Ok on a more serious note from my previous post
On Your QRH You will find a section called "OEBPROC". This is where the OEBs are published and explained. As per Airbus philosophy, anytime an ECAM pops-up You must first ensure there are no OEBs applicable to the failure. In case there are, You are required to action the OEB first and, according to the failure, subsequently disregard or complete the ECAM. This will be detailed in the OEB itself again depending on the problem.
Hope that helps.
