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. |

DETAILED DESCRIPTION The present invention is directed to a backplane cable connection system between at least one processor and at least one I/O unit.
This invention easily lends itself to "hot-add, hot-swap and hot-repair" of backplane cable connections, without the need for skilled manual labor.
The backplane cable connections are expediently so programmed using the invention that a programmed control unit prompts a technician or other semi-skilled person to complete each connection as required by the user's needs.
Each connection which is completed will cause an LED or other such visual means to light up.
When each connection is made manually, a diagnostic circuitry which is part of the system verifies the correctness of each manual cable connection made, and the connection is verified as proper by turning off the LEDs (visual means) corresponding to the connection made.
If a manual connection which is just made is either incorrect or broken, the diagnostic circuitry keeps the LEDs (or visual means) on/flashing, thereby indicating that corrective action is needed.
In the absence of the automated cable management of the present invention, it would be a formidable task to find out if a wrong cable connection exists or, if a connection already made is proper but broken.
The present invention provides an improved backplane cable connection configuration preferably in the form of an automated cable connection identification mechanism comprising: means for providing an identification of connection terminals on a processor/I/O box, to be connected to connection terminals on a processor or I/O box; each of the connection terminals having a visual means which can turn on or off to indicate a connection cable being manually inserted to establish a connection; a diagnostic circuitry to check if identified connection terminals are properly manually connected in accordance with customer requirements, said diagnostic circuitry having the capability of turning off the visual means relating to those connection cables which are properly connected as verified by the diagnostic circuitry, and ensuring that connection cables with faulty or broken connections will have their corresponding visual means on or blinking
