摘要： The system of the invention includes a board 2 mounted with a plurality of electronic components 1 and a controller 3, which has a faulty component detecting function and a hot swap function. Each of the electronic components 1 is mounted on the board 2 with electronic lock means 4A and 4B and also pressing means 5 and the board 2 is further mounted with a nonvolatile memory 6 in which a board-side unlock code is stored, which code is transmitted by the controller 3 to the electronic lock means 4A and 4B. The electronic lock means 4A and 4B are provided with a function to unlock a component if correspondence is detected between a board-side unlock code and a lock means-side unlock code.
