The modular KVM switch ensures server connection via USB or PS / 2 and VGA. The DIGITUS 17 "or 19" modular console, keypad and the appropriate set of cables are necessary for operation. High-quality KVM switch modules with an IP function (optional) are ideal for use in small to medium-sized server rooms where administrator access must be provided at any time from anywhere. They provide a direct connection to the browser from a local console or through an optional IP module via an existing internet connection.
