Features

Hardware

The RUGGEDCOM RST2228 has been specifically

designed and certified for industrial applications

such as electric power, transportation systems and

oil&gas applications.

Power supply

? Integrated power supply

? Universal high-voltage range: 88-300 VDC / 85-264 VAC

Harsh environments

As with all RUGGEDCOM products, Highly Accelerated

Life Testing (HALT) has been used in the early stages

of product development – to detect any design or

performance issues.

? Temperature: -40° C to +85° C (fanless)

? Safety: CSA/UL 60950

? Vibration: IEC 60255-21-1, Class 2

? Shock: IEC 60255-21-2, Class 2

? Humidity: IEC 60068-2-30, up to 95 relative humidity

Certifications

? IEC 61850-3 (electric substations)

? IEEE 1613 (electric substations)

? IEC 61000-6-2 (industrial environments)

Certifications in progress

? NEMA TS-2 (traffic control equipment)

? EN 50121-4 (railway applications)

Power-over-Ethernet (RUGGEDCOM RST2228P only)

The RUGGEDCOM RST2228P comes with up to 24

Power-over-Ethernet (PoE) interfaces supporting

IEEE 802.3at/802.3bt (draft with a shared power budget

from 500 Watt.) The individual ports have a maximum

of 60 Watt. For Power-over-Ethernet connections an

external power input is necessary.

Configuration interfaces

The RUGGEDCOM RST2228 is equipped with a USB

interface which enables easy in field configuration

and upgrading. The CLP interfaces allow for fast and simple

replacement devices in the field with the RUGGEDCOM CLP.

This helps to reduce downtimes when errors occur.

Software

The RUGGEDCOM RST2228 runs on Rugged Operating

System (ROS?) and delivers high performance switching.

ROS? supports the standard network technologies, such

as Rapid Spanning Tree Protocol (RSTP), Multiple Spanning

Tree Protocol (MSTP), Remote Monitoring (RMON), Simple

Network Management Protocol (SNMP) and others,

including proprietary protocol enhancements such as

Siemens eRSTP (enhanced Rapid Spanning Tree Protocol)

and Fast Root Failover (FRF).

Software features

? Quality of service (802.1p) for traffic prioritization

? NTP time synchronization (client and server)

? Smart power management for PoE interfaces

? Port rate and Broadcast Storm Limiting

? Port configuration, status, statistics, mirroring

? Simple Management interface through WebUI

and console interface

? Single file configuration ensures easy installation

and configuration control

Cyber security

Cyber security is an important issue in many industries

where advanced automation and communications

networks play a crucial role in mission critical applications

and where high reliability is of paramount importance.

Key RUGGEDCOM RST2228 features that address security

issues at the local area network level include:

? Passwords – support for multiple access levels with

separate credentials for each level

? SSH / SSL – extends capability of password protection

to add encryption of passwords and data as they cross

the network

? Enable / disable ports – capability to disable ports so

unauthorized devices can’t connect to unused ports

? SNMPv3 – encrypted authentication and access security

? HTTPS – for secure access to the web interface

? 802.1x – to ensure only permitted devices can connect

to the device

? MAC address authentication – control access to devices

that do not support RADIUS
