Epsilon-8130 is a managed Layer 2+ Ethernet switch module offering eight 10/100/1000Mbps copper twisted pair ports in the compact PC/104 form factor. It is designed for rugged applications including industrial and on‑vehicle. EPS-8130 is a direct replacement for the previous EPS-8100 and is fully backwards compatible with the previous product in all key respects.

Epsilon-8130 is a standalone switch that does not require any host computer interface. All switch functions are managed by a 416MHz MIPS processor embedded directly into the switch. The processor is accessed via an in-band web interface over one of the Ethernet ports or via an out-of-band command-line interface over an RS-232 serial port. The integrated web interface provides an intuitive GUI for use in configuring and managing all switch functionality. On-board memory holds dual application images, boot code, MAC addresses, and other parameters, and can also be used for program execution.

Epsilon-8130’s advanced Ethernet switch chip 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-8130 was designed for use in vehicle and harsh environment applications. All I/O connectors are latching, providing enhanced reliability over the RJ-45 connectors used in commercial Ethernet switches.

The wide range 5-36V input power supply is compatible with all common vehicle and industrial power sources. The −40°C to +85°C operating range makes Epsilon-8130 suitable for use in outdoor and vehicle applications.

Epsilon-8130 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.

EPS-8130 is available with a heat sink, a heat spreader, or no cooling solution. Both heat sink and heat spreader support the full −40 to +85C industrial temperature range.

  • Model EPS-8130 uses a low profile heat sink that fits within the PC/104 11.2mm height limit above the PCB. It is positively fixed in place with two screws.
  • Model EPS-8130-XT has a heat spreader that is the same size as the PCB. It has two mounting hole patterns to support both SAE (#6-32) and Metric (M3) fasteners.
  • Model 9113190 is the board assembly without any cooling solution for convenience of customers who have designed their own cooling solution into their system enclosure. This model will operate safely at up to near room temperature, however suitable cooling is needed to achieve reliable operation at elevated temperatures.
