DUPLEX BOARD SYSTEM AND METHOD FOR SWITCHING DUPLEX BOARDS THEREOF |
摘要 |
PURPOSE: A duplex board system and a method for switching duplex boards thereof are provided to instantly switch an active state board to a standby state board when abnormality is generated in the active state board in hardware, and switch the active state board and the standby state board in software. CONSTITUTION: The second duplex board(20) connects with the first duplex board(10) through communication channels(42,43). A cell bus(30) having a multicasting function is a communication bus between the first or second duplex board(10,20) and another board. The first and second duplex boards(10,20) generate signals for switching active and standby states by a state value decided by their hardware abnormal state and state control signals capable of being controlled in software, and a state value of an object board. |
