ABSTRACT:
A system and method for automatically determining a physical location of one or more units in a rack, including: using one or more physical cables between rack units; cascading a first signal through the one or more units located in the rack, the first signal being encoded with a unit number and a physical parameter; and creating a rack ID by utilizing hardware parameters, the hardware parameters being determined by: detecting a second signal that exists from a bottom unit, the bottom unit located at the bottom of the rack; and using a third signal to send data between the one or more units in the rack by manipulating void spaces within the rack, the third signal being either cabled or an optical signal.
