2. INTRODUCTION
Epsilon-8100 is a managed, 8-Port Gigabit Ethernet Switch with wide power supply voltage input and a serial
management port. Epsilon-8100 offers 10/100/1000Mbps copper twisted pair ports on a PC/104 format board. 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 em5V supply.
Highly Advanced Gigabit Ethernet Switch
Epsilon-8100 is an 8-port Gigabit Ethernet switch in the compact PC/104 form factor. Epsilon-8100 operates
standalone, but can be included in any PC/104 board stack.
Layer 2+ Managed Switch
Epsilon-8100
’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-8100 is powered through a wide v5-36V DC/DC power supply input.
Rugged Design
Extended temperature operation of -40°C to +85°C is tested and guaranteed. Epsilon-8100 was designed with
harsh applications in mind. Latching connectors provide increased reliability.
Software Support
The switch is ready to plug into your application without any driver installation or firmware upgrades. A web
interface and a CLI provide an intuitive GUI for configuring and managing the switch.
