Installation
If you are connecting the keyboard to a switchbox, connect the cables to the switch in
this order:
1. Mouse
2. Video
3. Keyboard
IMPORTANT: This cable connection sequence is particularly important later when you install
new devices to your system. You can connect a mouse and/or keyboard to the switch when
the system is running. When you connect the new device, the switch recognizes the device
and configures it to the settings of the currently selected computer. This allows you to replace
failed devices without having to restart the system.
