This ATEN product is a KVM-over-IP switch supporting 1 local user and up to 4 remote users sharing access, described as "16P" (likely a 16-port capacity) with Cat5 (C5) cabling and software-based switching. KVM-over-IP switches let IT administrators access and control multiple servers' keyboard, video, and mouse remotely over a network, rather than needing physical access to each server — essential for managing racks of servers in a data centre or server room from a central location or off-site. ATEN is an established manufacturer of KVM and IT infrastructure management hardware; this model targets server-room and data-centre management use rather than end-user desktop KVM switching.
