A method and system for providing the ability to add or remove components of a data processing system without powering the system down ("Hot-plug"). The system includes an arbiter, residing within a Host Bridge, Control & Power logic, and a plurality of in-line switch modules coupled to a bus. Each of the in-line switch modules provide isolation for load(s) connected thereto. The Host Bridge in combination with the Control & Power Logic implement the Hot-plug operations such as ramping up and down of the power to a selected slot, and activating the appropriate in-line switches for communication from/to a load (target/controlling master).

[ What is claimed is:] [1.] An apparatus for removing components of a data processing system without discontinuing power thereto, the apparatus comprising:a primary bus;a plurality of secondary buses each having a slot capable of receiving an electronic device;selective means for selectively establishing a physical connection from the primary bus to one of the secondary buses, and for removing the connection, the selective means including:a host bridge having an arbiter for receiving requests for control of the primary bus, and for selecting one of the requests as a master for the control;a plurality of switches each for establishing the physical connection from the primary bus to one of the secondary buses, and for removing the connection;removing means for allowing each one of the devices to be removed without discontinuing power to the data processing system, the removing means including:means for detecting when a device resides within one of the slots; andmeans for detecting when an operator desires to remove one of the devices.
