During flight hardware integration, priority and precedence must be given to completion of the electrical power interface Safe-To-Mate procedures. Priority and precedence for testing flight hardware implies that Safe-To-Mate is the first test procedure during integration. No other electrical integration procedures should commence until Safe-To-Mate procedure is completed. Incorrect power interfaces have caused more flight hardware damage than any other electronic hardware failure mode.
