Preinstallation Checks And Installation Guidelines - Cisco Catalyst 9136I Series Hardware Installation Manual

Installation Overview
• If the AP shuts down, check the power source.
• After the AP finds the Cisco 9800 controller, it attempts to download the new operating system code if
If the operating system download is successful, the AP reboots.
Step 3 (Optional) Configure the AP, if required. Use the controller CLI, GUI, or Cisco DNA Spaces to customize
the access point-specific 802.11ax network settings.
Step 4 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 5 If your AP does not indicate normal operation, turn it off and repeat the preinstallation configuration.

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:
If the AP remains in this mode for more than five minutes, the AP is unable to find the primary

Cisco 9800 controller. Check the connection between the AP and the Cisco 9800 controller
and be sure that they are on the same subnet.
the AP code version differs from the Cisco 9800 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 the following setup is configured:
• A DHCP server is reachable from the subnet on which you will be installing the AP.
• The subnet has a route back to the Cisco 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 Cisco controller have a static 1-to-1 NAT
to an outside address. Port Address Translation is not supported.
