Chapter 2 Installing the Access Point
Basic Installation Guidelines
Basic Installation Guidelines
Because the access point is a radio device, it is susceptible to interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance:
•Ensure that a site survey has been performed to determine the optimum placement of access points.
•For lightweight access points, check the latest release notes to ensure that your controller software version supports the access points to be installed. You can find the controller release notes by selecting your controller under Wireless LAN Controllers at this URL:

•Ensure that access points are not mounted closer than 20 cm (7.9 in) from the body of all persons.
•Do not mount the access point within 3 feet of metal obstructions.
•Install the access point away from microwave ovens. Microwave ovens operate on the same frequency as the access point and can cause signal interference.
•Do not mount the access point outside of buildings.
•Do not mount the access points on building perimeter walls unless outside coverage is desired.
Controller Discovery Process for Lightweight Access Points
The lightweight access point supports these controller discovery processes:
•DHCP server
•DNS server
•Locally stored controller IP
You can also manually configure controller information using CLI commands on new
Cisco recommends that you configure a DHCP server with Option 43 to provide the controller IP addresses to your access points. Cisco switches provide a DHCP server option that is typically used for this purpose.
