Fanless Industrial PC - Quad Gigabit LAN Edge Gateway Platform The IEXP-712 is a fanless, all-aluminium industrial computer designed for network edge duty. Four independent Intel Gigabit controllers - three I210-AT plus one I219-LM - give you four isolated RJ45 segments instead of a switched port, so routing, firewalling, protocol conversion and traffic capture can run on dedicated interfaces. Why this platform suits edge and network builds Four native Intel NICs - I210-AT
