5. Configure each AP.
Note: Dell, in compliance with governmental requirements, has designed the AP-120 series access points so that only authorized
network administrators can change the settings. For more information about AP configuration, refer to the ArubaOS Quick Start
Guide and Aruba OS User Guide.
Caution: Access points are radio transmission devices and as such are subject to governmental regulation. Network
administrators responsible for the configuration and operation of access points must comply with local broadcast regulations.
Specifically, access points must use channel assignments appropriate to the location in which the access point will be used.
Verifying Pre-Installation Connectivity
Before you install APs in a network environment, make sure that the APs will be able to locate and connect to the
controller when powered 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-120 series access point on a wall or on the ceiling. Use the AP placement map generated
by Dell'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.
Unidentified 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 AP 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 within 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 AP between two air conditioning/heating ducts. Make sure that APs 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)
Lunch rooms and call centers with cordless headsets
