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:

Controller Discovery Process for Lightweight Access Points

The lightweight access point supports these controller discovery processes:
•
•
•
Cisco recommends that you configure a DHCP server with Option 43 to provide the controller IP
addresses to your lightweight access points. Cisco switches provide a DHCP server option that is
typically used for this purpose.

Ensure 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:
http://www.cisco.com/cisco/web/psa/default.html
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.
The integrated antenna design of the 1130AG series access point is designed for horizontal surfaces,
(table top and ceiling installations). When mounted to such surfaces, the integrated antennas
produce the best antenna radiation pattern. For advanced features such as voice, location, and rogue
access point detection, ceiling mounting is strongly recommended. However, for smaller areas such
as conference rooms, kiosks, transportation, and hot-spot usage where the customer is concerned
primarily with data coverage and not advanced features, this unit may be wall mounted using the
supplied plastic wall anchors and #8 screws.
DHCP server discovery—Uses DHCP Option 43 to provide controller IP addresses to the
lightweight access points. Cisco switches support a DHCP server option. For additional information,
refer to the "Configuring DHCP Option 43 for Lightweight Access Points" section on page
DNS server discovery—The lightweight access point uses the name
CISCO-LWAPP-CONTROLLER.<local domain> to discover the controller IP addresses from a
DNS server. Where <local domain> is the access point domain name.
Locally stored controller IP addresses—If the lightweight access point was previously associated to
a controller, the IP addresses of the primary, secondary, and tertiary controllers are stored in the
access point non-volitile memory. The process of storing controller IP addresses in access points for
later deployment is called priming the lightweight access point. For additional information, refer to
the "Priming Lightweight Access Points Prior to Deployment" section on page
You can also manually configure controller information using CLI commands on new
(out-of-the-box) access points that are not connected to a controller. For additional information refer
to the "Manually Configuring Controller Information Using the Access Point CLI" section on
page 4-8.
