QS.1 Introduction to Twisted Pair and Fiber Optic Ethernet
LANs
This section will provide a brief review of modern Ethernet media, before covering the steps
used to configure the Multilink switch for typical protective relaying applications. For this
discussion the IP addresses that will be used, are in the range of 3.94.247.1 to 3.94.247.254
using a subnet mask of 255.255.252.0. This same range of addresses can be used for
testing purposes but you should contact your IT support group for a valid range of
addresses to be used for your particular application.
QS.1.1 Ethernet Physical Layer: Twisted Pair Copper vs Fiber Optic
Today, the two most popular physical layer standards for Ethernet are twisted pair copper
cable and fiber optic cable. Twisted pair copper cable is easier to terminate, and has a
lower installation cost, but is susceptible to electrical noise. In addition, a single run of
twisted pair cable is distance-limited.
Fiber optic media can typically be applied over much longer distances, is immune to
electrical noise, and, while being more difficult to terminate, the availability of prefabricated cables has dramatically reduced the complexity of installation within the
substation.

QS–2 UR SWITCH MODULE – QUICKSTART GUIDE
QS.1.2 Supported Network Topologies
With both media, supported topologies include Star, Mesh, and Ring. The port that
connects one switch to another is often called the uplink port and with many switches the
uplink port can operate at much higher baud rates than the standard ports. The link
formed by the connection of several switches’ higher speed uplink ports is often referred to
as a backbone.

QUICKSTART GUIDE
QS.2 10BaseT and 100BaseT Media
10BaseT and 100BaseT are the two most common twisted pair copper media standards.
There are also several popular fiber optic media standards which we will review later in this
section. With respect to 10 or 100BaseT, the 10 or 100 designation indicates a baud rate of
either 10 or 100 megabits per second (Mbs). Base stands for baseband while the T stands
for twisted pair.
Since many twisted pair interfaces can work at either baud rate the designation 10/
100BaseT has evolved to indicate this capability. Cable can be either unshielded twisted
pair (UTP) or shielded twisted pair (STP).
We recommend category 5e (see below) for applications up to 1000 Mbs.
Unshielded Twisted Pair cable:
• Category 1: Used for telephone communications; not suitable for transmitting
data.
• Category 2: Capable of transmitting data at speeds of up to 4 Mbps.
• Category 3: Can be used in 10BaseT networks; can transmit data at speeds up to
10 Mbps.
• Category 4: Used in Token Ring networks; can transmit data at speeds up to 16
Mbps.
• Category 5: Capable of transmitting data at speeds up to 100 Mbps.
• Category 5e*: Used in networks running at speeds up to 1000 Mbps (1 Gbps).
• Category 6: Consists of four pairs of 24-gauge copper wires, which can transmit
data at speeds of up to 1000 Mbps.

FIGURE QS–1: Pin Layout for a RJ45 Ethernet Straight-through Cable
The cable itself consists of four pairs of wires terminated in RJ45 connectors. The
maximum permitted cable length is 100 meters. The cable pin connections can be one of
two configurations: the first is called a "straight-through" cable and the second is called
either a "crossover" or "patch" cable.
Given that the UR-2S/2T supports autonegotiate, a straight-through or crossover cable
may be used to connect or establish a point-to-point Ethernet LAN between two Ethernet
devices, as shown here.

QS–6 UR SWITCH MODULE – QUICKSTART GUIDE
QS.3 Hubs and Switches
Two of the major Ethernet network components are hubs and switches. A switch has
many advantages over a hub. Hubs simply transfer information from one port to all other
ports. Since a hub has no way of handling media contention, collisions can occur,
necessitating all segments connected to a hub to work in a half-duplex mode.
Switches on the other hand, are capable of buffering messages, thus allowing full duplex
operation. A switch will also learn the MAC addresses of devices connected to each of it’s
ports and will then route messages to only that port to which the destination device is
connected, thereby reducing data traffic on the network. Switches that use configuration
software to customize both switch and traffic are called “managed switches.” Other
switches - ones that have fixed configurations - are referred to as “unmanaged switches.”
QS.3.1 Fiber Optic Ethernet:
Fiber optic Ethernet is rapidly becoming the medium of choice in applications, such as
power system applications, where longer distances and immunity to EMI are of
importance. Having stated this, the higher cost and the difficulty of terminating fiber
cables allows twisted pair to continue to play a role were appropriate.
QUICKSTART GUIDE
The wavelengths of light used in fiber optic communication are 820, 1300 and 1550
nanometers (nm) because it has been found that these wavelengths are attenuated least
as they travel through the fiber optic medium. Compatible ports must operate at the same
light wavelength, and must be linked with appropriate fiber. There are two categories of
fiber optic cable: multi-mode and single-mode. Note that until recently, cable used with
820nm wavelength light was offered only in multi-mode, while cable used with 1300nm
wavelength light was offered with both single- and multi-mode compatibility. Cable
compatible with 1550nm wavelength light is offered only in single-mode.

