Config AP:
Console to your AP, and use generic cisco credentials (username: cisco, pass: Cisco)
#capwap ap ip address x.x.x.x n.n.n.n       <= this command gives ip address to your AP.
#capwap ap ip default-gateway g.g.g.g     <= this command gives default-gateway address to your AP.
#capwap ap controller ip address c.c.c.c   <= this command tells your AP which controller should it join to.
#capwap ap primary-base                          <= this command tells your AP which is its primary controller in terms of high-availability settings.

Show AP interface config:
#show capwap ip config                             <= this command shows your AP's ip configurations.

Successfull config should brought you to several reloads of your APs.
You may check on your Controller's "Wireless" tab to see weather your newly add APs are joined or not.
