The KL1516Ai Dual Rail LCD KVM Switch is a control unit that allows secure access up to 16 computers from a single KVM (keyboard, video, and mouse) console. It consists of an integrated LCD monitor, keyboard, and touchpad in a 1U rack-mountable retractable sliding housing. The LCD and keyboard/touchpad modules slide independently of each other. To maximize space in your data center, the keyboard/touchpad module slides back to " hide away " when not in use, while the thin profile LCD monitor rotates back - flush against the rack - allowing convenient monitoring of computer activity.
