Tripp Lite?s 8-port KVM Console Switch is the optimal solution for controlling multiple computers from one keyboard, mouse and monitor. This single unit combines an 8 port KVM switch, keyboard, 15" LCD monitor and touchpad - all in a mere 1U of rack space. Stores neatly in the rack, pulls out when needed. Control up to 504 computers from this single console by daisy-chaining additional 16 port KVM switches (model B022-016). Easily switch ports using the touchpad with On Screen Display (OSD) or by using the keyboard "hot key" functions. In addition to controlling PS/2 systems, you can also control Sun and USB systems when using the appropriate adapter. Works on all operating systems. Remember to order 1 #P774-006(6ft.), 1 #P774-010(10ft.) or 1 #P774-015(15ft.) per port.
