IEC-320 power entry connector. This power supply connects to the
Model 2701/I by means of a barrel jack on the rear panel. Many interna-
tional power cords are available for the universal power supply.
The Model 2701/I powers up as soon as it is plugged into an AC outlet--
there is no power switch..
