Abstract
A method of configuring a data communications system, by changing a default communications address of a logic component to a first assigned address, and connecting the logic component to a communications bus automatically in response to the address change. The logic component may include a multiplexer having an input connected to a first communications bus, and several outputs, some of the outputs being connected to input/output (I/O) devices, and at least one of the outputs being connected to a second communications bus. The latter output is disabled when the logic component has the default communications address; the logic component is connected to the second communications bus by enabling the output of the multiplexer. The invention is particularly adapted for use with a computer system, wherein a service processor having an I C port is connected to the first communications bus, and the service processor communicates with the logic component using an I C bus protocol to send data across the first communications bus to an input/output expander of the second logic component.
