Diamond Systems EPS-9610-L3-HSP Rugged 8-Port Gigabit + 2-Port 10G SFP+ Managed Layer 3 Switch with Heat Spreader

A sealed enclosure that routes traffic between subnets needs a Layer 3 switch that passes its heat into the chassis rather than relying on airflow. The EPS-9610-L3-HSP is the base Layer 3 model with a heat spreader in the Diamond Systems EPS-9600 series, a Layer 3 Ethernet switch board built on the Microchip LAN969x switch family and designed for rugged applications.

It provides eight 1 Gbps copper ports on latching connectors and two 10 Gbps capable SFP+ sockets that take copper or fibre modules. Layer 3 embedded software adds software- and hardware-based IPv4 and IPv6 static routing, with an RS-232 console, JSON-RPC and RADIUS accounting for management. This build fits a local oscillator in place of the TSN clock used on the TSN models.

The software covers VLAN, QoS, RSTP and MSTP, link aggregation, IGMP snooping, port mirroring, storm control, port and queue policers, port-based 802.1X, 802.1Qbb priority-based flow control and jumbo frames. Our article on how a military Ethernet switch is built covers why latching connectors and conduction cooling suit harsh installs. The EPS-9610-L3-HSK is the same build with a heat sink, and the EPS-9610-L3-TSN-HSP adds Time-Sensitive Networking with IEEE-1588 PTP.

Input power is 12 to 34 V DC, and all components and the board are rated for -40 to +85 °C operation, with a heat spreader for cooling. The board uses the PC/104 mounting hole pattern, which eases installation in existing mechanical designs. A 100-pin board-to-board connector on the underside takes standard or custom daughterboards for up to 28 total 1G, 2.5G and 10G ports and 88 Gbps total bandwidth. The CK-EPS9600-01 cable kit breaks the Gigabit ports out to RJ-45 with power and serial leads.
