Abstract
By utilizing a transmitter that plugs into a power socket of a piece of electrical equipment, that equipment may be locatable using a specialized power source that interacts with the transmitter. The specialized power source sends a command signal across a power cable and causes the transmitter to send a response signal. The response signal is received by one or more receivers, and the position of the equipment within its corresponding cabinet/rack can be determined. The response signal can be sent using a number of different techniques, such as ultrasonic or infrared.
