as i said before 

the ap didnot appear in the controller and it's has a frimware issue the light of the ap is solid red 

i want the manual frimware update with out the controller

         - These APs don't use a controller ,

i have another AP works as a controller and many AP's that have been connected to that controller

 - That's probably a mesh network ; you still have to use the mentioned procedure for upgrading the particular AP locally ,

Hi

 Try to factory reset the AP first. It is a simple procedure and  may fix the problem.

Go to "Reset to Factory Settings Using an Open Paperclip"
