Diamond Systems EPS-12002L-HSK Compact Managed Ethernet Switch with 12x 1GbE Ports + 2x 1/2.5/5/10GbE SFP+ sockets, Layer 2 software & heat sink
Extended TempWide TempEPS-12002L-HSK Overview
Vehicle and industrial networks often need a dozen copper devices and a fibre uplink on a switch small enough to sit beside the computer. The EPS-12002L-HSK is the Layer 2+ build with an integrated heat sink in the Diamond Systems EPS-12002L series. Diamond builds it around its EPSM-10GX Ethernet switch module, mounted on a carrier board that provides power, magnetics and connectors, so it arrives as a complete standalone Ethernet switch board.
The board carries 12 10/100/1000 Mbps copper ports for twisted-pair links and two SFP+ sockets that run at 1, 2.5, 5 or 10 Gbps with fibre or copper transceivers, and all ports switch at non-blocking wire speed. It runs Diamond’s Layer 2+ switching software. You manage it through a GUI web interface reached over any port, or through a command language on the built-in RS-232 port when a field engineer connects locally. Diamond also offers software customisation and can put your logo, colour scheme and part numbers on the GUI and serial interface.
The Layer 2+ software handles 8K MAC addresses, 4K IEEE 802.1Q VLANs and 8K IPv4 and IPv6 multicast groups, with jumbo frames at all speeds. Each port has 8 priorities and 8 QoS queues with scheduling, and IEEE 802.3ad link aggregation works on Layer 2 to Layer 4 information. RSTP and MSTP manage redundant paths, alongside IEEE 802.1X and broadcast and multicast storm control. Where routing between subnets is needed, the EPS-12002L-HSK-L3 adds Layer 3 software with the same heat sink, and the EPS-12002L-HSP swaps the heat sink for a heat spreader. Our guide to VLANs explains how segmentation works.
A 5 to 36 V DC input suits a range of industrial and vehicle power supplies, and the board operates from -40 to +85 °C. It uses latching I/O connectors, and Diamond specifies MIL-STD-202G shock and vibration resistance. The integrated heat sink sits over the switch module, which suits enclosures with room above the board for its fins.

Official Diamond Systems UK Distributor
Things Embedded is an official Diamond Systems UK distributor, supplying the EPS-12002L-HSK for UK vehicle and industrial programmes. Within the Diamond range the EPSM-10GX is the 26-port switch module this board is built on, for teams designing their own carrier, and the EPS-24G4X series offers 28 ports with four 10G ports where more links are needed.
As a compact Layer 2+ board, the EPS-12002L-HSK sits among our board-level Ethernet switches, our embedded network switches and our wider Ethernet switches. Where a vehicle network needs 12 copper ports, two 10G SFP+ uplinks and a finned heat sink, this is the build to specify.
