Diamond Systems EPS-9600 Rugged Layer 3 Ethernet Switch Boards with 10G SFP+ and TSN Options

Where a rugged network carries traffic between separate subnets, needs 10G links and, in some systems, must keep sensors and controllers on one precise clock, a Layer 2 board switch falls short. The Diamond Systems EPS-9600 series answers that with a Layer 3 Ethernet switch board built on the Microchip LAN969x switch family, with 10G switching and Time-Sensitive Networking capability, designed for rugged applications.

Every model shares the same board. Eight 1 Gbps copper ports sit on latching connectors, and two 10 Gbps capable SFP+ sockets take copper or fiber modules. Layer 3 embedded software provides software- and hardware-based IPv4 and IPv6 static routing, VLAN, QoS, RSTP and MSTP, link aggregation, IGMP snooping, port mirroring, storm control, port and queue policers, port-based 802.1X, RADIUS accounting, JSON-RPC and 802.1Qbb priority-based flow control. 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. Management runs through an RS-232 console, and DDR4, flash and eMMC memory sit on board alongside a secure boot device.

The four models cover two feature levels and two cooling options. The EPS-9610-L3-HSK and EPS-9610-L3-HSP are the base Layer 3 builds with a heat sink and a heat spreader respectively. The EPS-9610-L3-TSN-HSK and EPS-9610-L3-TSN-HSP fit the ZL30732B TSN clock for Time-Sensitive Networking with IEEE-1588 PTP, again with a heat sink or a heat spreader. On the base builds a local oscillator takes the place of the TSN clock, so both feature levels share one board design and one software set.

Input power is 12 to 34 V DC. All components and the board itself are rated for -40 to +85 °C operation, and the heat sink and heat spreader options suit different installation needs. The board uses the PC/104 mounting hole pattern, which eases installation in existing mechanical designs, though it is not a PC/104 bus board. The daughterboard connector supports up to 20 extra 1G ports, 16 at 2.5G or six at 10G. The CK-EPS9600-01 cable kit breaks the Gigabit ports out to RJ-45 with power and serial leads, and custom daughterboards are available by request. Diamond positions the family for rugged applications.