The above are scaled drawings of both a 62.5/125 µm multi mode fiber and 9/125µm
single-mode fiber. The outer cladding of both is 125 micrometers in diameter. The multimode core, at 62.5 micrometers, is a little thinner than the average human hair. The core of
QS–8 UR SWITCH MODULE – QUICKSTART GUIDE
QUICKSTART GUIDE
the 9/125 micrometer fiber is 8 microns in diameter (almost an eighth of that of the multiMode fiber) surrounded by a second outer layer of cladding. This cladding can pass a light
signal, so for this reason the fiber is referred to as 9 by 125 micrometer fiber.
Difference between Single-mode and Multi-mode Cable
The difference between multi-mode and single mode cable can be best described as
follows:
With multi-mode fiber the index of refraction at the surface between the core and the
cladding is such that there is total internal reflection of the light being transmitted down
the core. Picture this by imagining that the clad is a tube whose interior surface is polished
so smooth, it is like a mirror. Light shinning at one end of the tube will either travel straight
down the tube or will travel down the tube by reflecting of the inner mirrored surface.
Single mode fiber can be described as an elongated lens that is continuously focusing the
light into the centre of the fiber. Using these two analogies it can be imagined that in the
single mode fiber more light travels through far less fiber medium resulting in far less
attenuation per unit distance than in multi-mode fiber. As a result, for a given wavelength
of light, single mode fiber typically has less attenuation per unit distance than multi-mode
fiber.
QS.3.3 Optical Power Budget
Inevitably the question that arises is, “What is the maximum practical communication
distance when using a fiber optic cable?”. The answer isn’t straightforward; it must be
calculated in the following way:
FIGURE QS–3: Differences between Multi-Mode and Single-Mode Cable
First the Optical Power Budget is determined by subtracting the receiver’s rated sensitivity
from the transmitter’s rated power, both of which are rated in decibels of light intensity. For
example, if a particular transmitter is rated at -15 db and the receiver’s sensitivity is rated
UR SWITCH MODULE – QUICKSTART GUIDE QS–9
QUICKSTART GUIDE
at -31 db the difference of 16 db is the Optical Power Budget. The Optical Power Budget
can be thought of as the maximum permitted attenuation of the light signal as it travels
from the transmitter to the receiver, while still permitting reliable communication.
The next step is to calculate the worst case optical power budget by subtracting from the
optical power budget, 1 dB for LED aging and 1 dB for each pair of connectors (referred to
as insertion loss).
The final step is to divide the calculated result by the rated cable loss per kilometer in order
to determine the maximum distance. For costly installations it is recommended to always
measure the actual cable loss before and immediately after installation, in order to verify
that the cable was installed correctly. To avoid damaging the receiver, ensure that the
maximum optical input power of the receiver isn’t exceeded.
FIGURE QS–4: Common Fiber Optic Connectors
Several styles of connector are used to terminate to, and attach the end of the fiber cable.
The ST and SC connectors are among the more popular. The UR Switch module supports 2
copper ports and 4 fiber ports (ST connectors).
QS–10 UR SWITCH MODULE – QUICKSTART GUIDE
QS.3.4 Maximum fiber segment length calculation:
The maximum fiber segment length between two adjacent switches or between a switch
and a device is calculated in the following way:
First, calculate the optical power budget (OPB) of each device using the manufactures data
sheets. Shown below are sample data sheets.
OPB = P
where:
OPB = Optical Power Budget
P
= transmitter output power
T
P
= receiver sensitivity
R
UR-2S and UR-2T fiber optic port specifications:
The worst case optical power budget (OPBWORST) is then calculated by taking the lower of
the power budgets for the two devices, calculated above, and subtracting 1 dB for LED
aging and then subtracting the total insertion loss. The total insertion loss is calculated by
multiplying the number of connectors in each single fiber path by 0.5 dB. For example, with
a single fiber cable between the two devices there would be a minimum of two
connections in either transmit or receive fiber paths for a total insertion loss of 1db for
either direction:
Total insertion loss = number of connectors x 0.5db
T(min)
- P
QUICKSTART GUIDE
R(min)
Total insertion loss = 2 x 0.5 dB = 1.0 dB.
Example: Assuming 62.9/125μm cable
Speed Mode λ Size P
100 Mb FX multi 1300 nm 62.5/125 μm
50/125 μm
-20 to -23.5 dB -31 dB
T
P
-31 dB
R
If we were calculating the worst-case optical power budget between two UR-2T or UR-2S
devices using a single fiber cable the result would be 7 dB:
OPB
OPB
OPB
= OPB - 1 dB (LED aging) - total insertion loss
WORST
= 10 dB - 1 dB - 1 dB
WORST
= 8 dB
WORST
To calculate the maximum fiber length, divide the worst-case optical power budget by the
cable attenuation per unit distance specified in the manufacturers data sheets. For
example a typical attenuation for 62.5/125 mm glass fiber optic cable is approximately
2.8dB per kilometer. If we were using a cable with this attenuation in our example the
maximum fiber length would be approximately 2.5 km.
Maximum fiber length = worst case OPB (in dB)/cable loss (in dB per km)
Maximum fiber length = 8 dB/2.8 dB/km= 2.8 km
Again, the customer must use the attenuation specified within the manufacturer’s data
sheets for accurate calculation of the maximum fiber length.

