Electronic board identification

摘要

The invention electronically identifies whether a computer module board is placed in the correct mechanical slot in a computer frame. A conductive line is connected to at least one electronic connector location in each mechanical slot in a computer frame. A computer module has open circuit electrical connectors which if put in the correct slot will mate with the locations in the slot in the frame which are connected to the conductive line. The other electrical connections which are used for identification are connected to a ground plane in the computer module board. A voltage source is connected through a resistor to a conductive line in the computer frame producing a high signal. If any computer module board engaged in a slot of the computer frame is in the incorrect slot, a low signal will be caused indicating the fault. The fault signal will be supplied to a power supply controller which prevents operating power from being provided to the computer boards.
