selecting the final location and be sure to allow for routing the antenna cable as
required.
Do not install the access point in wet or dusty areas without protection. Make sure
the temperature ranges between –20˚ C to 55˚ C (–4˚ F to 131˚ F).
Connecting the
Standard Antenna
The access point is supplied with standard detachable antennas. These should be
attached before the access point is installed.
1 Carefully unpack the standard detachable antennas.
2 Screw an antenna into each of the sockets in the access point housing.
3 Hand-tighten the antennas.
4 Position the antennas so they turn out and away from the access point at a
45-degree angle.
As a rule, the initial orientation of the antennas should be perpendicular to the
floor. After network startup, you may need to adjust the antennas to fine-tune
coverage in your area.
Depending on the coverage required for your site, you may want to replace the
standard detachable antennas with one of the external antennas available for use
with the access point. See “Selecting A Different Antenna” on page 11.
Placing the Access
Point
The access point can be placed on a flat surface such as a table or desktop or it
can be mounted on a wall or to the T-rail grid of an acoustical ceiling. If you
choose a flat surface, select one that is clear of obstructions and provides good
reception. Place the access point and adjust the antenna so that the arms point up
and away from the access point at a 45˚ angle.
