleeved shirt or 
jacket.

If the assembly starts to drop, get away from it and let it fall. Remember that the antenna, mast, 
cable, and metal guy wires are all excellent conductors of electrical current. Even the slightest touch 
of any of these parts to a power line completes an electrical path through the antenna and the 
installer: you!

If any part of an antenna system should come in contact with a power line, do not touch it or try 
to remove it yourself. Call your local power company. They will remove it safely.

If an accident should occur with the power lines, call for qualified emergency help immediately.

Refer to the appropriate quick start guide or hardware installation guide for instructions on installing 
controllers and access points.

To meet regulatory restrictions, all external antenna configurations must be professionally installed.

Personnel installing the controllers and access points must understand wireless techniques and 
grounding methods. Access points with internal antennas can be installed by an experienced IT 
professional.

The controller must be installed by a network administrator or qualified IT professional, and the proper 
country code must be selected. Following installation, access to the controller should be password 
protected by the installer to maintain compliance with regulatory requirements and ensure proper unit 
functionality.
