Ethernet Switches

Belden announces new Hirschmann Ethernet switches. World’s first manufacturer to offer switches with integrated PRP and HSR redundancy protocols.

Belden has extended its Hirschmann™ product program to include Ethernet switches from its new RSP family, which offer redundancy with zero switch-over time.

They are especially designed for use in the field-level networks of power supply companies, but they also can be used in any situation where uninterrupted communication is required, for instance for mechanical engineering projects or drives for production facilities.

These extremely robust fanless switches have eleven ports, three of which can be used for SFP transceivers. They support Fast (100 BASE-FX) or – optionally – Gigabit Ethernet (100/1000 BASE-FX). The remaining eight ports can be used either for 100 BASE-TX or as a combination of four SFP transceivers and four TX ports.

Additional features include comprehensive management, diagnostic and filter functions plus a variety of redundancy methods and markedly expanded security mechanisms.

In addition to the standard configuration, Hirschmann also offers a version that supports highly precise synchronization compliant with IEEE 1588v2, plus PRP (Parallel Redundancy Protocol) and HSR (High-availability Seamless Redundancy). This means that, for the first time, it is now possible to implement networks that guarantee uninterrupted data communications with the attached systems and can thus – in the case of the electricity supply industry – guarantee reliable power supplies to end customers at all times.

These switches have high vibration resistance and extensive resilience to magnetic fields and electrostatic discharges.

Redundancy methods such as PRP, HSR and PRP/HSR Redundancy Box, RSTP, MRP and Fast MRP ensure a high level of network availability.

Mounted on DIN rails, the switches can easily be activated by plug and play and feature sturdy, compact stainless steel housings measuring 100W x 164H x 116D mm.

With its new RSP family of Hirschmann Ethernet switches Belden is expanding Ethernet to cover the field-level networks of electricity supply companies. At the same time the company is the world’s first manufacturer to offer switches with integrated PRP and HSR redundancy protocols.

As product manager Jürgen Schmid says: "A modern IT infrastructure not only offers manifold possibilities, it also involves a number of risks, from broken wires to hacker attacks. These new Hirschmann RSP switches give users maximum security and thus uninterrupted access to their applications’ data communications."
