I found the solution:
cooling fan are not broken.
If alarm come on the cooling fan 12 (6/2/12) on IBBU BTS ultrasite, the problem is on the CCUA Q1.
CCUA can be 2 adress: 4085 or 4084.
PSM manager => climatic control => FAN.
the CCUA must see 9 cooling fan with the good Q1 adress.
I don’t know explain but CCUA and BOIA are the same Q1 Bus for the climatic control.
Problem is over.
