This ATEN Altusen unit is a 16-port, 19-inch rack-mount LCD IP KVM switch — a device that lets IT administrators control up to 16 servers from one integrated keyboard, monitor and touchpad drawer, or remotely over the network via Cat5/IP with full-HD video for one remote and one local user simultaneously. It slides into a standard rack (D.Rail mounting), bundles a keyboard and EU power cord, and is built for data centres and server rooms where physical access to every machine's own monitor/keyboard is impractical. This is infrastructure hardware for IT departments managing multiple servers centrally, not a consumer or single-PC product.
