Congratulations on your purchase of the NETGEAR Model SW510 10-port 10/100 Mbps Ethernet
Switch or the NETGEAR Model SW518 18-port 10/100 Mbps Ethernet Switch. These switches
are part of the NETGEAR™ 500-series product family. The switches allow simultaneous
transmission of multiple packets through an internal high-speed data channel, improving the
overall information throughput and productivity of a network environment.

Chapter 1

Introduction

Benefits of Using Switching Technology

Ethernet switches increase network throughput by segmenting network traffic. Instead of 10 PCs
all sharing a single 10 megabit per second (Mbps) network connection with an average of 1 Mbps
per PC, a 10-port switch provides the same 10 PCs with 10 Mbps individually. By using the
10-port switch, performance increases up to tenfold and is done with no change in network wiring,
adapters, or software. As a result, performance upgrade is obtained very quickly and at a low cost.

Overview of the Switches

The Model SW510 and Model SW518 switches can be utilized as either segment switches or
desktop switches. A
each port having significant memory buf fering and supporting hundreds of addresses (one or more
addresses per PC). A segment switch also provides significant performance benefits over a shared
hub. A
generally used where individuals within workgroups need 10 Mbps network throughput but also
require 100 Mbps access.

The design of the Model SW510 and Model SW518 switches enables the use of the devices in the
most demanding segment switching applications, yet pricing makes them very affordable for use
in desktop applications.

Installation Guide for the Model SW510 and Model SW518 Ethernet Switches

Increased bandwidth is another advantage of the Model SW510 and Model SW518 switches. In
addition to 10 Mbps ports, each switch has two Fast Ethernet ports that create a high-throughput
connection to a backbone or server with 100 Mbps transmission. In addition to partitioning an
overloaded network, the switches provide a link between traditional 10BASE-T and the faster
100BASE-TX networks. All ports on the switches can operate in either full-duplex or half-duplex
data transfer mode to support the interconnection requirements of other high-speed devices.

Up to nine switching paths (18 paths in full-duplex mode) can be established at the same time,
with each path crossing two ports, performing switching that sends packets to the appropriate port
according to the destination address scanned from the packet header. This technique reduces the
latency of packet transmission to 75 microseconds (µs) or less. Compared to approximately 800 µs
for a bridge or 1800 µs for a router, the Model SW510 and Model SW518 switches deli v er a major
improvement in the performance of your network.

Because the Model SW510 and Model SW518 switches are devices functioning on the media
access control (MAC) layer, they are protocol independent and are compatible with IEEE802.3,
IEEE802.3u, TCP/IP, NetWare, DECnet, and XNS protocols. Each of these switches can be
configured easily in most environments as a standalone device to form a workgroup consisting of
10 to 18 subnetworks or workstations, as a simple twisted-pair LAN, or as a multiport bridge. With
their low port-to-port latency and high forwarding efficiency, the Model SW510 and Model
SW518 switches can also be connected to other switching hubs.

The maximum distance between end nodes is not restricted as it was with the traditional repeaters.
Dividing your network into smaller and more manageable segments, each linked to the larger
network with a switch, creates a maximum distance for communications between end nodes that is
unlimited.

Features

The Model SW510 and Model SW518 switches have the following key features:

• Use in segment or desktop applications
Network productivity is improv ed by segmenting netw ork traf fic or providing pri v ate 10 Mbps

access to the desktop or server, with no changes to the software or network interface.

• Eight 10 Mbps unshielded twisted pair (UTP) Ethernet ports on the Model SW510 switch;
Sixteen 10 Mbps UTP Ethernet ports on the Model SW518 switch

One of the 10 Mbps UTP ports is configurable as Normal (MDI-X) or Uplink (MDI).

1-2 Introduction

In full-duplex mode, the throughput of point-to-point connections is doubled by enabling

individual ports to transmit and receive concurrently when the other end also supports
full-duplex mode.

• Auto- or full-duplex mode for the 10/100 Mbps ports:
— Auto-negotiable between full-duplex and half-duplex mode when set in auto-duplex mode

The mode will default to half-duplex transmission if the remote end cannot provide a
proper signal to indicate its own capability.

