摘要

A KVM switch is disclosed having on screen display (OSD) circuitry coupled to a user workstation for providing a user a convenient interface by which to operate the KVM switch. First switching circuitry coupled to a plurality of computers and coupled to the OSD circuitry allows a user to access any of the computers or the control functions of the KVM switch. Second switching circuitry coupled to switch electrical power to the computers and further coupled to the OSD circuitry allows a user of the KVM switch to selectively control electrical power to the computers.
