GE Consumer & Industrial Multilin UR Switch Module Ethernet Communications Switch QuickStart Guide QuickStart Guide 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.
QUICKSTART GUIDE Twisted Pair copper cable • Easy to Terminate • Low installation costs • Susceptible to noise interference • Limited to 100m • Either shielded or unshielded (UTP) Fiber • Longer distances possible, limited only by attenuation • Immune to electrical noise • More difficult termination and splicing • Slightly higher cost for cable • Two categories: • multi-mode • single-mode QS–2 UR SWITCH MODULE – QUICKSTART GUIDE
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.
QUICKSTART GUIDE 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.
QUICKSTART GUIDE FIGURE QS–2: Pin Layout for RJ45 Ethernet Crossover (Patch) Cable The pin and wire configuration of a patch or crossover cable used to connect or establish a point-to-point Ethernet LAN between two Ethernet devices, is shown above.
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.
QUICKSTART GUIDE QS.3.2 Single and Multi-mode cable Fiber Cable Cross Section and Physical Specifications Multi Mode 125µm CORE 62.5µm CLAD • 62.5/125 µm • 50/125 µm* Single Mode 125 µm CORE 8 µm CLAD • 9/125 µm * Will become more popular as baud rate goes up 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.
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.
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).
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.

QUICKSTART GUIDE 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.
QUICKSTART GUIDE FIGURE QS–5: Traditional Redundant UR LAN Topology . FIGURE QS–6: Switch-enabled UR LAN Topology Note NOTE QS–14 • RSTP supports 16 switches in a Mess/Ring. • RO Mode supports a maximum of 18 switches in a ring. • With STP there is no limit.
QUICKSTART GUIDE QS.4.1 Hardware Overview The 2S and 2T managed Switch modules provide two 10/100 BaseT and four Multi-mode ST 100 base Fx external Ethernet ports in addition to a serial console port.

QUICKSTART GUIDE Z Select Save and after a short delay you should get a confirmation that the switch has been successfully configured. Once both the switch and UR’s IP address and Subnet Mask have been configured, power must be cycled to both the switch and relay.
QUICKSTART GUIDE QS.4.6 Assigning an IP Address to the UR Switch Module using the Console Port DB9 Female to DB9 Female Cable Pin-out Pin 2 Pin 2 Pin 3 Pin 3 Pin 5 Pin 5 The Switch has been shipped with a default IP address of 192.168.1.2 and a subnet mask of 255.255.255.0. Consult your network administrator to determine if the IP address, subnet mask or default gateway needs to be modified. In our example test network, the administrator has given us IP addresses ranging from 3.94.247.1 to 3.94.
QUICKSTART GUIDE The console port must be connected to the computer’s serial port using a serial cable with a pin-out as shown above. Note that both ends of the cable are terminated in a DB9 pin female connector. Pins 5 of this cable are connected together while pin 2 at one end is connected to pin 3 at the other end. Once you have connected the computer’s serial port to the switch’s console port, you can launch Hyperterminal as shown below.
QUICKSTART GUIDE Z Once the Hyperterminal application is launched you will need to cancel Hyperterminal’s dial sequence by left mouse clicking on the Cancel pushbutton. This will allow you to access Hyperterminal’s configuration menus. Z Select an icon and name to use for saving the new Hyperterminal configuration.
QUICKSTART GUIDE Z Select the computer’s serial port that is connected to the UR Switch. Z Select OK. Z In the next window set the baud rate to 38400, data bits to 8, no parity, one stop bit and set the flow control to none. Z Click on the OK icon to attempt communication to the UR Switch.
QUICKSTART GUIDE Z Press the Enter key until the message Hit to log into UR2S (or 2T) system is displayed. Z Press the Enter key one more time to get the Login prompt. Z Enter the login name manager and the default password manager. Once you are successfully logged in, the prompt will change to the model number of the Switch to which you are connected, followed by the pound (#) sign, indicating a successful login.
QUICKSTART GUIDE A valid IP address and subnet mask can now be programmed into the Switch using the IP config command as follows: Z Type in “ipconfig ip=“. Z Enter the IP address (in our example we will use a unique address between 3.94.247.1 and 3.94.247.254), followed by a space. Z Type in “mask=“ and enter the mask (in our example system we would use 255.255.252.0). Z If a default gateway is also required enter a space and type “dgw=“ Z Enter the IP address of the gateway, then select the enter key.
QUICKSTART GUIDE 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.
QUICKSTART GUIDE 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 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.

QS.4.8 Self-test Errors and Meaning Note NOTE Be sure to enable the Ethernet Switch Fail function under Product Setup > UserProgrammable Self-tests, and Port Events under Product Setup > Communications > Ethernet Switch.
QUICKSTART GUIDE No setting required; the UR will read the state of a general purpose I/O port on the main CPU upon power-up and create the error if there is a conflict between the I/O state and the order code. QS–32 EQUIPMENT MISMATCH: Card XXX Missing The UR has not detected the presence of the Ethernet Switch via the bus board. Relay failed to see Switch module on power-up, because Switch won’t power up or is still powering up. To clear fault, cycle power to the UR Relay.
QUICKSTART GUIDE 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.
QUICKSTART GUIDE QS.5.1 Configuring Tagged VLANs VLAN 1 VLAN 2 FIGURE QS–13: Tagged Virtual LANs Configuring a VLAN within the Switch To configure a VLAN within the switch: Z First determine which physical ports are to be part of the tagbased VLAN. Z Take note the names of the associated ports displayed on the home page. In our example we want the ports named A5 and A6 and A7 to be part of the new VLAN.
QUICKSTART GUIDE In this page we can see that the port named A5,A6 and A7 have been assigned port number 5, 6 and 7 respectively. . FIGURE QS–14: Associated Port Numbers; 7 is connected to the UR Z Now open the VLANs menu and select the Type menu. Z In this menu set the VLAN type to tag. Z Select the Save icon.
QUICKSTART GUIDE We have now configured the Switch to support Tag-based VLANs We can now proceed to the Tag-based VLAN menu .