— Can be set to full-duplex mode permanently for interoperability with legacy 100B ASE-TX

devices

• Wire-speed filtering and forwarding to pro vide “traffic cop” function by directing traffic to the
appropriate route without slowing down the traffic

• Plug-and-Play operation with no software to configure

• Low latency store-and-forward transmission mode with leading edge to leading edge of less
than 75 µs

• Ten vista RJ-45 connector ports on the Model SW510 and eighteen vista RJ-45 connector
ports on the Model SW518 switch

Each port has built-in LEDs to monitor individual port status.

• Comprehensive LED indicator panel to monitor overall switching condition

• Auto address learning function to build the routing information database
The routing table contains 8,000 Ethernet address entries per port to store MAC addresses for

attached network nodes.

• 2-megabyte (MB) buffer provided for the 10 Mbps ports on the Model SW518 and 1 MB
buffer pro vided for the 10 Mbps ports on the Model SW510, with an additional 2 MB of buf fer
memory for the two 10/100 Mbps ports

• Conformity to the ISO/IEC 8802-3 and ANSI/IEEE 802.3 10BASE-T standards

• Conformity to the IEEE 802.3u 100BASE-TX standard

HDX/FDX/AUTO Duplex Toggle Switches

Full-duplex mode is supported for all 10 Mbps or 10/100 Mbps ports and allows the port to
transmit and receive data at the same time. Full-duplex operation applies only to point-to-point
access (for example, when a switch is connected to a PC, a server, or another switch). Because
repeaters and hubs use a common collision domain for all communications and cannot
communicate in a full-duplex mode, the associated 10 Mbps port on the switch should be set to
half-duplex operation when connecting to these types of devices.

Setting the toggle switch to AUTO on the 10/100 Mbps port enables the port to determine duplex
mode automatically. In this mode, the 10/100 Mbps port operates in either full- or half-duplex
mode, depending on the operating mode of the remote port. If the remote port cannot provide the
proper signal to indicate its own capability, the 10/100 Mbps port on the switch operates in
half-duplex mode.

As illustrated in Figure

2-4 and Figure 2-5, one half-duplex (HDX) and full-duplex (FDX) toggle

switch is assigned to each 10 Mbps port on a switch. On the Model SW510 switch, the 10 Mbps
ports are ports 1 through 8; on the Model SW518 switch, the 10 Mbps ports are ports 1 through 16.
The communication mode can be set to either half-duplex or full-duplex mode.

One FDX and AUTO toggle switch is assigned to each 10/100 Mbps port on a switch. On the
Model SW510 switch, the 10/100 Mbps ports are ports 9 and 10; on the Model SW518 switch, the
10/100 Mbps ports are ports 17 and 18.The communication mode can be set to either full-duplex
or auto-duplex mode.

This chapter presents an overview of the levels of service provided by incorporating the
technology of the NETGEAR Model SW510 and Model SW518 Ethernet switches into your
network. Examples are given to illustrate the role of the switch in several configurations that
provide those different levels of service to networks and users.

Chapter 3

Applications

The Model SW510 and Model SW518 switches are designed to provide flexibility in configuring
your network connections. The switch can be used as a standalone device or can be connected with
standard repeaters, switching hubs, or other interconnection devices in various configurations. The
configuration examples in this chapter illustrate the integration of the switch in network
environments of all sizes and types. These examples include a network of a few workstations
connected to a printer and a segmented network with multiple users and other networking devices.

Desktop Switching

The Model SW510 and Model SW518 switches are designed to perform the functions of a desktop
switch where a small group of users need to be assured of having 10 Mbps network access. A
power user on the same network can have a 100 Mbps connection to the switch and a 200 Mbps
connection to the server. Figure

Network Segmentation

Most networks are interconnected with two-port bridges that insert latency into normal
communications. For data that must pass through several bridges to reach its destination, this
latency can degrade communications. With several 10 Mbps bridging ports and the additional
internally bridged 100 Mbps port, the Model SW518 switch can segment a complex network into a
single efficient bridged node, increasing overall bandwidth and throughput. Segments attached to
the switching hub do not have to cross the backbone. They can now reach each other at near-zero
latency. For high-bandwidth applications that transfer data across the network backbone, the
100 Mbps port provides high-speed access.

