Description
The EHG7706 Series is an Industrial Grade Managed Gigabit Ethernet PoE Switch. UL, CE and FCC certified, it provides highly reliable, fault tolerant, extremely fast network connections in harsh environments.
Versatile high performance: Within its compact DIN-Rail slim type housing design, the EHG7706 series allows you to choose between different port combinations: 1G BASE-T(X) RJ45, IEEE 802.3af/at/bt compliant PoE RJ45, 1G BASE-X SFP and 2.5G Base-X SFP, achieving maximal network performance to suit your exact needs.
High power and redundancy: All models have two terminal blocks to provide dual redundant power inputs with reverse polarity protection, enabling stand-alone fault alarm systems.
Reliability and security: Set up a reliable network environment through RSTP, ERPS Rings and MRP (Manager/Client) redundancy and keep equipment connected all the time, even in case of temporary network breakdowns. And to prevent network intrusions, EHG7706 supports user account, password policy, and authentication interface
managements functions that comply with the IEC62443 standard.
Industry-specific features: Having undergone environmental testing to ensure reliable performance under a variety
of power supply conditions, this switch series is fully compliant for today’s demanding railway applications, as well as complying with essential ground equipment standards. It can also function as an IEEE 1588 hardware-based boundary or transparent clock, offering precise transmission for time-sensitive processes.
APPLICATION CASES
As the capabilities of connected devices continue to improve with technologies like 5G and Wi-Fi 6, networks must also be able to handle faster transmission speeds. 2.5 Gigabit Ethernet (2.5 GbE) supports speeds between 1Gbps and 10Gbps, achieving upgrade for network performance without a complete infrastructure overhaul.
The EHG77xx switch is equipped with 2.5 Gbps SFP slots, making it a powerful tool for connecting advanced applications such as high-resolution CCTV and public Wi-Fi. It can replace slower switches in existing topologies, allowing old and new devices to operate at their full potential.

Specifications taken from the manufacturer datasheet.
Which version do I need?
This page is the EHG7706-4PoE-225SFP: four PoE++ Gigabit RJ45 ports and two SFP slots rated 100/1000/2500 Mbps. ATOP's 2025 brochure lists four codes in this slim family: EHG7704 (4 × non-PoE RJ45), EHG7704-4PoE (4 × PoE++ RJ45, no SFP), EHG7706-225SFP (4 × non-PoE RJ45 plus 2 × 2.5G SFP) and EHG7706-4PoE-225SFP. The '225SFP' suffix means the two 2.5 Gbps SFP slots. Choose this code when PoE++ devices hang off the switch and the uplink runs over fibre or at 2.5 Gbps; choose the EHG7706-225SFP if no PoE is needed. The codes differ by port mix and PoE only, not by region.
Typical applications for the EHG7706-4PoE-225SFP
- High-resolution CCTV cells with a 2.5 Gbps fibre uplink to the NVR
- Public Wi-Fi access points needing PoE++ and a fast backhaul
- Railway onboard and trackside cabinets (EN 50155 / EN 50121-4)
- Upgrading existing topologies to 2.5 Gbps without replacing the backbone
- Edge node in ERPS or RSTP fibre rings
- Slim DIN-rail cabinets operating from -40 to +75°C

EHG7706-4PoE-225SFP — frequently asked questions
What ports does the EHG7706-4PoE-225SFP have?
Four 10/100/1000BASE-T(X) RJ45 ports, all PoE++ to IEEE 802.3af/at/bt, and two SFP slots rated 100/1000/2500 Mbps, six ports in total.
What do the 2.5 Gbps SFP slots add?
They give uplinks faster than 1 Gbps without moving to 10 Gbps infrastructure, which ATOP positions for high-resolution CCTV and public Wi-Fi. The slots are rated 100/1000/2500 Mbps, so they can also run at Gigabit.
What is the PoE power budget?
ATOP's 2025 brochure lists a 240 W PoE budget, with PoE++ able to drive devices that need up to 90 W. Four ports at a full 90 W would exceed 240 W, so plan the combined load against the total.
What power supply does it need?
9-57 V input, with PoE operation from 45 V upwards, on two terminal blocks giving dual redundant inputs with reverse polarity protection. A relay output supports fault alarms.
How does it differ from the EHG7704-4PoE?
Both have the same four PoE++ Gigabit RJ45 ports, 240 W budget and -40 to +75°C rating. The EHG7706-4PoE-225SFP adds two 100/1000/2500 Mbps SFP slots for fibre uplinks.
Which redundancy protocols and certifications apply?
It supports ITU-T G.8032 ERPS, STP, RSTP and MSTP, plus IEEE 1588v2 hardware-based transparent or boundary clock. ATOP's guide ticks EN 50155 / EN 50121-4, with NEMA TS2 on demand, and it is UL, CE and FCC certified.
