Abstract
A system and method for determining a routing of cables between devices within a computer chassis. The method comprises signaling, for each of the devices, deactivation of a selected signal line of each cable. Then, one of the devices is requested to activate its selected signal line for one of the cables. The selected signal line is coupled to an input/output (I/O) data port of a driver circuit associated with the devices. The voltage on the I/O data port is sensed to determine which device is coupled to and in control of other device(s).