QS.4 Introduction to the 2S and 2T UR Managed Switch
Modules:
The UR-2S and UR-2T embedded managed Switch modules are supported in 9S CPU racks
with firmware ≥5.5x. The module communicates with the UR through an internal Ethernet
port, referred to as the "UR Port" or "Port 7," and provides the UR with six external Ethernet
ports: two 10/100BaseT and four Multi-mode ST 100 Base Fx ports. This greatly simplifies
the network configuration:
Note
The Ethernet Switch Module should be powered up before, or at the same time as, the UR
Relay. If not, the Switch Module will not be detected on power-up and the EQUIPMENT

Z Reboot the switch using the Reboot command as shown.
Note when asked to save the current configuration enter Y for Yes.
Z Once the Switch has rebooted, you will need to login again.
Z To confirm that the IP address and subnet mask were saved
correctly enter the command “show setup” followed by the Enter
key.
The Switch will then provide an on-screen list of the switch’s
settings including the switch’s IP address and subnet mask, and, if
programmed, the default gateway.
Once you have verified that the IP, subnet mask and default
gateway settings are correct you can configure the Switch via the

Z Press the Enter key.
If communication is working correctly you should get a response from the Switch. If there is
a problem you will get four consecutive timeout error messages. If this occurs check the
media, ensure that the IP address subnet mask has been set correctly, and try again.

Given that the UR-2S/2T supports Autonegotiation, a straight-through or crossover cable
may be used to directly connect a PC to the Switch.
NOTE
Z If the computer isn’t connected to the network you will require a
straight-through or a crossover cable and will need to set up a
static IP address to test.
QS.4.7 Assigning a static IP Address to a personnel computer
The Switch can be completely configured using the console port (after configuration of the
IP address and subnet mask, the Switch can be configured using the WEB interface).
In order to configure the Switch using the web-based interface, the computer must be
assigned an IP address and subnet mask. If the computer has already been assigned an IP
address or is connected to a network such that the IP address will be automatically
assigned, you may proceed to configure the Switch through the web Interface.
Z Obtain an IP address, subnet mask, and possibly a gateway
address from your LAN Administrator.
There are rules associated with the assignment of these numbers
which go well beyond this introduction. As mentioned at the
beginning of this guide, for our test network we will be using a
subnet mask of 255.255.252.0 for all computers and relays on the
network.
The IP address of each device on the network must be unique.
Given that the switch was already assigned the IP address
3.94.247.229, we are left with 253 unique addresses.

QS.5 Tagged VLAN’s
VLAN is short for virtual LAN. A VLAN creates separate network segments that can span
multiple switches. A VLAN is a group of ports designated by the switch as belonging to the
same broadcast domain. VLANs provide the capability of having multiple networks coexisting on the same switch. Separation of traffic and security are just two advantages of
VLANs.
VLANs can be port-based or tag-based. Port VLANs set a specific port or group of ports to
belong to a VLAN. When using tag-based VLANs, a tag - a "VLAN identifier" - is sent as part
of the message. This tag allows the message to move across multiple switches whose
ports are part of the same tagged VLAN. Note that the UR Port (Port 7), being the port
connected to the UR relay, must therefore be included in all VLANs from which the relay is
to receive or transmit data.
Background
The IEC 61850 Fixed GOOSE peer-to-peer communication service is an enhanced version
of IEC GSSE peer-to-peer service with the additional ability to assign a priority and a "tag"
to the multi-cast messages.
