Diamond Systems EPS-24G4X-L3 Rugged Layer 3 Managed 24 Port Gigabit Ethernet Switch with 4 10G SFP+ Ports
Extended TempEPS-24G4X-L3 Overview
Once a vehicle or rugged network is split into several subnets, traffic between them needs routing, and a separate router adds space, power and another unit to qualify. The EPS-24G4X-L3 is the Layer 3 build in the Diamond Systems EPS-24G4X series: a managed Ethernet switch board that Diamond designed for vehicle and other rugged environments, running routing and switching on the same board.
It carries 24 10/100/1000 Mbps copper ports with non-blocking wire-speed performance and four 10G SFI ports on SFP+ sockets, with 4 MB of packet memory. Diamond’s Layer 3 routing and switching software runs on the board, and every feature is manageable through a web GUI over any port, a command language on the built-in RS-232 port or SNMP v1/v2c/v3. Customer branding can add your logo, colour scheme and part numbers to the GUI and serial interface.
On top of the Layer 2+ set of 8K MAC addresses, 4K IEEE 802.1Q VLANs, IEEE 802.3ad link aggregation, RSTP and MSTP, the Layer 3 package adds hardware- and software-based IPv6 static routing, RFC 2328 OSPFv2 dynamic routing, RADIUS accounting and port and queue policers. The EPS-24G4X is the Layer 2+ build, and the EPS-24G4X-1588 adds an IEEE-1588 PTP clock circuit. Our comparison of Layer 2 and Layer 3 switches sets out when routing belongs in the switch.
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. Cooling comes from two heat sinks on the switch module assembly. The board is part of the EPSM-10GX4 development kit, whose schematics and bill of materials support custom carrier designs.
