Preface
This guide describes the RUGGEDCOM RS950G. It describes the major features of the
device, installation, commissioning and important technical specifications.
It is intended for use by network technical support personnel who are responsible
for the installation, commissioning and maintenance of the device. It is also
recommended for use by network and system planners, system programmers, and
line technicians.
Cybersecurity information
Siemens provides products and solutions with industrial cybersecurity functions that
support the secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats,
it is necessary to implement – and continuously maintain – a holistic, state-of-the-
art industrial cybersecurity concept. Siemens' products and solutions constitute one
element of such a concept.
Customers are responsible for preventing unauthorized access to their plants,
systems, machines and networks. Such systems, machines and components should
only be connected to an enterprise network or the internet if and to the extent
such a connection is necessary and only when appropriate security measures (e.g.
firewalls and/or network segmentation) are in place.
For additional information on industrial cybersecurity measures that may be
implemented, please visit https://www.siemens.com/cybersecurity-industry.
Siemens' products and solutions undergo continuous development to make them
more secure. Siemens strongly recommends that product updates are applied as
soon as they are available and that the latest product versions are used. Use of
product versions that are no longer supported, and failure to apply the latest updates
may increase customer's exposure to cyber threats.
To stay informed about product updates, subscribe to the Siemens Industrial
Cybersecurity RSS Feed under https://www.siemens.com/cert.

1.3 Decommissioning and disposal
Proper decommissioning and disposal of this device is important to prevent malicious
users from obtaining proprietary information and to protect the environment.
Decommissioning
This device may include sensitive, proprietary data. Before taking the device out of
service, either permanently or for maintenance by a third-party, make sure it has
been fully decommissioned.
For more information, refer to the associated "RUGGEDCOM ROS Configuration
Manual".
Recycling and disposal
This device is low in pollutants, can be recycled, and meets the requirements of the
WEEE directive 2012/19/EU for the disposal of electrical and electronic equipment.
RUGGEDCOM RS950G
Equipment Manual, 10/2023, C79000-G8976-1037-08 3

Introduction
1.4Cabling Recommendations
Do not dispose of devices at public disposal sites.
For environmentally friendly recycling and the disposal of devices, contact a certified
disposal company for electronic scrap or your Siemens contact.
For more information, refer to https://support.industry.siemens.com/cs/ww/en/
view/109479891.
Note the different national regulations.
1.4 Cabling Recommendations
All copper Ethernet ports on RUGGEDCOM products include transient suppression
circuitry to protect against damage from electrical transients and conform with
IEC 61850-3 and IEEE 1613 Class 1 standards. This means that during a transient
electrical event, communications errors or interruptions may occur, but recovery is
automatic.
Siemens does not recommend using copper Ethernet ports to interface with devices
in the field across distances that could produce high levels of ground potential rise
(i.e. greater than 2500 V), during line-to-ground fault conditions.
1.5 High Availability Seamless Ring Operation
Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR)
are two mechanisms defined by the IEC 62439-3 standard to provide hitless network
recovery. Unlike Spanning Tree Protocol (STP), which requires reconfiguration of the
active network topology over redundant physical links, HSR and PRP provide hitless
network recovery through the use of information replication.

Equipment Manual, 10/2023, C79000-G8976-1037-08

Introduction
1.5.1Parallel Redundancy Protocol
1.5.1 Parallel Redundancy Protocol
Parallel Redundancy Protocol (PRP) provides hitless network recovery by replicating
information over two physically independent Ethernet networks. The following
illustrates a typical PRP network:

Figure1.3 PRP Network Design
Note
PRP expands the Ethernet frame by 6 octets due to RCT (Redundancy Check Trailer).
Generation of PRP supervision frames also consumes bandwidth. As a result, the
network designer should keep in mind the overhead introduced by the PRP network
when calculating the network capacity.

Introduction
1.5.2High Availability Seamless Redundancy
1.5.2 High Availability Seamless Redundancy
The basic principle behind High-availability Seamless Redundancy (HSR) is the
replication of frames over both sides of the HRS ring. The following illustrates a
typical HSR network:

5 Receiving IED
Figure1.4 HSR Network Design
All of the network nodes inside an HSR ring must be HSR-capable. HSR-unaware
nodes can be attached to the HSR ring through the use of a RedBox (Redundancy
Box). Compared to PRP, HSR only demands approximately half of the network
infrastructure. However, network bandwidth on an HSR ring is approximately halved
compared with a network ring based on RSTP technology.
Note
Current HSR implementation limits link utilization to 74% when using multicast
traffic.

2.3Mounting the Device
Note
If any item is missing or damaged, contact Siemens for assistance.
2.3 Mounting the Device
The RUGGEDCOM RS950G is designed for maximum mounting and display flexibility.
It can be equipped with connectors that allow it to be installed in a 35 mm (1.4 in)
DIN rail or directly on a panel.
Note
For detailed dimensions of the device with either DIN rail or panel hardware installed,
refer to "Dimension Drawings" (Page 25).
2.3.1 Mounting the Device on a DIN Rail
For DIN rail installations, the RUGGEDCOM RS950G can be ordered with a DIN rail
mounting bracket pre-installed on the rear of the chassis. The bracket allow the
device to be slid onto a standard 35 mm (1.4 in) DIN rail.
NOTICE
DIN rail mounting is not recommended for constant vibration environments.
To mount the device to a DIN rail, do the following:
1. Pull the DIN rail adapter down and clip the device on to the DIN rail. Release the

Installing the Device
2.4Connecting the Failsafe Alarm Relay
2.4 Connecting the Failsafe Alarm Relay
The failsafe relay can be configured to latch based on alarm conditions. The NO
(Normally Open) contact is closed when the unit is powered and there are no active
alarms. If the device is not powered or if an active alarm is configured, the relay
opens the NO contact and closes the NC (Normally Closed) contact.
Note
Control of the failsafe relay output is configurable through RUGGEDCOM RS950G.
One common application for this relay is to signal an alarm if a power failure occurs.
For more information, refer to the "RUGGEDCOM RS950G User Guide" for the
RUGGEDCOM RS950G.
The following shows the proper relay connections.

supply
NOTICE
• For 110/230 VAC rated equipment, an appropriately rated AC circuit breaker
must be installed.
• For 125/250 VDC rated equipment, an appropriately rated DC circuit breaker
must be installed.
• Use minimum #16 gage wiring when connecting terminal blocks.
• Equipment must be installed according to applicable local wiring codes and
