초록 ▼

A method and apparatus for rapid interconnection (hot plugging) peripheral device interface circuits to a computer bus is disclosed. The interconnections are completed using three sets of conductors in the sequence: common grounds, power from the bus and data lines. The time period between the interconnections is determined by the relative set back lengths of the conductors from the card edge and allows for stabilization of voltage and establishment of a stable high impedance state for the peripheral device controller circuits before the data lines are interconnected.

대표청구항 ▼

A data processing system comprising a computer having an SCSI bus; a plurality of peripheral device controllers coupled to the computer by the bus, each controller including control logic circuits and a voltage regulator for applying voltage to said logic circuits and having no delay, reset or degating circuits interposed between the logic circuits and the bus, said logic circuits selected from a class of devices having differing electrical characteristics but complying with the requirements of a defined specification for said class; said bus providing both power to and data transfer with the voltage regulator and logic circuits of each controller; and apparatus for the hot plugging of each peripheral device controller to the SCSI computer bus without disrupting data transfers on an active bus and without the use of delay, reset or degating circuits in the controller, comprising: edge connector means attached to the bus for interconnection of the bus with a corresponding receptacle in a respective controller having parallel arrangement of plural conductors, of three different lengths, for establishing predetermined sequential electrical interconnections with the applications of a reasonable insertion force; at least one longest length of conductor being coupled to voltage regulator and logic circuit ground terminals of the respective controller for providing a first electrical interconnection; at least one intermediate length conductor being coupled to a power terminal of the voltage regulator of the respective controller to provide a second electrical interconnection which occurs subsequent to said first interconnection, the relative lengths of the longest length conductor and the intermediate length conductor being chosen so that, with reasonable insertion force, a sufficient time delay is provided between the first and second electrical interconnections to allow for stabilization of voltage transients induced into the bus by the first interconnection; and the shortest length conductors being coupled to the data input/output terminals of the controller circuit to provide a third electrical interconnection which occurs subsequent to said second interconnection, the relative lengths of the intermediate length conductor and the shortest length conductors being chosen such that, with a reasonable insertion force, a sufficient time delay is provided between the second electrical interconnection and the third electrical interconnection to stabilize the voltage output of the controller voltage regulator and establish a high impedance state in the regulator prior to the third electrical connection.
