Chapter 1 Introduction

Congratulations on your purchase of the NETGEAR Model FS518 Fast Ethernet Switch. This switch provides you with a low-cost, high-performance network solution and is designed to support power workgroups operating at either 10 megabits per second (Mbps) or 100 Mbps. To relieve server and backbone bottlenecks, the Model FS518 switch also has two Gigabit Ethernet ber uplink ports.
Benets of Using Switching Technology
A majority of installed networks today are based on shared network technology. With this technology, a number of users or groups of users share a total available network bandwidth (or network capacity) of 10 Mbps, 100 Mbps, or other amounts of network bandwidth. For example, with a total of 10 users, the average bandwidth available to each user on a 10 Mbps network is calculated as 10/10 Mbps, which equals 1 Mbps of bandwidth per user. On a 100 Mbps (Fast Ethernet) network, the average bandwidth available to each of the 10 users is 100/10 Mbps, which equals 10 Mbps of bandwidth per user. Ethernet switches signicantly increase network throughput by segmenting network trafc. They check trafc coming in to each port to learn which network device is located on which segment. Based on this information, switches forward cross-segment trafc only to the appropriate segment. The trafc will not show up in the other segments because it is ltered out. In this way, network capacity is fully reserved for trafc destined for that segment only, and other segments will not be saturated with unnecessary trafc. Ethernet switches provide private, dedicated, 10 Mbps (or 100 Mbps) capacity to each connected PC/server or hub/workgroup segment, which is signicantly higher than in a shared environment. The higher bandwidth enables the use of applications such as multimedia, imaging, video, or high-performance client-server functions among users who are spread out over the network.

Introduction

Installation Guide for the Model FS518 Fast Ethernet Switch
This improvement is accomplished very easily, with no change to the desktop (the network interface cards or software and the network wiring). As a result, the performance upgrade and the applications it enables are obtained very quickly and at a low cost. When all network ports are operating at 100 Mbps and sending trafc to the server, the server needs a faster transmission speed to avoid bottlenecks. The 1000 Mbps (Gigabit) ports add the necessary increase in throughput.
Types of Ethernet Switches
Ethernet switches can be classied in different waysas desktop switches or as segment switches. A desktop switch is designed to support one or a few PCs per port. It is generally used when the individuals need the full 10 Mbps network throughput to support the applications. Often, these switches support only a single MAC (media access control) address per port, have high-speed 100 Mbps ports to connect to fast servers, and are relatively inexpensive compared to a segment switch. A segment switch, in contrast, is designed to support an entire workgroup on each port, with each port having signicant memory buffering and supporting thousands of MAC addresses. Switches can also be classied by speed. As the name suggests, 10 Mbps switches support only 10 Mbps connections. Similarly, 100 Mbps switches support only 100 Mbps connections. Usually, 10/100 Mbps switches have primarily 10 Mbps ports with only one or a few 100 Mbps ports. Autosensing 10/100 Mbps switches support 10 Mbps or 100 Mbps connections on each port and are the most versatile and adaptive type of switches. Gigabit (1000 Mbps) switch ports are used to connect to shared network resources and network backbones at higher speed.

