INTRODUCTION
Epsilon-12G2 is a managed, 14-Port Gigabit Ethernet Switch with wide power supply voltage input and a serial
management port. Epsilon-12G2 offers twelve 10/100/1000Mbps copper twisted pair ports, one 1G SFP socket,
and one 2.5G SFP socket on a COM Express format board. The board is standalone, so no bus connectors are
required. An RS-232 interface is provided to enable communication between the on-board management
microcontroller and a host processor through a command line interface (CLI). A wide-range DC power supply is
built into the board to allow it to be used with industrial power sources as well as the typical embedded +5V
supply.
Highly Advanced Gigabit Ethernet Switch
Epsilon-12G2 is a standalone 14-port Gigabit Ethernet managed switch in the COM Express form factor. It delivers
a comprehensive, end-to-end carrier Ethernet solution supporting MEF service delivery and timing over packet
solutions for IEEE 1588 and synchronous Ethernet.
Layer 2+ Managed Switch
Epsilon-12G2
’s Ethernet switch chip includes a built-in microcontroller for configuration and management. It can
be accessed either through the on-board RS-232 port or one of the Ethernet ports.
Wide Power DC/DC Power Supply
Epsilon-12G2 can be powered through a wide v5-40V DC/DC power supply input.
Rugged Design
Extended temperature operation of -40°C to +85°C is tested and guaranteed. Epsilon-12G2 was designed with
harsh applications in mind. Latching connectors provide increased reliability.
Software Support
The Epsilon-12G2 switch is ready to plug into your application without any driver installation or firmware
upgrades. An intuitive GUI web interface and a command line interface provide means for configuring and
managing the switch.
