We need to disable the AP console access.
We can do this by disabling the AP console in the AP system profile.
(master) #configure t Enter Configuration commands, one per line. End with CNTL/Z (master) (config) #ap system-profile move (master) (AP system profile "move") #no console-enable
After the above configuration, if we try to attach the console cable to the AP console Port, we do not get any output.