Model FS518 Switch Overview
The NETGEAR Model FS518 Fast Ethernet Switch with Gigabit uplinks is an autosensing 10/ 100 Mbps switch with two Gigabit uplink interfaces. This high-performance switch is developed primarily to be used as a segment switch, even though it is priced as a desktop switch. All of the UTP ports on the Model FS518 switch can adapt automatically to the speed of the connected network or the PC, and the ports can operate at either 10 Mbps or 100 Mbps. In addition, each port can automatically negotiate with the connected device to operate in full-duplex mode. If the connected device is operating in half-duplex mode only or does not have the capability to participate in the negotiation process, the port will default to half-duplex mode. The Model FS518 switch can be used to partition a 10 Mbps or 100 Mbps network to enhance the capacity of the network to support advanced applications. In addition, the switch provides a link between traditional 10 Mbps networks and faster 100 Mbps networks. By installing a Model FS518 switch, a user can connect any 10 Mbps or 100 Mbps device to the switch without worrying about the running speed of the device. The Model FS518 switch provides a built-in upgrade path; you can remove a 10 Mbps connection and replace the connection with a 100 Mbps connection with little or no change to the rest of the network. The Model FS518 switch can be effectively used to join multiple 100 Mbps Fast Ethernet segments and to extend the reach of the network. Copper-based Fast Ethernet networks have a network diameter of up to 200 meters. The Model FS518 switch can be used to join these 200-meter segments to enable them to function as a single logical network. With one Model FS518 switch, the reach extends to 400 meters. The Gigabit Ethernet uplink ports on the Model FS518 switch can be used to connect to the network backbone and shared network resources such as servers at 1000 Mbps. The full-duplex 1000BASE-SX ports allow users to connect at high speed to a wiring closet or server located from 2 to 525 meters away. All 10/100 ports can autonegotiate the duplex mode with the connected device. If negotiation fails, the ports default to half-duplex mode. Gigabit ber ports will advertise their full-duplex operation and negotiate ow control with the connected device. If negotiation fails, the ports will default to full-duplex mode and no ow control. Because the Model FS518 switch is an ISO media access control (MAC) layer device, the switch is network protocol independent and compatible with all popular networks such as the Internet or TCP/IP, NetWare, DECnet, Microsoft NETBEUI, and LANTASTIC.

Features

The Model FS518 switch has the following key features: 16 autonegotiating (speed and duplex mode) 10/100 Mbps UTP ports to provide fast information exchange, resource sharing, and client or peer-to-peer communication using simple Category 5 unshielded twisted pair (UTP) cable 16 vista RJ-45 network ports with built-in LEDs to monitor individual port status Two autonegotiating (duplex mode and ow control) Gigabit ber ports with standard SC connectors The ports support multimode optical ber (SX) up to 525 meters (m) with 50 m ber cable. With 62.5 m ber cable, the maximum distance is 260 m. Two 62.5/125 m ber cables included for connecting the Gigabit ports to servers or the network backbone Autonegotiation supported by all 10/100 Mbps and Gigabit ports Automatic address-learning function to build the packet-forwarding information table The table contains up to 8,000 MAC addresses (that is, the switch can support networks with as many as 8,000 devices). Wire-speed ltering and forwarding to direct trafc to the appropriate route without slowing down the trafc Store-and-forward forwarding mode to minimize erroneous packets on the network Aging function to automatically track changes in network conguration Minimum latency of packet transmission (leading edge to leading edge) less than 80 s Easy plug-and-play installation with no software to congure, which saves time and minimizes the potential for conguration errors Protocol independence and compatibility with all common protocols such as TCP/IP, NetWare, DECnet, and Microsoft Networks Normal/Uplink push button to simplify network extension to 10/100 segments Connection to a hub using a simple, straight-through cable

RJ-45 Plug and Vista RJ-45 Connector
In a Fast Ethernet network, it is important that all 100BASE-T certied Category 5 cabling use RJ-45 plugs. The RJ-45 plug accepts 4-pair unshielded twisted pair (UTP) or shielded twisted pair (STP) 100 ohm cable and connects into the vista RJ-45 connector. The vista RJ-45 connector (also referred to as a 10/100 Mbps port) is used to connect stations, hubs, and switches through UTP cable; it supports 10 Mbps or 100 Mbps data transmission. The RJ-45 plug and vista RJ-45 connector are both illustrated in Figure B-1.

Duplex SC Plug and Duplex SC Connector
The duplex SC connector connects stations, hubs, and switches that support the 1000BASE-SX fiber interface. Each ber link needs a clearly dened, external crossover. In other words, the transmit port of one interface must be wired to the receive port of the opposite interface and vice versa. Fiber cables must be connected in this manner to transmit and receive data. The duplex SC connector and duplex SC plug are illustrated in Figure B-2.

