Description
The EHG7708 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 EHG7708 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: EHG7708 series provide, in its 8-PoE-Port Version, up to 90W per port and total 180 W power budget. 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, EHG7708 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.

Which version do I need?
This page is the EHG7708-8PoE: eight Gigabit RJ45 ports, all PoE++, and no SFP slots. ATOP's 2025 brochure lists four EHG7708 codes: EHG7708 (8 × non-PoE RJ45), EHG7708-2SFP-225SFP (4 × non-PoE RJ45, 2 × 100/1000 Mbps SFP and 2 × 100/1000/2500 Mbps SFP), EHG7708-8PoE, and EHG7708-4PoE-2SFP-225SFP (4 × PoE++ RJ45 plus the same 2 + 2 SFP slots). ATOP's guide also footnotes a 'c model' of the EHG7708, rated -20 to +60°C and without the hardware-based IEEE 1588v2 E2E transparent clock; it has its own EHG7708C page. Pick the -8PoE when all eight devices take power from the switch; pick the -4PoE-2SFP-225SFP when you need fibre or 2.5 Gbps uplinks.
Typical applications for the EHG7708-8PoE
- PTZ and high-resolution IP cameras on a single 8-port PoE++ switch
- Public Wi-Fi access points in smart-city cabinets
- Railway onboard and trackside cabinets (EN 50155 / EN 50121-4)
- Space-limited control cabinets that need a slim DIN-rail switch
- Edge switch in ERPS or RSTP redundant rings
- Outdoor enclosures operating from -40 to +75°C

EHG7708-8PoE — frequently asked questions
How many ports does the EHG7708-8PoE have, and are they all PoE?
Eight 10/100/1000BASE-T(X) RJ45 ports, all PoE++ to IEEE 802.3af/at/bt, and no SFP slots. For fibre, the EHG7708-4PoE-2SFP-225SFP combines 4 PoE++ RJ45 with 2 × 100/1000 Mbps and 2 × 100/1000/2500 Mbps SFP slots.
What is the PoE power budget?
The EHG7708 series datasheet text gives up to 90 W per port and a 180 W total budget for the 8-PoE-port version. Eight ports cannot all draw 90 W at once, so size the combined load to 180 W.
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 stand-alone fault alarms.
What temperature range is it rated for?
-40 to +75°C operating and -40 to +85°C storage, in an IP30 slim aluminium housing for DIN rail.
How does the EHG7708-8PoE differ from the EHG7708C?
ATOP's guide rates the c model for -20 to +60°C instead of -40 to +75°C and excludes it from hardware-based IEEE 1588v2 E2E transparent clock support. The EHG7708C datasheet text also gives a 120 W total PoE budget, against 180 W here.
Which redundancy protocols and certifications apply?
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 the switch is UL, CE and FCC certified.
