Require a minimum of 802.3at POE to power 3802 series AP’s. (they will turn on but radios will not work if not receiving 25.5W)
Require network connectivity with a DHCP server configured, as the Lightweight access point will send out DHCP request for an IP address (saves doing it manually) can use Tftpd64 as DHCP server and TFTP server.
When trying to convert to Mobility Express Image the Access point must not join and existing WLC in your network
Download Mobility Express image from www.cisco.com. You will need a Cisco account to download this image.
Suggest downloading the lightweight image as well in case you want restore the AP
Connect Console and Ethernet cables into their correct interface ports, Ethernet will also be used to power through the use of a Power injector
Plug Ethernet cable from network switch into data port of POE power injector unit and apply power to POE injector
Below log messages are showing that the Lightweight Access point (LAP) is trying to look for a WLC via DHCP request broadcast packet.
Log on to LAP with default username and password of Cisco.
Check that the LAP has been assigned a IP address from the DHCP server on your network. Identify that an IP address has been assigned to the LAP
Setup your TFTP server, (for this I will using Tftpd64) and browse to the folder that contains the Mobility Express image.
In the Command line of the LAP enter the following to download and change the configuration to Mobility Express.
AP#ap-type mobility-express tftp://<TFTP Server IP>/<path to tar>/file
AP#ap-type mobility-express tftp://10.18.22.34/AIR-AP3800-K9-ME-188.8.131.52.tar
When entered correctly the transfer will start
Once image has completed download the file will write to flash and LAP will reboot
enter “yes” to terminate the auto install.
Enter your required configuration items in the config wizard.
Below is a step by step of the WLC wizard configuration process.
Do a ping -t to show you when the AP comes online with the management IP address you assigned.
open HTTPS://IP address of WLC
and there you go.
