Abstract
A pair of buses connect devices and a processor on a backplane. Each device monitors both buses for a bus reset that is produced by the processor on detecting a fault with the active bus, at which time the processor switches to the inactive bus and produces a bus reset signal on the inactive bus, telling the devices to switch to the inactive active bus. The devices are programmed to respond to the reset signal on either bus to make it the active bus.
