The present invention relates to a global management system for a multimodule, multiprocessor machine (PK). The system is characterized in that it comprises an independent module (SM) dedicated to the global management of a plurality of first modules (M1 through Mn), the independent module (SM) being connected to each management tool (BUMP) for each of the first modules (M1 through Mn) by a first specific link supporting a given communication protocol that makes it possible to manage each of the first modules at the startup of the machine, during the running of the machine, and after the machine stops running, the independent module (SM) being connected to each of the first modules via a second link, and the independent module also being globally connected to the multimodule machine (PK) via a physical link of a local area network (LAN) linked to at least two of the first modules (M2 and M3).