The switch increases bandwidth for workgroups and strengthens network throughput when
accessing high-volume file servers. The Model SW518 switch provides parallel communication
between the high-speed 100 Mbps port and each of the 10 Mbps station ports. This method of
communication allows multiple conversations to occur concurrently. This method also expands
overall throughput and allows key servers or other heavily used devices to be available to more
users. Figure

For instructions on connecting to additional switches or other devices, refer to “

Connecting

Devices to the Switch.”

Connecting Devices to the Switch

To connect devices to the switch, follow these steps:

1. Connect the device to the selected ports on the switch and set the Normal/Uplink push

button appropriately.

The Normal/Uplink push button eliminates the need to use a crossover cable when connecting
similarly wired devices. Ports 8 and 10 on the Model SW510 switch and ports 16 and 18 on
the Model SW518 switch can be configured for normal (MDI-X) wiring or uplink (MDI)
wiring. Use the following guidelines to configure the ports:

• Set the Normal/Uplink push button to the Normal position and use a straight-through

cable if the remote end of the cable is connected to an MDI wired device such as a PC, a
server, or a router.

• Set the Normal/Uplink push button to the Uplink position and use a straight-through cable

if the remote end of the cable is connected to an MDI-X wired device such as a 10 Mbps
or 100 Mbps hub or repeater, or for backbone connection to another switch.

The ports without the Normal/Uplink push button are normal wired ports. If you are using one
of these ports to connect to another normal port as on a hub or repeater, a crosso ver cable must
be used to connect the two ports.

For further cabling guidelines, refer to Appendix C, “Cabling Specifications.”

4-4 Installation

SW510.bk Page 5 Wednesday, March 12, 1997 10:49 AM

Installation Guide for the Model SW510 and Model SW518 Ethernet Switches

2. Set the FDX, HDX, or AUTO toggle switches on the rear panel for the selected duplex

mode.

A hub and repeater use a common collision domain for all communications and cannot
support full-duplex mode. When connecting any of the 10 Mbps ports on the switch to a hub,
set the port to half-duplex mode. When connecting an y of the 10/100 Mbps ports on the switch
to a hub, set the port to AUTO. When connecting to a PC, a server, or another switch, the
duplex setting for the port must be the same as the duplex setting on the PC, server, or other
switch.

• To set the 10 Mbps ports (ports 1 through 8 on the Model SW510 switch and ports 1

through 16 on the Model SW518 switch):
— Move the toggle switch into the up position (to FDX) for full-duplex mode.
— Move the toggle switch into the down position (to HDX) for half-duplex mode.

• To set the 10/100 Mbps ports (ports 9 and 10 on the Model SW510 switch and ports 17

and 18 on the Model SW518 switch):
— Move the toggle switch into the up position (to FDX) for full-duplex mode.The duple x

switch must be set to FDX if you are connecting to legacy full-duplex 100 Mbps
devices that do not generate signals indicating duplex mode. If the duple x switch is set
to AUTO mode when connecting to legacy full-duplex 100 Mbps devices, the 10/100
Mbps ports will default to half-duplex mode because the port does not receive the
proper signal.

— Move the toggle switch into the down position (to AUTO) for auto-duplex mode. The

10/100 Mbps ports will negotiate and automatically determine the duplex mode based
on the mode of the connected port. If the connected port cannot auto-negotiate, the
10/100 Mbps port on the Model SW510 or Model SW518 switch will default to
half-duplex

mode.

Note: Whenever a port changes between FDX and HDX mode, the Model

SW510 and Model SW518 switches reset and traffic in all ports temporarily
stops. When the switches reset, the list of learned addresses is not affected.

3. Connect one end of the power cord to the power outlet on the back panel of the switch,

and connect the other end of the power cord to a wall receptacle.

The switch automatically selects the proper voltage in the range of 100 to 240 volts. The
Power LED lights, and the cooling fans start up after successfully completing the self-tests.
The switch is now operational.

Troubleshooting

LEDs

Verify that all other system components are functioning properly. There may be a defecti ve adapter
card, cable, or port. Check for defects and replace the defective component.

