Epsilon-12G2 is a managed Layer 2+ 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.
Epsilon-12G2's advanced Ethernet switch board includes two innovative features that enable automatic power savings. The switch can detect unused Ethernet ports on network devices and power them down or place them in stand-by mode. Additionally, the switch actively adjusts the power level needed based on cable length, saving energy on links shorter than the 100m maximum specified length.
Epsilon-12G2 comes loaded with all required firmware, enabling its immediate operation without any development effort. The included web interface provides an intuitive GUI for use in configuring and managing switch functionality.
