Installation Overview
Procedure
Step 1
Ensure that the Cisco Controller Distribution System port is connected to the network. Use the procedure for
the CLI or the GUI interface, as described in the release appropriate Cisco Controller Configuration guide.
Note
a) Ensure that the AP has Layer 3 connectivity to the Cisco Controller Management and AP-Manager
interfaces.
b) Configure the switch to which the AP should be attached. See the release specific
Configuration Guide
c) Set the controller as the primary controller so that new AP always joins to it.
d) Ensure that you have enabled DHCP on the network.
The AP must receive its IP address through DHCP.
Note
e) Ensure that the network is configured not to block the CAPWAP UDP ports.
f) The AP must be able to find the IP address of the controller. This can be accomplished using DHCP,
DNS, or IP subnet broadcast. This guide describes the DHCP method to convey the controller IP address.
For other methods, refer to the product documentation. For more information, see
Option 43, on page
Note
Step 2
Apply power to the AP. For more information, see
page
79.
a) When the AP attempts to connect to the controller, the LED cycles through an off, green, and red sequence,
taking up to five minutes.
Note
b) If the AP shuts down, check the power source.
c) After the AP finds the primary controller, it attempts to download the software image if the AP software
release differs from the controller release version. While this is happening, the status LED blinks blue.
d) If the software image download is successful, the AP reboots.
Step 3
Configure the AP 802.11AX network settings using the controller CLI, controller GUI, or Cisco DNA Center.
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 you intend to deploy it on the wireless network.
Step 5
If the AP does not indicate normal operation, turn it off and repeat the preinstallation configuration.
To use an SFP module, you must insert it into an AP's SFP port before the AP boots, in order to
ensure correct power consumption and PoE derating.
for the release your controller is running on.
The DHCP server assigns an IP address to an 802.11AX Cisco AP only if a default router
(gateway) is configured on the DHCP server (enabling the AP to receive its gateway IP address),
and the gateway ARP is resolved..
86.
The AP requires a Gigabit Ethernet (GbE) link to prevent the Ethernet port from becoming a
bottleneck for traffic because wireless traffic speeds exceed transmit speeds of a 10/100 Ethernet
port.
If the AP remains in this mode for more than five minutes, the AP is unable to find the primary
controller. Check the connection between the AP and the primary controller and ensure they
are on the same subnet.
