With the ServSwitch KV9116A KVM Switch, you can use a PS/2 console (keyboard, mouse, and monitor) to control a number of PS/2 and/or USB servers. Switch between 16 servers from a single console. To expand your switching platform to include additional servers, simply cascade units in a master-slave configuration. Cascade up to 136 servers with the 16-port model. The ServSwitch KV9116A KVM Switch is plug-and-play, so you can add or subtract servers almost as quickly as you can plug and unplug cables.
