Additional electronics in the cable (EN 60950-1) provide galvanic insulation between
the HiPath and the PC. This product draws power from both the HiPath and a PC,
and may therefore only be used on HiPath 1100 switches. A USB connection in other
types of equipment will not work with this cable. Siemens does not recommend any
other means of connecting the HiPath 1100 to the PC.
