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 ArubaOS 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: z When connected to the network, each AP is assigned a valid IP address z APs are able to locate the controller Refer to the ArubaOS Quick Start Guide for instructions on locating and connecting to the controller. 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: z 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. z Natural Items: Fish tanks, water fountains, ponds, and trees z Brick RF reflectors include: z 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 z 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: z Microwave ovens and other 2.4 or 5 GHz objects (such as cordless phones) z Lunch rooms and call centers with cordless headsets Dell PowerConnect W-AP120 Series AP | Installation Guide 3