Appendix C Cabling Guidelines
This appendix provides specications for cables used with the Model FS518 Fast Ethernet Switch.
Fast Ethernet Cable Guidelines
Fast Ethernet uses UTP cable, as specied in the IEEE 802.3u standard for 100BASE-TX. The specication requires Category 5 UTP cable consisting of either two-pair or four-pair twisted insulated copper conductors bound in a single plastic sheath. Category 5 cable is certied up to 100 MHz bandwidth. 100BASE-TX operation uses one pair of wires for transmission and the other pair for receiving and for collision detection. When installing Category 5 UTP cabling, use the following guidelines to ensure that your cables perform to the following specications: Certication Make sure that your Category 5 UTP cable has completed the Underwriters Laboratories (UL) or Electronic Testing Laboratories (ETL) certication process. Termination method To minimize crosstalk noise, maintain the twist ratio of the cable up to the point of termination; untwist at any RJ-45 plug or patch panel should not exceed 0.5 inch (1.5 cm).

Cabling Guidelines

Category 5 Cable
Category 5 distributed cable that meets ANSI/EIA/TIA-568-A building wiring standards can be a maximum of 328 feet (ft) or 100 meters (m) in length, divided as follows: 20 ft (6 m) between the hub and the patch panel (if used) 295 ft (90 m) from the wiring closet to the wall outlet 10 ft (3 m) from the wall outlet to the desktop device
The patch panel and other connecting hardware must meet the requirements for 100 Mbps operation (Category 5). Only 0.5 inch (1.5 cm) of untwist in the wire pair is allowed at any termination point.
Category 5 Cable Specications
Ensure that the ber cable is crossed over to guarantee link. Table C-1 lists the electrical requirements of Category 5 UTP cable.

Table C-1.

Twisted Pair Cables

For two devices to communicate, the transmitter of each device must be connected to the receiver of the other device. The crossover function is usually implemented internally as part of the circuitry in the device. Computers and workstation adapter cards are usually media-dependent interface ports, called MDI or uplink ports. Most repeaters and switch ports are congured as media-dependent interfaces with built-in crossover ports, called MDI-X or normal ports. Figure C-1 illustrates straight-through twisted pair cable.

Patch Panels and Cables

If you are using patch panels, make sure that they meet the 100BASE-TX requirements. NETGEAR recommends Category 5 UTP cable for all patch cables and work area cables to ensure that your UTP patch cable rating meets or exceeds the distribution cable rating. To wire patch panels, you need two Category 5 UTP cables with an RJ-45 plug at each end, as shown in Figure C-3.

Fiber Optic Cables

In North America, use EIA-569-A horizontal 62.5/125 m multimode optical ber cable (ANSI/EIA/TIA-492AAAA). Internationally, use ISO/IEC 11801 62.5/125 m multimode optical ber cable (IEC 793-2 type A1b, with 1.0 db/km attenuation and 500 MHz/km bandwidth). Refer to Table C-2 for the minimum requirements of ber optic cable.

Fast Ethernet Switches

FS509 FS518

N E T G E A R 's Fast Ethernet switches provide a cost-effective way to instantaneously increase network performance while preserving most of your network investment, including installed cabling and end users' software and hardware. Multiple 100 Mbps clients can access the server or backbone without creating a bottleneck thanks to Gigabit uplink ports (one in the FS508, and two in the FS518). At the same time, the switched 10/100 ports provide you with automatic speed and full/half-duplex sensing per port. Running in full-duplex mode, each port delivers 200 Mbps of network speed to keep your small business moving fast and effectively.

ACCESSIBLE

Eight or sixteen switched 10/100 Mbps ports provide dedicated 10 or 100 Mbps bandwidth for connecting multiple PCs, servers, and hubs.

EFFECTIVE

Each port supports up to 200 Mbps of throughput in full duplex mode.

INTUITIVE

These switches begin operating as soon as they are powered on. Every port automatically senses the proper speed and full/half duplex mode, taking the Help is there when you need it!
