Diamond Systems EPS-24016-104 Extended Temperature Managed PC/104 16 Port Ethernet Switch with Dual SFP Ports

A vehicle or military system built on a PC/104 stack often needs more Ethernet ports than the host SBC provides, and an office switch will not cope with the vibration or the temperature range. The EPS-24016-104 is the 16-port PC/104 Ethernet switch in the Diamond Systems EPSILON-2400 series, designed for industrial, on-vehicle and military use and able to run on its own or alongside a host computer.

It provides 16 Gigabit copper ports (10/100/1000 Mbps) with non-blocking wire-speed performance, all on latching connectors. Switching is managed Layer 2+, run by a built-in microcontroller that keeps dual application images on board. You manage it through an in-band web interface over any Ethernet port or a command-line interface over the RS-232 port, and it ships loaded with firmware, so it runs without development work.

Network features include 4K IEEE 802.1Q VLANs with push and pop of up to two tags, 8K MAC addresses, eight priorities and eight CoS queues per port, per-queue and per-port shaping and policing, storm control, IEEE 802.3ad link aggregation, RSTP and MSTP, IEEE 802.1X and jumbo frames at all speeds. If you are weighing up the options, our explainer on what a managed switch does covers the basics. The EPS-24026-104 adds eight more copper ports and two SFP sockets, and the EPS-8130 covers eight ports on the same footprint.

Input is +5 to +34 V DC through a built-in DC/DC supply, and the board draws 10.4 W maximum at +12 V with all 16 ports active. It operates from -40 to +85 °C, and latching connectors give better protection against vibration. The board follows the PC/104 form factor and ships with a heat sink. The DK-EPS24016 development kit pairs the switch with a cable kit and an LED accessory board.
