Cisco Cisco 1900 2900 3900 Series 4-Port Gigabit Ethernet HS-WIC with PoE 安装指南

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 that of 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.

Choose 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.

ATM low profile antennas are assumed to be installed in a protected environment where lightning strikes 
will not occur or will not otherwise damage the equipment. In those installations, lightning arrestors are 
not deemed necessary.

If the antenna is used in an environment where a lightning strike near the antenna is possible, 
consideration should be given to installing suitable lightning protection such as an arrestor or other 
protective means.
