Abstract

PURPOSE:To attain continuation of the business work by using a connection/disconnection control circuit for upper/lower interfaces and cutting off automatically the connection of upper and lower interfaces and connecting them to a back- up device. CONSTITUTION:When an information processor 102 has a recovery unable fault, a control part 302 turns on a fault signal 405. Then a switch control part 401 turns on a switch command transmission signal 406 and at the same time turns switches 403 and 402 to the side 2 from the side 1 and vice versa. When a switch command reception signal 407 is received from another information processor 102, the part 401 turns switches 403 and 402 to the side 2 from the side 1 and vice versa to perform the connection and disconnection between the processor 102 and upper and lower interfaces respectively. Then the processor 102 starts automatically the rise business work when it is changed to a connection mode from a disconnection mode.
