Patent number: 6535944Abstract: A method of servicing a computer system without interrupting operation of the computer system, by connecting a computer component to a board of the computer system, detecting connection of the computer component to the system board using a control circuit, supplying power to the voltage input of the computer component in response to detecting the connection, and thereafter monitoring the power supplied to the voltage input of the computer component. The method may be used for core computer components such as CPU modules and voltage regulator modules. Power to the voltage input of the computer component is turned off in response to a determination that a current level of the power supplied to the voltage input exceeds a specified level. A fault signal is latched in an active state in response to the determination; the fault signal is reset when the component is removed from the system.Type: GrantFiled: March 30, 1999Date of Patent: March 18, 2003Assignee: International Business Machines CorporationInventors: Girish Chandra Johari, Mark Wayne Mueller, Peter Matthew Thomsen, Lucinda Mae Walter

Patent number: 6493827Abstract: A method and system for monitoring and adapting to configuration changes in a data processing system having a known configuration, while power is applied thereto. In response to a configuration change in the data processing system, values are calculated for multiple system operating factors. An alert is provided to a user if at least one of said calculated values, among the multiple system operating factors, is not within a predetermined range of values for the multiple system operating factors. In addition, the operation of the data processing system is restricted to accommodate for any system operating factors which are not within the predetermined range of values, such that the data processing system is guarded from damage due to an unstable configuration.Type: GrantFiled: March 17, 1999Date of Patent: December 10, 2002Assignee: International Business Machines CorporationInventors: Mark Wayne Mueller, Peter Matthew Thomsen, Wallace Tuten, Lucinda Mae Walter

Patent number: 6449676Abstract: A power subsystem for a computer system allows a voltage regulator module (VRM) to be removably connected to a system board, while limiting disturbances on the voltage rails of the system board. The electrical disturbances are prevented by charging voltage outputs of the DC/DC circuit of the VRM prior to directly connecting the voltage outputs to the voltage rails. To ensure that the voltage outputs are properly charged, a VRM connector may be used in which the voltage output pins are shorter than charge pins which are coupled to respective capacitors and to the voltage outputs of the DC/DC circuit. In this manner, as the connector is mated with a corresponding connector on the system board, the capacitors are first charged via resistive paths connected to the voltage rails, prior to directly connecting the voltage outputs to the voltage rails. The VRMs are thus “hot-pluggable,” enabling a user to upgrade or service the system with no interruption.Type: GrantFiled: March 30, 1999Date of Patent: September 10, 2002Assignee: International Business Machines CorporationInventors: Girish Chandra Johari, Mark Wayne Mueller, Peter Matthew Thomsen, Lucinda Mae Walter

Patent number: 6415346Abstract: A circuit card capable of live insertion into an activated electronic system includes a terminal edge from which an edge connector extends a first length. An input decoupling capacitance resides across the edge connector. A backplane within the activated electronic system receives the circuit card, wherein the backplane includes at least one voltage plane, a backplane receptor, and card guide receptor means. The backplane receptor electrically couples the edge connector to the voltage plane when the edge connector engages the backplane receptor. Card guide means are provided for guiding and connecting the circuit card into the backplane, and include at least one conductive member for engaging the card guide receptor means. The conductive member extends a second length from the terminal edge, wherein the second length is greater than the first length. At least one conductive path electrically couples the conductive member across the input capacitance.Type: GrantFiled: March 18, 1999Date of Patent: July 2, 2002Assignee: International Business Machines CorporationInventors: Mark Wayne Mueller, Peter Matthew Thomsen, Lucinda Mae Walter

Patent number: 6378027Abstract: A method of servicing a processor array of a computer system by quiescing a processor selected for maintenance and removing the selected processor from a processor pool used by the computer's operating system. The selected processor is then powered down while maintaining power to and operation of other processors in the processor array. The selected processor may be identified as being defective, or may have been selected for upgrading. The processor array may include several processor clusters, such that the quiescing, removing and powering down steps apply to all processors in one of the processing clusters. The operating system assigns one of the processors in the processor array to be a service processor, and if the service processor is the processor selected for maintenance, the OS re-assigns the service processor functions to another processor in the processor array.Type: GrantFiled: March 30, 1999Date of Patent: April 23, 2002Assignee: International Business Machines CorporationInventors: Richard Bealkowski, Sudhir Dhawan, Kenneth Claude Hinz, Peter Matthew Thomsen

Patent number: 6262890Abstract: A device for solving the electrical, physical, architectural and thermal challenges associated with designing a computer system is disclosed. A memory controller chipset having two or more chips mounted on opposite sides of a system planar helps balance the thermal profile of the system and achieve the strict spacing requirements of advanced computer processors relative to the memory controller chipset. Although the chips are staggered on opposite sides of the system planar, the adjacent edges of the chips substantially align with one another to minimize their separation.Type: GrantFiled: March 18, 1999Date of Patent: July 17, 2001Assignee: International Business Machines CorporationInventors: Sudhir Dhawan, Mark Wayne Mueller, Peter Matthew Thomsen, Lucinda Mae Walter

Patent number: 6229708Abstract: A mechanism has a subassembly that contains a microprocessor. The mechanism allows the microprocessor to be easily installed through frontal or rear access into a rack drawer and subsequently docked into a receiving assembly. The docking mechanism is multi-axis in that installation of the subassembly occurs along a single axis, but docking of the microprocessor occurs along an axis that is normal to the installation axis. Actuation of the installation mechanism is accomplished with a front-to-rear motion which sequentially provides a power connection to the microprocessor and displaces it in a vertical motion. This vertical motion registers and mates the microprocessor with the assembly. The microprocessor is preloaded in its final latched position to restrain it from shock and vibration events while supporting the assembly in a fixed and stable position.Type: GrantFiled: March 25, 1999Date of Patent: May 8, 2001Assignee: International Business Machines CorporationInventors: John Saunders Corbin, Jr., David Allen Hall, Kenneth Carl Larsen, Mark Wayne Mueller, Peter Matthew Thomsen
