The EPSM-10GX is a managed Layer 2+ Ethernet switch module in an ultra-compact 2.2″ x 3.3″ (55×84mm) size offering 24 10/100/1000Mbps copper ports + 2 10Gbps SFI ports. The module is intended to be used on a carrier board. The core Ethernet switching technology is almost fully encapsulated on the module; for many applications, only the «last inch» of magnetics and I/O connectors is required to complete the circuit, enabling easy development of custom form factor Ethernet switch solutions.

The small size, based on the industry-standard COM Express Mini form factor, makes EPSM-10GX a perfect choice for use as a building block for creating custom Ethernet switch solutions in a variety of space-demanding applications, such as drones, ground and underwater vehicles, and robots. EPSM-10GX can also be mounted on a carrier board to create quick Ethernet switching solutions in other industry standard form factors such as VPX. Customers looking for a complete off-the-shelf solution may be interested in Diamond's EPS-24G2X, which provides all of the switch’s features in the industry standard 3.5 inch form factor.

The standard Layer 2 software embedded in the module provides a comprehensive set of Ethernet switch features suitable for a wide range of industrial applications. All features are manageable via a GUI web interface accessible over any port, as well as with a command language accessed via a built-in RS-232 port. A more advanced software package, offering Layer 3 routing performance as well as IEEE1588 PTP protocol, is available upon request. These features are fully supported in the EPSM-10GX hardware.

Two cooling accessory options are available: A heat sink provides convection cooling in a low profile, while a heat spreader provides improved conduction cooling for superior high temperature performance in applications where physical contact with the system enclosure is available.

Two high-speed connectors provide all power and data communications between the module and the carrier board. The first connector provides power, 9 10/100/1000 ports, the serial interface, and a serial LED data stream. Applications requiring 9 ports or less may use just this connector. The second connector contains 3 more 10/100/1000 ports, QSGMII signals for an additional 12-port PHY to provide 12 additional 10/100/1000 ports, and the 2 10G SFI ports.

EPSM-10GX is designed to meet the challenges of vehicle environments with its −40/+85°C operating temperature range and its MIL-STD-202G shock/vibration resistance.

design guide provides instructions for incorporating the EPSM-10GX into your own circuit. Under NDA a complete carrier board reference schematic and PCB layout are available to provide the starting point for a custom Ethernet switch based on the EPSM-10GX. This design is also available off the shelf as Diamond's EPS-24G2X product.
