The EPS-24G4X is a managed Ethernet switch based on Diamond’s EPSM-10GX4 switch module. The switch implements all features of the style=’text-decoration: underline’>EPSM-10GX4 Ethernet switch module, including 24 10/100/1000Mbps copper ports and 4 10Gbps SFI ports accessed via SFP+ sockets. Depending on the ordering configuration, the switch contains embedded software supporting Layer 2 switching, Layer 3 routing/switching, and optional IEEE1588 PTP operation.

Two software packages are available, Layer 2+ switching and Layer 3 routing/switching. In addition, IEEE-1588 precision time protocol support is available with a minor modification to support an external precision clock circuit and 1pps signal source provided by the carrier board. All software 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.

EPS-24G4X is designed specifically to meet the challenges of vehicle and other rugged environments, with its -40/+85°C operating temperature range, 50% thicker PCB, latching I/O connectors, and its MIL-STD-202G shock/vibration resistance. A wide-range input power supply with built-in transient protection provides compatibility with a range of industrial and vehicle power supplies. The board also forms the heart of Diamond’s SabreNet-24000 rugged Ethernet switch. Cooling for EPS-24G4X is provided via two heat sinks: a low-profile heat sink between the carrier board and the EPSM module and a taller heat sink for the EPSM module.

The EPS-24G4X is included as part of the EPSM-10GX4 development kit. Schematics and bill of materials are included to simplify the development of custom advanced Ethernet switching solutions based on the EPSM-10GX4 module.
