  The LHC is an accelerator with unprecedented complexity; in addition, the energy stored in magnets and the beams exceeds other accelerators by one to two orders of magnitude. To avoid a plague of technical problems and ensure a safe machine start-up, the hardware commissioning phase was emphasized: the thorough commissioning of technical systems (vacuum, cryogenics, quench protection, power converters, electrical circuits, AC distribution, ventilation, demineralised water, injection system, beam dumping system, beam instrumentation, etc) is carried-out without beam. Activity started in June 2005 with the commissioning of individual systems, followed by operating a full sector of the machine as a whole. LHC architecture allows the commissioning of each of the eight sectors independently from the others, before the installation of other sectors is complete. Important effort went into the definition of the programme and the organization of the coordination in the field, as well as in the tools to record and analyze test results. This paper presents the experience with this approach, results from the commissioning of the first LHC sectors and gives an outlook for future activities.
