Embodiment Construction

[0014] Now refer to figure 1 , shows a data processing system 20 in which the present invention may be practiced. Data processing system 20 includes processor 22 , keyboard 82 and display 96 . The keyboard 82 is connected to the processor 22 via the cable 28 . Display 96 includes a display screen 30, which may be implemented using a cathode ray tube (CRT), liquid crystal display, electroluminescent screen, or the like. Data processing system 20 also includes pointing device 84, which may be implemented with a trackball, joystick, touch pad or screen, track bar, or, as shown, a mouse. Pointing device 84 may be used to move a pointer or cursor on display screen 30 . Processor 22 is also connected to one or more peripheral devices, such as modem 92 , CD-ROM 78 , network adapter 90 , and floppy disk drive 40 , each of which may be internal or external to a housing or processor 22 . Output components such as printer 100 may also be coupled to processor 22 .

Abstract

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 (202a), residing within a Host Bridge (202), Control and Power Logic (208), and a plurality of in-line switch modules (326, 328) coupled to a bus. Each of the in-line switch modules (326, 328) provides isolation for loads connected thereto. The Host Bridge (202) in combination with the Control and Power Logic (208) 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 to a load (target / controlling master).

Description

technical field [0001] The present invention relates generally to data processing systems, and more particularly to methods and apparatus that allow components to be added or removed to the system without power down. Background technique [0002] Computers have become an integral part of today's society. The demands on, and expectations of, computers have increased to the point that computers must essentially operate on a continuous basis. Unfortunately, over time it may be necessary to update or repair certain parts of your computer. When repairs or updates occur, this typically results in powering down the system. In today's robust environment, having to power down the system is an unacceptable solution. This is especially true for server-type environments. [0003] Therefore, it would be beneficial to have a method and apparatus that would allow the system to be powered off during repairs or upgrades. It would also be beneficial if the system and equipment allowed co...
