How does a Cybex KVM switch work?
Normally every computer has a keyboard, monitor and mouse. When using a Cybex KVM switch, a single keyboard, monitor, and mouse is used to switch channels among attached computers. A cable connects the computers to the switch. Cybex KVM switches will fully emulate the mouse and keyboard connections for each computer, even when that computer is not selected. As a result, switching is seamless and you can even reboot servers through the switch.
