EPS-24G4X Overview
A vehicle or harsh-environment network with two dozen devices needs gigabit access ports and 10G uplinks from one rugged board, rather than a stack of commercial switches. The EPS-24G4X is the Layer 2+ build in the Diamond Systems EPS-24G4X series: a managed Ethernet switch board that Diamond designed for vehicle and other rugged environments, and the board at the heart of Diamond’s SabreNet-24000 rugged Ethernet switch.
It provides 24 10/100/1000 Mbps copper ports with non-blocking wire-speed performance and four 10G SFI ports on SFP+ sockets. The EPS-24G4X runs Diamond’s Layer 2+ switching software with 4 MB of packet memory. Every software feature is manageable through a web GUI over any port, through a command language on the built-in RS-232 port and through SNMP v1/v2c/v3. Customer branding can place your logo, colour scheme and part numbers on the GUI and serial interface.
The Layer 2+ package supports 8K MAC addresses, 4K IEEE 802.1Q VLANs, 8K IPv4 and IPv6 multicast groups and jumbo frames at all speeds, with IEEE 802.3ad link aggregation, RSTP, MSTP, IEEE 802.1X and 8 QoS queues per port. Inside, an EPSM-10GX4 switch module provides the core switch and 12 PHYs, while the carrier holds the other 12 PHYs and the remaining circuitry. The EPS-24G4X-L3 adds Layer 3 routing, and the EPS-24G4X-1588 adds IEEE-1588 PTP. Our guide to board-level Ethernet switch modules explains the module and carrier approach.
At 24 V input the board draws 13 W with all ports idle, 20 W with all 24 copper ports active and 26 W with every port active, from a wide-range supply with built-in transient protection. It is rated down to -40 °C, with latching I/O connectors and MIL-STD-202G shock and vibration resistance. Two heat sinks cool it, one low-profile under the module and a taller one on top. The board is included in the EPSM-10GX4 development kit, with schematics and bill of materials for custom carrier designs.

Official Diamond Systems UK Distributor
Things Embedded is an official Diamond Systems UK distributor, supplying the EPS-24G4X for UK defence and vehicle programmes. Within the Diamond range the EPSM-10GX4 module is the switch core of this board for teams designing their own carrier, and the EPS-12G2 series covers smaller networks with 12 copper ports.
With Layer 2+ software the EPS-24G4X sits among our Ethernet switch boards, our embedded network switches and our managed Ethernet switches. Where 24 copper devices need 10G uplinks and Layer 2 management is enough, this is the model to specify.
