Warning When SBx908 devices are connected with VCS stacking cables (either
HS-STK-CBL or XEM-STK-CBL), each individual stack member chassis must be
additionally grounded by using the rear grounding-terminal on each device. In
order to avoid large circulating ground currents, the wires of each grounding
cable must be 18AWG or thicker.
