Cisco Catalyst IW9167I - Preinstallation Checks and Installation Guidelines

Step 3 If the preinstallation configuration is successful, the Status LED is green, indicating normal operation. Disconnect the
AP and mount it at the location at which you intend to deploy it on the wireless network.
Step 4 If your AP does not indicate normal operation, turn it off and repeat the preinstallation configuration.
When you are installing a Layer 3 access point on a subnet that is different from the Cisco Catalyst 9800
Series Wireless Controller, ensure 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.
Note
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: To a vertical or horizontal wall or a pole
• Access point power options: Use either of the following options to power the AP:
• DC power input
• Cisco-approved power injector
• 802.3at (PoE+), 802.3bt, and Cisco Universal PoE (Cisco UPOE)
• Operating temperature: -40° to +131°F (-40° to +55°C) with solar load and still air.
Extended operating temperature (DC powered): -58° to +149°F (-50° to +65°C) without solar loading,
still air, and cold start limited to -40°C
• Console access using the console port
We recommend that you use a console cable that is one meter or less in length.
The AP may face issues while booting if you use an unterminated console cable
(not plugged into any device or terminal) or a console cable that is more than one
meter in length.
