A method and system for detecting the operating voltage of a disk array chassis or disk array enclosure ("DAE") attached to a fibre channel loop and adjusting the operating voltage of the entire loop based on the operating voltage detected for each disk array chassis attached to the loop is disclosed. In one embodiment, an input voltage to a DAE is detected and a control signal corresponding to the input voltage is generated. The control signal is input to a voltage selection device that inputs an operating voltage corresponding to the control signal to the operating voltage supply of the DAE.
