Siemens Ruggedcom RMM2972-2RNA

$1.00

Siemens has introduced a new line module for the Ruggedcom RST2228 and RST2228P Layer 2 19” rack switches, the Ruggedcom RMM2972-2RNA.

This module adds further value to the Ruggedcom RST2228 19” rack switches by providing seamless redundancy with PRP/HSR (Parallel Redundancy Protocol/High-availability Seamless Redundancy), enhanced IEEE1588 implementation, high bandwidth uplinks, and traffic filtering and segmentation from a single device.

Description


Ideal for high port density applications in the electric power, transportation, oil & gas, and other industries.

This module eliminates network downtime due to single point(s) of fault, resulting in high reliability and availability for modern digital substation applications as mandated by the IEC 61850 standard. The RMM2972-2RNA module plugs into either slot 1 or slot 2 of the RST2228 device and allows it to participate in PRP/HSR networks that deliver 0 ms recovery time and zero packet loss. Its interfaces include PRP/HSR ports A & B supporting speeds of up to 1000 Mbit/s.

Ruggedcom RST2228 with the RMM2972-2RNA functions as a PRP/HSR Redundancy Box (RedBox) that can support up to 24 legacy SAN (Singly Attached Nodes) devices.

With two such modules, it can function as a QuadBox. It also supports coupling between different redundant topologies.

Any industrial network with pre-existing Ruggedcom RST2228 switches using MRP or RSTP protocols can now be migrated to the HSR protocol.

Multiple redundant configurations supported by this module allow for a simpler network design with fewer devices, lower operating costs and significantly improve overall network performance.

The utility-grade design of this module means it can operate between -40 to +85 °C and can withstand high levels of electromagnetic and radio frequency interference, making it an essential network component for mission critical networks in harsh environments, especially as those seen in electric power utilities.

Proven Reliability:

When it comes to RUGGEDCOM products: Siemens conducts Highly Accelerated Life Testing (HALT) in the early stages of product development to detect any design or performance issues as well as Highly Accelerated Stress Screening (HASS) later to ensure that customers get orders free of manufacturing errors and random defects. RUGGEDCOM products are thus able to provide reliable and error-free operation in harsh industrial environments.

 

High immunity:

The proliferation of IP networking technology in real-time, mission critical control applications requires a level of immunity to electromagnetic interference (EMI) beyond what is currently delivered by commercial grade networking products. Technology used in RUGGEDCOM products is able to withstand all EMI type tests required by IEC 61850-3 without any communications loss or delays. Products with this technology also qualify as IEEE 1613 class 2 error-free devices. This innovation – known as Zero Packet Loss™ technology – is designed to provide the same level of EMI immunity as protective relaying devices.