If the Link LED does not light up when a device is connected to its corresponding UTP port, check
that both the switch and the connected device are powered on. When connecting devices to the
switch with twisted pair cable, make sure that the cable length does not exceed 100 meters. Refer
to Chapter
information on twisted pair or straight-through cable use.

4, “Installation,” and Appendix C, “Ethernet and Cabling Guidelines,” for additional

HDX/FDX/AUTO Duplex Toggle Switches

The factory setting for the duplex toggle switches on the 10 Mbps ports is half-duplex (HDX)
mode, and the factory setting for the duplex toggle switches on the 10/100 Mbps ports is
auto-duplex (AUTO) mode.

If performance degradation is a problem or if file transfer is slow, make sure that the half- or
full-duplex setting of the NETGEAR switch and the connected device are the same. When
connecting the switch to a repeater or hub, the 10 Mbps port on the switch must be set to
half-duplex (HDX) mode and the 10/100 Mbps port must be set to auto-duplex (AUTO) mode.

For instructions on setting the duplex toggle switches, refer to “Connecting De

Installation

Verify that all system components have been properly installed. If one or more components are
malfunctioning, test them in an alternate environment where all other components are functioning
properly.

Cabling

To verify that the cabling is correct, refer to Appendix C, “Ethernet and Cabling Guidelines.” Be
sure all cable connectors are securely positioned in the required ports. Straight-through cables
should be used for all standard twisted pair connections.

Make sure all devices are connected to the network. Equipment may have been accidentally
disconnected.

Network Adapter Cards

Make sure the network adapter cards installed in the PCs are in working condition.

Configuration

If problems occur after altering the network configuration, restore the original connections and
determine the problem by implementing the new changes, one procedure at a time. Make sure that
cable distances, repeater limits, and other physical aspects of the installation do not exceed the
Ethernet limitations.

Switch Integrity

If required, verify the integrity of the switch by resetting the switch. Turn the power to the switch
off, and then turn the power to the switch back on. If the problem continues and you have
completed all the preceding diagnoses, contact your NETGEAR distributor.

Caution: Turning the power off and then turning the power on again will clear the

address table.

This appendix provides information about Ethernet technology and specifications for cables used
with the Model SW510 and Model SW518 Ethernet switches.

Appendix C

Ethernet and Cabling Guidelines

Ethernet Technology

When 10BASE-T technology was originally introduced, multiple repeaters were frequently used
to build large networks. To increase the number of connections, repeaters were connected together
because individual repeater port densities were often limited to 8 to 24 ports. As structured wiring
systems were implemented, horizontal wiring from the wiring closet to the desktop was designed
for a maximum distance of 100 meters. Stackable repeaters eliminated the need for collision
domains to extend over multiple repeater hubs.

The 100BASE-TX Fast Ethernet technology maintains the same concepts as the 10BASE-T
technology. Both use the same Carrier Sense Multiple Access with Collision Detection
(CSMA/CD) and Media Access Control (MAC) protocols. Both 10BASE-T and 100BASE-TX
Ethernet use the same type of Ethernet frame and error detection mechanisms. They also support
the same star topology using traditional media types and are manageable by the same network
management protocols. The most fundamental difference between the two technologies is that
100BASE-TX operates 10 times faster than traditional 10BASE-T.

The 100BASE-TX technology was developed to support the new paradigm and, by using
switching technology, can provide for the following four distinct levels of service:

• 10BASE-T dedicated bandwidth of 10 Mbps

• 100BASE-TX dedicated bandwidth that equals 100 Mbps

• 100BASE-TX shared bandwidth that equals 100 Mbps

• 10BASE-T shared bandwidth of 10 Mbps

Cable Specifications

Category 5 twisted pair cable must be used for 100 Mbps connections. For 10 Mbps connections,
Category 3, 4, or 5 cable can be used; however, NETGEAR highly recommends Category 5.
Category 5 cable will prevent unnecessary expenses or confusion if you upgrade to Fast Ethernet.

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. Some repeaters and switch ports are media-dependent interfaces with
crossover ports, referred to as MDI-X or Normal ports. Computer ports and PC adapter card ports
are usually media-dependent interface ports, referred to as MDI or Uplink ports. Refer to the
installation instructions in Chapter

4, “Installation,” for appropriate cable use and connection.
