A beacon device is provided in proximity to a computing system within a computing center. A request to locate the computing system in the computing center is triggered on a central control unit. In response to the request to locate the computing system, the control unit generates specification data for a unique radio signal identifier, sends an activation request and the specification data to the beacon device, and provides the specification data to a portable device and stores the specification data on the portable device. In response to receiving the activation request, the beacon device sends a radio signal identifier generated from the specification data.
