Description

The EHG7608 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, EHG7608 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 EHG7608 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. EHG7608 provide, in its 8-PoE-Port Version, up to 240W 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 EHG7608 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.

Specifications taken from the manufacturer datasheet.

Which version do I need?

This page covers the EHG7608 series. ATOP lists four codes: EHG7608 (8 × Gigabit RJ45), EHG7608-4SFP (4 × RJ45 plus 4 × Gigabit SFP), EHG7608-4PoE-4SFP (4 × PoE RJ45 plus 4 × Gigabit SFP) and EHG7608-8PoE (8 × Gigabit PoE RJ45, the 240 W version). All share Layer 3 routing, the -20 to +70°C rating and the rail and traffic approvals; choose on how many PoE ports and fibre links you need.

Typical applications for the EHG7608

  • Routing between camera, control and corporate subnets in one DIN-rail switch
  • Powering up to 8 IP cameras or access points from a traffic or rail cabinet
  • Traffic control cabinets (NEMA TS2 certified)
  • Railway rolling stock and trackside ground equipment (EN 50155, EN 50121-4)
  • Fibre ring nodes using the 4SFP versions with ERPS or MRP
  • Substation or plant edge networks needing IEEE 1588v2 transparent clock timing

EHG7608 — frequently asked questions

How many ports does the EHG7608 have?

Eight: 8 × Gigabit RJ45, 8 × Gigabit PoE RJ45, or 4 RJ45 (PoE or non-PoE) plus 4 × 1000BASE-X SFP, depending on the version.

What is the PoE budget?

Up to 240 W on the 8-PoE-port version, IEEE 802.3af/at. PoE output needs an input of 45 VDC or higher.

What Layer 3 functions does it have?

IPv4 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 is the difference between the EHG7608 and the EHG7508?

Both are 8-port Gigabit DIN-rail switches with up to 8 PoE ports and a -20 to +70°C rating. The EHG7608 adds Layer 3 routing; the EHG7508 is Layer 2 and is the one ATOP lists as Profinet CC-B certified.

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 it is NEMA TS2 certified for traffic control.
