Abstract:
1. A computer system, comprising: a baseboard having a first side and a second side; wherein the first side and the second side define a first key opening; a first key pad located on the first side, wherein the first key pad is grounded; a second key pad located on the second side, wherein the second key pad is aligned with the first key pad via the first key opening, wherein the second key pad is coupled to a first voltage source, and wherein the second key pad is electrically isolated from the first key pad; a mezzanine card interface coupled to the baseboard; and a keying mechanism coupled to interface with the baseboard through the first key opening, wherein coupling the keying mechanism to the baseboard shorts the second key pad to the first key pad and initiates a first key signal, and wherein the first key signal operates to permit a first operating voltage to power the mezzanine card interface.
