1 1-6 Introduction
Chapter 2: Network Planning Introduction to Switching A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. the switch have, therefore, been recognized as one of the most important building blocks for today’s networking technology.
2 Network Planning Application Examples The switch is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications are described below. Collapsed Backbone The switch is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future.
2 Application Examples Central Wiring Closet With 24 parallel bridging ports (i.e., 24 distinct collision domains), this switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 1000BASE-T RJ-45 ports on the switch are providing 1 Gbps full-duplex connections for up to 24 local segments. In addition, the switch is also connecting remote servers over fiber optic cable at 1 Gbps.
2 Network Planning Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a 1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-LH link up to 70 km. This allows a switch stack to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.
Application Examples 2 Making VLAN Connections The switch supports VLANs that can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment. VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs.
2 Network Planning Application Notes 1. Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. 2. For network applications that require routing between dissimilar network types, you can attach the switch directly to a multi-protocol router. 3.
Chapter 3: Installing the Switch Selecting a Site switch units can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to follow the guidelines below when choosing a location. • The site should: • be at the center of all the devices you want to link and near a power outlet.
3 Installing the Switch RJ-45 Connector Figure 3-1 RJ-45 Connections Equipment Checklist After unpacking the switch unit, check the contents to be sure you have received all the components. Then, before beginning the installation, be sure you have all other necessary installation equipment.
3 Mounting Mounting A switch unit can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. Mounting instructions for each type of site follow. Rack Mounting Before rack mounting the switch, pay particular attention to the following factors: • Temperature: Since the temperature within a rack assembly may be higher than the ambient room temperature, check that the rack-environment temperature is within the specified operating temperature range (see page C-1).
3 2. Installing the Switch Mount the device in the rack, using four rack-mounting screws (not provided). Be sure to secure the lower rack-mounting screws first to prevent the brackets being bent by the weight of the switch. 10 22 11 23 12 24 21 22 23 24 Figure 3-3 Installing the Switch in a Rack 3. If installing a single switch only, turn to “Connecting to a Power Source” at the end of this chapter. 4. If installing multiple switches, mount them in the rack, one below the other, in any order.
3 Installing an Optional SFP Transceiver 2. Set the device on a flat surface near an AC power source, making sure there are at least two inches of space on all sides for proper air flow. 3. If installing a single switch only, go to “Connecting to a Power Source” at the end of this chapter. 4. If installing multiple switches, attach four adhesive feet to each one. Place each device squarely on top of the one below, in any order.
3 Installing the Switch Connecting to a Power Source To connect a device to a power source: 1. Insert the power cable plug directly into the socket located at the back of the device. 100-240V ~50-60Hz 0.8A Figure 3-6 Power Socket 2. Plug the other end of the cable into a grounded, three-pin, AC power source. Note: For international use, you may need to change the AC line cord. You must use a line cord set that has been approved for the socket type in your country. 3.
Chapter 4: Making Network Connections Connecting Network Devices The switch units are designed to interconnect multiple segments (or collision domains). It can be connected to network cards in PCs and servers, as well as to hubs, switches or routers. It may also be connected to devices using optional SFP transceivers. Twisted-Pair Devices Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends.
4 Making Network Connections Connecting to PCs, Servers, Hubs and Switches 1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector. Figure 4-1 Making Twisted-Pair Connections 2. If the device is a PC card and the switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet. (See “Network Wiring Connections” on page 2.) Otherwise, attach the other end to an available port on the switch.
Twisted-Pair Devices 4 Network Wiring Connections Today, the punch-down block is an integral part of many of the newer equipment racks. It is actually part of the patch panel. Instructions for making connections in the wiring closet with this type of equipment follows. 1. Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel. 2.
4 Making Network Connections Fiber Optic SFP Devices An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX or 1000BASE-LH) can be used for a backbone connection between switches, or for connecting to a high-speed server. Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends. Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at both ends.
4 Fiber Optic SFP Devices 3. Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation. 8 9 9 10 11 12 20 21 22 23 24 21 22 23 24 Figure 4-3 Making Connections to SFP Transceivers 4. As a connection is made, check the Link LED on the switch corresponding to the port to be sure that the connection is valid.
4 Making Network Connections Connectivity Rules When adding hubs (repeaters) to your network, please follow the connectivity rules listed in the manuals for these products. However, note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.

4 Making Network Connections Cable Labeling and Connection Records When planning a network installation, it is essential to label the opposing ends of cables and to record where each cable is connected. Doing so will enable you to easily locate inter-connected devices, isolate faults and change your topology without need for unnecessary time consumption. To best manage the physical implementations of your network, follow these guidelines: • Clearly label the opposing ends of each cable.
Appendix A: Troubleshooting Diagnosing Switch Indicators Table A-1 Troubleshooting Chart Symptom Action Power LED is Off • Check connections between the switch, the power cord, and the wall outlet. • Contact your dealer for assistance. • Contact our Technical Support. Link LED is Off • Verify that the switch and attached device are powered on. • Be sure the cable is plugged into both the switch and corresponding device.
A Troubleshooting Installation Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly. In-Band Access You can access the management agent in the switch from anywhere within the attached network using a Web browser, or other network management software tools.
Appendix B: Cables Twisted-Pair Cable and Pin Assignments For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.
