GE Consumer & Industrial Multilin Multilink ML1600/2400 Ethernet Communications Switch Quick Start Guide Quick Start 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 to correctly configure the Multilink switch for typical protective relaying applications. For this discussion the range of IP addresses that will be used are within the range of 3.94.247.1 to 3.94.247.254 using a subnet

QUICK START GUIDE Twisted Pair copper cable • Easy to Terminate • Low installation costs • Susceptible to noise interference • Limited by 100m distance • 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 MULTILINK ML1600/2400 ETHERNET COMMUNICATIONS SWITCH – QUICKSTART GUIDE

QUICK START GUIDE QS.1.2 Supported Network Topologies With either 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 of several switches higher speed uplink ports is often referred to as a backbone. Star Ring Mesh Star Architecture • Single Point of failure before loss of comm

QUICK START GUIDE QS.2 10BASE T and 100BaseT Media 10 Base T and 100 Base T 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 100 Base T, the 10 or 100 designation indicates a baud rate of either 10 or 100 megabits per second. Base stands for baseband while the T stands for "twisted pair." Since many twisted pair interfaces can work at either baud rate, the desi

QUICK START 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 a "patch" cable. Whether the cable is straight-through or crossover as per standard* each of the wires within the cable has the f

QUICK START GUIDE QS.3 Hubs and Switches Two of the major Ethernet LAN components are "hubs" and "switches." There are many advantages of a switch over a hub. Hubs just transfer information from one port to all other ports. Since a hub has no way of handling media contention, collisions can occur requiring all segments connected to a hub to work in a half duplex mode. Switches on the other hand have the capability of buffering messages allowing full duplex operation. A switch will also learn the

The outer clad of both is 125 micrometers in diameter. The multi-mode core, at 62.5 micrometers, is a little bit thinner than the average huma

QUICK START GUIDE micrometer fiber is 8 microns in diameter (almost an eighth of that of the Multi-Mode fiber) surrounded by a second outer clad. This clad can pass a light signal, so for this reason the fiber is referred to as 9 by 125 micrometer fiber. FIGURE QS–3: Differences between Multi-Mode and Single-Mode Cable Single mode fiber - Less attenuation per unit distance The difference between multi-mode and single mode cable can be best described as follows: With multi-mode fiber the index of

QUICK START GUIDE QS.4 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, but must be calculated as follows: • First the "Optical Power Budget" is determined by subtracting the receiver’s rated sensitivity from the transmitter’s rated power, both of which are defined in decibels of light intensity. For example if a particular transmitter is rated at minus15 db and

Once you have obtained a cable with this pin configuration, connect one end to the computer’s serial port and the other to the Multilink switch port.

QUICK START GUIDE In this example the switch that the computer is connected to is a Multilink ML1600. The instruction manual for the MultiLink provides a list of all instructions. A valid IP address and subnet mask can be programmed into the switch using the IP config command as follows: Type ipconfig ip=, then enter the IP address (in our example we will use a unique address between 3.94.244.1 and 3.94.244.254), followed by a space.
