Abstract: A cabling modification control unit controls modification of electronic device cabling with physical locks and includes a processing unit and a communication unit. The processing unit is configured to process a cable modification request and configured to generate a control signal based on the result of processing the cable modification request. The communication unit is configured to communicate the control signal to an electronic device component. The control signal is configured to control a physical lock associated with the electronic device component to permit or prevent modification of the electronic device cabling. The electronic device component includes a port configured to connect to the electronic device cabling and a physical lock that is configured to prevent connection or disconnection of the electronic device cabling to the port based on the control signal received from the modification control unit.
