Tools needed: TFTP server, Putty (for Console Access), POE injector, Ethernet cables, Console cable, Serial to USB adapter.

Change you laptop IP address to

Press and hold down the mode button on the AP, then power on the Access Point for about 20 seconds.

in the CLI you should be seeing the following.

Firmware download and installation on the AP would take about 10 mins followed by a reboot of the access point.

By default the AP will send DHCP request for any available server on your network and if successful an IP will be assigned to Ethernet port BVI1.
To statically assign an AP, you can use the following command.
By default the User name is: cisco and password is : Cisco
ap#conf t
ap(config)#int bvi1
ap(config-if)#ip add
ap(config-if)#ip address x.x.x.x x.x.x.x

You can then access the AP through the web portal for additional configuration.
