Diamond Systems EPS-8000-XT Epsilon 8-Port Gigabit Ethernet Switch

The Diamond Systems EPS-8000-XT Epsilon is a managed Layer 2+ 8-port Gigabit Ethernet switch engineered for industrial environments requiring reliability in harsh operating conditions. This PC/104 form factor device (3.55 x 3.775 inches) delivers non-blocking wire-speed switching across eight 10/100/1000 Mbps ports with full jumbo frame support. It operates autonomously via built-in 8051 microcontroller management or integrates with host SBCs through in-band web interface and out-of-band RS-232 serial port control.
