Description
The EHG7604 Series is an Industrial Grade Layer-3 Managed Gigabit Ethernet PoE Switch. Designed to provide a highly reliable, fault-tolerant, extremely fast network connection in a harsh environment, EHG7604 Series equips two terminal blocks to provide dual redundant power inputs with Reverse Polarity Protection and allows field engineers to build up a stand-alone fault alarm system. EHG76XX family is UL, CE, FCC and NEMA TS-2 certified, allowing the use in Traffic Control Applications.
Within its compact DIN-Rail housing design, the EHG7604 series allows you to choose between different port combinations: 10/100/1000 BASE-T(X) RJ45 port, 1000 BASE-X SFP port and IEEE 802.3af/at complaint PoE RJ45. EHG7604 provide, in its 4-PoE-Port Version, up to 120W power budget. Layer-3 Features support IPv4, RIP v1/v2, OSPF v1/v2 and many more.
This is the right choice if you want to set up a Reliable network environment with its intelligent features and keep equipment connected all the time, even in case of temporary network breakdowns through RSTP, ERPS Rings and MRP (Manager/ Client) redundancy. And that’s not all. Designed specifically for Automation, it is Profinet CC-B, MAC-based Black List/White List, IEEE 802.1x, RADIUS, TACACS+, etc., and keep your network safe.
Automation and IoT ready: Conforming with Profinet CC-B v2.33 makes EHG76XX the perfect candidate for being the backbone of your Industrial automation.
EN50155 and EN50121-4 Certified: Having undergone environmental testing to ensure reliable performance under a variety of power supply conditions, such as voltage variations, power interruptions, and supply changeovers, this switch Series is fully EN50155-certified for today’s demanding railway applications, as well as complying with essential sections of EN50121-4 for ground equipment.

Which version do I need?
This page covers the EHG7604 series. ATOP lists five codes: EHG7604 (4 × Gigabit RJ45), EHG7604-4PoE (4 × Gigabit PoE RJ45, the 120 W version), EHG7604-2SFP (2 × RJ45 plus 2 × Gigabit SFP), EHG7604-2PoE-2SFP (2 × PoE RJ45 plus 2 × Gigabit SFP) and EHG7604-4SFP (4 × Gigabit SFP). All share Layer 3 routing, the -20 to +70°C rating and the rail and traffic approvals, so choose on the copper, PoE and fibre mix.
Typical applications for the EHG7604
- Routing between VLANs or subnets at a remote cabinet without a separate router
- Traffic control cabinets (NEMA TS2 certified)
- Railway rolling stock and trackside ground equipment (EN 50155, EN 50121-4)
- Powering up to 4 IP cameras or access points at the edge
- Small fibre ring nodes using ERPS or MRP
- Networks that need IEEE 1588v2 transparent clock timing

EHG7604 — frequently asked questions
What routing does the EHG7604 support?
IPv4 unicast static routing, RIP v1/v2 and OSPFv2, with ATOP's Layer 3 range also listing BGP, VRRP, DVMRP, PIM-DM/SM/SSM and a DHCP server.
What port options are available?
Four ports: 4 × Gigabit RJ45, 4 × Gigabit PoE RJ45, 2 RJ45 plus 2 SFP, 2 PoE RJ45 plus 2 SFP, or 4 × 1000BASE-X SFP.
What is the PoE budget?
Up to 120 W on the 4-PoE-port version, IEEE 802.3af/at. PoE output needs a 45 VDC or higher input.
Is it certified for rail and traffic use?
Yes. ATOP states it is EN 50155 certified and complies with the essential sections of EN 50121-4, and the EHG76xx family is NEMA TS2 certified.
What is the difference between the EHG7604 and the EHG7504?
The EHG7604 adds Layer 3 routing to the same 4-port hardware options. ATOP's 2025 guide lists Profinet CC-B certification for the EHG7504, not for the EHG76xx family, so choose the EHG7504 for a certified Profinet network.
What security functions are included?
MAC-based black list and white list, IEEE 802.1X, RADIUS, TACACS+ and ACLs, as security features based on IEC 62443.
