Cisco Aironet Dual-Band MIMO Wall-Mounted Omnidirectional Antenna (AIR-ANT2544V4M-R)
Safety Precautions
CAUTION: Do not locate the 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 (e.g. U.S.: NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54). Statement 280
For your safety, read and follow these safety precautions.
1.
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.
2.
Find someone to help you—installing an antenna is often a two-person job.
3.
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.
4.
Contact your electric power company. Tell them your plans and ask them to come look at your proposed installation.
5.
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.
6.
When installing your antenna, follow these guidelines:
a.
Do not use a metal ladder.
b.
Do not work on a wet or windy day.
c.
Do dress properly—wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved shirt or jacket.
7.
If the assembly starts to drop, move away from it and let it fall. Because 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.
8.
If any part of the 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 to have it removed safely.
9.
If an accident should occur with the power lines, call for qualified emergency help immediately.
Installation Notes
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:
Install the antenna vertically and mount it with the cables pointing towards the ground.
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 can pass through
and still maintain adequate signal strength. Consider the following before choosing the location for your antenna:
—
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.
