Epsilon-12G2 is a managed Layer 2+ managed Ethernet switch module offering twelve 10/100/1000Mbps copper twisted pair ports and two SFP optical sockets in a COM Express form-factor board.

Epsilon-12G2 can be used standalone, without any connection to a single board computer, or in conjunction with a host SBC. The module’s built-in microcontroller handles configuration and management. On-board memory holds dual application images, boot code, MAC addresses, and other parameters, and can also be used for program execution.

An RS-232 serial port enables communication between the module’s on-board management microcontroller and a host processor. Epsilon-12G2’s built-in microcontroller is also accessible via a web management interface over one of the Ethernet ports.

Input power is provided through the built-in, wide-range +5 to +40VDC power supply, enabling operation using industrial power sources.

To address the temperature extremes of fixed and mobile applications in both indoor and outdoor environments, the module supports fanless operation over -40°C to +85°C.
