The CS1716A KVM allows access to 16 directly connected computers, & through Daisy chain architecture as many as 512 total servers may be controlled from a single keyboard, mouse & monitor. To simplify installation & to keep track of so many servers a custom ASIC (patent pending) provides an auto-sensing function that recognizes the position of each KVM station in the chain. A front panel USB (Universal Serial Bus) port provides server access to USB (Universal Serial Bus) devices such as Hard Drives, or CDROM s, eliminating the need to physically connect a storage device to a server to install patches or updates. The CS1716A will accommodate either PS/2 or USB (Universal Serial Bus) keyboards & mice, & will connect to a mixture of PS/2 & USB (Universal Serial Bus) servers. Please note: networking components such as switches, routers, KVM & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
