Tripp Lite's 2-User 16-port NetDirector 1U Rackmount Matrix KVM Switch is the optimal solution for controlling multiple computers (combination of PS/2, USB or Sun) by two independent, simultaneous users. A single unit occupies a mere 1U of rack space, yet can control up to 16 directly connected computers. A maximum of 1,024 computers can be connected through a combination of daisy-chaining and cascading. RJ45 connections allow signals to travel up to 150 meters away (500 ft.) using ordinary Cat5 cable, while maintaining video resolution. Use either PS/2 or USB console equipment to connect to PS/2, USB or SUN Servers.
