A communication link includes a first conductor configured to transmit data between a plurality of connected network devices. The communication link further includes an identification device configured to transmit an output that identifies the communication link when power is supplied to it and a second conductor configured to complete an electrical circuit when it receives the power from a particular device in the plurality of connected network devices. The identification device is coupled with the electrical circuit by a switch. The communication link also includes a logic module configured to receive an identification instruction in the data transmitted between the plurality of connected network devices. The logic module is also configured to, in response to receiving the identification instruction, actuate the switch to supply the identification device with power and transmit the output at the identification device.
