1. Product Overview
RuggedCom® RuggedSwitch™ 7 RS950G Installation Guide Rev 100
1. Product Overview
1.1. Functional Overview
The RuggedCom RS950G provides the ultimate in network reliability with Zero-Packet-Loss™
and zero failover time from any network fault. The RS950G supports IEC 62439, High Availability
Seamless Ring (HSR), which is the only Ethernet ring redundancy protocol that truly supporting
“bumpless” failover operation. The RS950G provides complete path redundancy by transmitting
duplicate packets on independent routes through the network. Receiving nodes eliminate any
redundant packets, resulting in a truly seamless failover mechanism not compromised by switch,
cable, or transient failure. The RS950G also provides inter-ring connectivity, allowing scalability
beyond a single ring and providing designers the freedom to create more complex networks.
The RS950G supports the IEEE 1588 v2 Precision Timing Protocol and provides 1µs accuracy
for demanding automation applications, such as IEC 61850-9-2 process bus and motion control.
IEC 61850-3 and IEEE 1613 electric utility substation certifications guarantee that the RS950G
is robust enough to provide uninterrupted operation in the harshest of environments. The
RS950G delivers unprecedented reliability, immunity, and performance for the most mission-
critical automation networks where a single lost message can affect operation. The RS950G is
ideal for implementation in utility networks as part of the Smart Grid solution.

1.1.2. IEC 62439 - High Reliability Applications
1.1.2.1. High Availability Seamless Ring (HSR) Operation
Figure 1.1. Typical HSR Ring Application
When the Sending Node communicates, the RS950G sends duplicate packets onto the network in
opposite directions. Using “cut-through” switching, packets are moved through the HSR network
to the receiving node with minimal latency. The receiving node removes duplicate packets from
the network. This example shows the use of both RS950G devices and the RuggedNet™ OEM
module.

RuggedCom® RuggedSwitch™ 10 RS950G Installation Guide Rev 100
1.1.2.2. HSR Inter-Ring Communication
Figure 1.2. Typical HSR Inter-Ring Application
Unlike other Ethernet ring protocols, HSR is not limited to single ring architecture. In “Quadbox”
mode, multiple inter-ring communications can be set up to increase the scale of the network and
maintain complete redundancy. This example shows the use of both RS950G devices and the
RuggedNet™ OEM module.

1.1.2.3. HSR with 1588 v2 Timing
Figure 1.3. IEEE 1588 Timing in an HSR Application
Both reliability and precision timing are critical in High Availability Networks controlling process
automation. The RS950G with IEEE 1588 v2 transparent clock is capable of 1µs accuracy.
Multicast IEEE 1588 v2 timing packets are handled with high priority to ensure accuracy and
eliminate timing jitter. This example shows the use of both RS950G devices and the RuggedNet™
OEM module.

(PRP)
Figure 1.4. HSR with PRP Application
For High Availability Networks requiring redundant, parallel physical and layer 2 hardware, use
the RS950G and RuggedNet™ devices in Parallel Redudancy Protocol (PRP) mode. Similar to
HSR, duplicate packets are generated by the sending node and are removed by the receiving
node. Note that PRP allows the use of singly attached on the network. This example shows the
use of both RS950G devices and the RuggedNet™ OEM module.

transient suppression circuitry internal to the unit.
4. Chassis Ground must be connected to the AC ground terminal.
1. Equipment must be installed according to the applicable country wiring codes.
2. All line-to-ground transient energy is shunted to the Surge Ground terminal. In
cases where users require the inputs to be isolated from ground, remove the
ground braid between Surge and Chassis Ground. Note that all line-to-ground
transient protection circuitry will be disabled.
2. Installation
RuggedCom® RuggedSwitch™ 17 RS950G Installation Guide Rev 100
2.3.2. DC Power Supply Wiring and Grounding
Figure 2.4. DC Power Supply Wiring and Grounding
The low voltage DC power supply features reverse polarity protection and dual independent inputs.
The latter feature allows the connection of two DC sources with the same nominal voltage to
provide redundant power supply inputs.
The DC power supply inputs should be connected as follows:
1. Connect to the DC inputs according to the polarity markings on the unit.
2. Surge Ground should be connected to the Chassis Ground via a braided cable or other
appropriate grounding wire. Surge Ground is used as the ground conductor for all surge and
transient suppression circuitry internal to the unit.
3. Chassis Ground must be connected to the protective earth.
1. Equipment must be installed according to the applicable country wiring codes.
2. All line-to-ground transient energy is shunted to the Surge Ground terminal. In
cases where users require the inputs to be isolated from ground, remove the
ground braid between Surge and Chassis Ground. Note that all line-to-ground
transient protection circuitry will be disabled.
2.3.3. Failsafe Output Wiring
The Failsafe output relay is provided to signal critical error conditions that may occur on the
unit. The contacts are energized upon power up of the unit and remain energized until an alarm
condition or power loss occurs.

2. Installation
RuggedCom® RuggedSwitch™ 18 RS950G Installation Guide Rev 100
2.3.4. Dielectric Strength Testing
Units which are to have dielectric strength testing (HIPOT testing) done in the field must have the
braided ground cable disconnected during the test. This is required in order to prevent the surge
suppression circuitry, which is connected to surge ground, from being activated.
Figure 2.6. Dielectric Strength Testing
2.4. Console Port Wiring
The RS232 port is used for configuring the unit. A straight-through serial cable with a DB-9
connector is required. There is no need to crossover the Transmit and Receive signals from the
PC side since this has been done internally.

3. Ports
3.1. Copper Ports
The RS950G features 10/100/1000TX ports for connection to standard Category 5 (CAT-5)
unshielded twisted-pair (UTP) cable with RJ45 male connectors. The RJ45 receptacles are directly
connected to the chassis ground on the unit and can accept CAT-5 shielded twisted-pair (STP)
cables. If shielded cables are used, care must be taken to ensure the shielded cables do not form
a ground loop via the shield wire and the RJ45 receptacles at either end.
The RS950G automatically disables the copper port when an SFP transciever is
installed in the corresponding fiber port.

3.1.1. Transient Protection
RuggedCom does not recommend the use of copper cabling of any length for critical real-time
substation automation applications. However, transient suppression circuitry is present on all
copper ports to protect against damage from electrical transients and to ensure IEC 61850-3 and
IEEE 1613 Class 1 conformance. This means that during the transient event communications
errors or interruptions may occur but recovery is automatic.
RuggedCom also does not recommended to use these ports to interface to field devices across
distances which could produce high levels of ground potential rise, (i.e. greater than 2500V) during
line to ground fault conditions.
RuggedCom requires the use of external surge protection in VDSL applications where the line may
be subject to surges greater than that for which the device is rated. Use the following specifications
as a guide for VDSL external surge protection:
• Clamping Voltage: 50V to 200V
• Insertion Loss: < 0.1 dB at 10 MHz
• Peak Surge Current: 10 kA, 8x20µs waveform
3. Ports

3.2. Fiber Optic Ports
The RS950G features optional small form-factor pluggable (SFP), fiber optic, 100FX or 1000LX,
transceiver ports. The RS950G supports the use of LC connectors in the SFP ports. The Transmit
(Tx) and Receive (Rx) connections of each port must be properly connected and matched for
proper link and operation.
The RS950G automatically disables the copper port when an SFP transciever is
installed in the corresponding fiber port.
