Automated backplane cable connection identification system and method

Abstract

An automated backplane cable connection system (and method) for manually connecting a cluster of processor modules to other modules or I/O boxes uses a programmed server management control console which identifies connection terminals provided on the processors/I/O boxes and controls LEDs which are associated with the connection terminals, on a one to one basis. The programmed server management console uses diagnostic circuitry and causes LEDs corresponding to connection terminals engaged by a newly made cable connection to initially light up, and enables them to turn off if the newly made cable connection is proper as verified by the diagnostic circuitry. The cluster of processor modules may be connected to a plurality of I/O boxes through an Ethernet LAN. The processor modules or I/O boxes may have sufficient nonvolatile memory to remember backplane cable connections which have already been made according to user needs, as initially guided by the programmed server management control console. From the memory, replacement of cables when necessary, is facilitated, without the need for assistance by the server management console. If connection changes are needed because of design modifications or additions, the server management control console would again be needed. If a newly made backplane connection is improper or is broken, the diagnostic circuitry will enable the corresponding LEDs to stay lit or to start flashing (depending in the design), thereby signaling need for intervention. Backplane cable connections may be made by semiskilled personnel by using this invention. Also, “hot-add, hot-replace, hot-swap” of connection is easily possible by this invention without interrupting continuity of operation of the system.
