Installation Guidelines Chapter 2 Installation Installation Guidelines This section describes things to keep in mind when installing your access point. Sections include: • Basic Guidelines • Installation Above Suspended Ceilings • Coverage Options • Site Surveys Basic Guidelines Because the access point is a radio device, it is susceptible to common causes of interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance: • Install the access point in an area where large steel structures such as shelving units, bookcases, and filing cabinets do not obstruct radio signals to and from the access point. • Install the access point away from microwave ovens. Microwave ovens operate on the same frequency as the access point and can cause signal interference. Installation Above Suspended Ceilings The access point uses a metal enclosure having adequate fire resistance and low smoke-producing characteristics suitable for operation in a building's environmental air space in accordance with Section 300-22(c) of the NEC, such as above suspended ceilings. For mounting instructions refer to Chapter 4, "Mounting Instructions." Caution The 1200 series power injectors are not tested to UL 2043 and should not be placed in a building's environmental air space, such as above suspended ceilings. Note If you plan to mount the access point in environmental air space using a 5-GHz radio, Cisco recommends that you mount the access point horizontally with its antennas pointing down. Doing so will result in the access point complying with regulatory requirements for environmental air space with the 5-GHz radio installed.
