PROBLEM TO BE SOLVED: To facilitate maintenance of a multi-node system comprising a plurality of nodes and a plurality of inter-node switches. SOLUTION: A link processing sequencer 110 receives the instruction of link processing start from a diagnostic processor 30 and generates a 'link processing start' particular code, and a selector 611 transmits the code to an XSW via an encoder 612 and a parallel/serial conversion circuit 613. When receiving the 'link processing start' particular code from a serial / parallel conversion circuit 711 via a decoder 712, a link processing sequencer 210 generates a 'link processing start reception' particular code and transmits the code to a node from a selector 714 via an encoder 715 and a parallel / serial conversion circuit 716. When receiving the 'link processing start reception' particular code from a serial / parallel conversion circuit 614 via a decoder 615, the link processing sequencer 110 reaches a link establishing state.
