Tripp Lite's 32-port NetDirector 1U Rackmount Matrix KVM Switch is the optimal solution for controlling multiple computers (combination of PS/2, USB, or Sun) by four independent, simultaneous users. A single unit occupies a mere 1U of rack space, yet can control up to 32 computers. A maximum of 4, 096 computers can be connected through a combination of daisy-chaining and cascading. RJ45 connections allow signals to travel up to 150 meters away(500ft), 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.
