c.
After the access point finds the Cisco wireless LAN controller, it attempts to download the 
new operating system code if the access point code version differs from the Cisco wireless 
LAN controller code version. While this is happening, the Status LED blinks amber.
d.
If the operating system download is successful, the access point reboots.
Step 3
Configure the access point if required. Use the controller CLI, controller GUI, or Cisco Prime 
Infrastructure to customize the access-point-specific 802.11ac network settings.
Step 4
If the pre-installation configuration is successful, the Status LED is green indicating normal 
operation. Disconnect the access point and mount it at the location at which you intend to 
deploy it on the wireless network.
Step 5
If your access point does not indicate normal operation, turn it off and repeat the 
pre-installation configuration.
Note
When you are installing a Layer 3 access point on a different subnet than the Cisco 
wireless LAN controller, be sure that a DHCP server is reachable from the subnet on 
which you will be installing the access point, and that the subnet has a route back to 
the Cisco wireless LAN controller. Also be sure that the route back to the Cisco 
wireless LAN controller has destination UDP ports 5246 and 5247 open for CAPWAP 
communications. Ensure that the route back to the primary, secondary, and tertiary 
wireless LAN controller allows IP packet fragments. Finally, be sure that if address 
translation is used, that the access point and the Cisco wireless LAN controller have 
a static 1-to-1 NAT to an outside address. (Port Address Translation is not 
supported.)
