Preinstallation Checks and Installation Guidelines

Before you mount and deploy your access point, we recommend that you perform a site survey (or use the
Site Planning tool) to determine the best location to install your access point.
You should have the following information about your wireless network available:
• Access point locations
• Access point mounting options: Below a suspended ceiling, on a flat horizontal surface, or on top of a
Note
• Access point power options: Use either of the following options to power the AP:
operating system code if the AP code version differs from the Cisco Catalyst 9800 Series Wireless
Controller code version. While this is happening, the Status LED blinks blue.
When you are installing a Layer 3 access point on a subnet that is different from the Cisco 9800
controller, ensure that the following setup is configured:
• A DHCP server is reachable from the subnet on which you plan to install the AP.
• The subnet has a route back to the controller.
• This route has destination UDP ports 5246 and 5247 open for CAPWAP communications.
• The route back to the primary, secondary, and tertiary controller allows IP packet fragments.
• If address translation is used, the access point and the controller have a static 1-to-1 NAT to
an outside address. Port Address Translation is not supported.

You can mount the access point above a suspended ceiling, but you must purchase additional mounting
hardware. For more information, see
