Aruba Networks, Inc., in compliance with governmental requirements, has designed the 220 Series access points
so that only authorized network administrators can change the settings. For more information about access poit
configuration, refer to the ArubaOS Quick Start Guide/Instant Quick Start Guide and ArubaOS User Guide/Instant User
Guide.
Summary of the Setup Process
Successful setup of an AP-220 Series access point consists of five tasks, which must be performed in this order:
1. Verify pre-installation connectivity.
2. Identify the specific installation location for each AP.
3. Install each AP.
4. Verify post-installation connectivity.
5. Configure each AP.
Verifying Pre-Installation Connectivity
Before you install APs in a network environment, make sure that the APs are able to locate and connect to the
controller after power on.
Specifically, you must verify the following conditions:
When connected to the network, each AP is assigned a valid IP address
APs are able to locate the controller
Refer to the ArubaOS Quick Start Guide for instructions on locating and connecting to the controller.
Identifying Specific Installation Locations
You can mount the AP-220 Series access point on a wall or on the ceiling. Use the AP placement map generated
by Aruba's RF Plan software application to determine the proper installation location(s). Each location should be
as close as possible to the center of the intended coverage area and should be free from obstructions or obvious
sources of interference. These RF absorbers/reflectors/interference sources will impact RF propagation and
should have been accounted for during the planning phase and adjusted for in RF plan.

Use of this equipment adjacent to or stacked with other equipment should be avoided because it could result in
improper operation. If such use is necessary, this equipment and the other equipment should be observed to
verify that they are operating normally.
Identifying Known RF Absorbers/Reflectors/Interference Sources
Identifying known RF absorbers, reflectors, and interference sources while in the field during the installation
phase is critical. Make sure that these sources are taken into consideration when you attach an access point to its
fixed location.
RF absorbers include:
Cement/concrete—Old concrete has high levels of water dissipation, which dries out the concrete, allowing
for potential RF propagation. New concrete has high levels of water concentration in the concrete, blocking
RF signals.
Natural Items—Fish tanks, water fountains, ponds, and trees
Brick
RF reflectors include:
Metal Objects—Metal pans between floors, rebar, fire doors, air conditioning/heating ducts, mesh windows,
blinds, chain link fences (depending on aperture size), refrigerators, racks, shelves, and filing cabinets.
Do not place an access point between two air conditioning/heating ducts. Make sure that access points are
placed below ducts to avoid RF disturbances.
RF interference sources include:
Microwave ovens and other 2.4 or 5 GHz objects (such as cordless phones)
