Figure 1. Functional Block Diagram
Epsilon-12G2 is an 14-Port managed Gigabit Ethernet switch module offering 10/100/1000Mbps copper twisted
pair ports, one 1G SFP socket, and one 2.5G SFP socket on a COM Express form factor board. Epsilon-12G2
operates standalone, requiring no connection to a single board computer in the stack.
Epsilon-12G2 is a Layer 2+ managed Ethernet switch with built-in microcontroller and memory for configuration
and management. The Flash memory holds dual application images along with the boot code, The SRAM is used
for program execution and storing the MAC addresses. The EEPROM holds the configuration parameters. .
An RS-232 interface is provided to enable communication between the on-board management microcontroller
and a host processor through a CLI interface. The microcontroller is also accessible through one of the Ethernet
ports via a web management interface.
Power is provided through the +5-40VDC wide-range DC power supply built into the board, enabling use with
industrial power sources.
