The ATEN KH1508AI Cat 5 High-Density Over the NET KVM switch is an 8-port device in a 1U high housing allowing local and remote operators to monitor and access the entire enterprise data centre over the Internet using a web-based browser. The KH1508AI features Cat 5e/6 cable to link to CPU modules attached to the servers, this arrangement has several advantages over standard KVM cabling. In addition to TCP/IP connectivity, the KH1508Ai provides KVM ports for a locally attached USB and / or PS/2 console and a Mini-USB port for a VNC Laptop console - allowing access and control from the data centre, over the Net, or from a laptop's USB connection. This is a single bus unit, so although up to 32 users may be logged in simultaneously only one operator has control.
