Abstract:
     The invention is in use for protecting single board of having outgoing lines. The parts to be protected include following units: protection boards in use for replacing boards to be protected when fault occurs on the board to be protected; spare external interface configured for external interface of single board to be protected; outgoing line for connection between spare external interface and external interface of single board to be protected; fault detection unit in use for detecting operating state of single board to be protected; connection unit in use for connecting single board to be protected with its external interface in normal condition, and for rearrangement between external interface of single board to be protected and spare external interface. Thus, implementation procedure for protecting single board is not restricted by the wiring of backboard.
