A system for remote identification comprising: a power sourcing device; a power ready patch panel comprising a first resistive element and at least one of a second resistive element, a multi-bit storage device and an open connection; a first electrical path between the power sourcing device and the first resistive element; and a second electrical path between the power sourcing device and the at least one of a second resistive element, a multi-bit storage device and an open connection; the power sourcing device being operable to obtain a value associated with the first resistive element via the first electrical path, and in the event the obtained value is indicative that a multi-bit storage device is connected to the second electrical path, obtain configuration information from the multi-bit storage device via the second electrical path.
