Chapter 1: Introduction Overview These switches are high-performance Gigabit Ethernet switches designed for delivering Gigabit connectivity to the desktop. They provide 16/24 full-duplex 1000BASE-T ports that significantly improve network performance and boost throughput for high-bandwidth applications. With 32/48 Gigabits of aggregate bandwidth, these switches provide the quickest solution to meeting the growing demands on your network's limited resources.
1 Introduction Switch Architecture These switches employ a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. These switches also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. These switches use store-and-forward switching to ensure maximum data integrity.

1 Introduction Features and Benefits Connectivity • 16/24 10/100/1000BASE-T RJ-45 ports. • Auto-negotiation enables each RJ-45 port to automatically select the optimum speed (10, 100, or 1000 Mbps), and the communication mode (half or full duplex) if this feature is supported by the attached device. • Independent RJ-45 10/100/1000BASE-T ports with auto MDI/MDI-X pinout selection.
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 has, therefore, been recognized as one of the most important building blocks for today’s networking technology.
2 Network Planning Application Examples These switches are 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 in the following pages. Collapsed Backbone These switches are an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future.
Application Examples 2 Network Aggregation Plan With 16 or 24 parallel bridging ports (i.e., 16 or 24 distinct collision domains), the switch can collapse a small network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the ports on the switch are providing 100 Mbps connectivity through layer 2 switches. In addition, the switch is also connecting several servers at 1000 Mbps. Figure 2-2.
2 Network Planning Application Note 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.
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, 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.
Mounting 3 Mounting The switch units 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-2.
3 2. Installing the Switch Mount the device in the rack, using four rack-mounting screws (not provided). 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. Desktop or Shelf Mounting 1. Attach the four adhesive feet to the bottom of the first switch. Figure 3-4. Attaching the Adhesive Feet 2.
Connecting to a Power Source 3 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. Figure 3-5. Power Socket 2. Plug the other end of the cable into a grounded, 3-pin socket. 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 These switches 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. Twisted-Pair Devices Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends.
4 2. Making Network Connections 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. Otherwise, attach the other end to an available port on the switch. Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length. 3. As each connection is made, the Link LED (on the switch) corresponding to each port will light to indicate that the connection is valid.
Connectivity Rules 4 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 • Power supply is disconnected. • Check connections between the switch, the power cord, and the wall outlet. • Contact your dealer for assistance. 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.

Appendix B: Cables Twisted-Pair Cable and Pin Assignments For 10/100BASE-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.

This cable testing information is specified in the ANSI/TIA/EIA-TSB-67 standard. Additionally, cables must also pass test parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT).
