The NETGEAR™ Model FS516 16-Port Fast Ethe rnet Swi tch and Model FS524
24-Port Fast Ethernet Switch provide you with a low-cost, high-performance
network solution and are designed to support power workgroups operating at
either 10 megabits per second (Mbps) or 100 Mbps.
Ethernet switches provide private, dedicated, 10 Mbps (or 100 Mbps) capacity
to each connected PC/server or hub/workgroup segment, which is significantly
higher than in a shared environment. The higher bandwidth enables the use of
applications such as multimedia, imaging, video, or high-performance clientserver functions among users who are spread out over the network.
With both the Model FS516 switch and the Model FS524 switch, improvement
is accomplished very easily, with no change to the desktop (the network
interface car ds or s oftw are an d th e netw ork wir ing). As a r esult , the pe rform ance
upgrade and the applications it enables are obtained very quickly and at a low
cost.
Features
The Model FS516 and Model FS524 switches have the following key features:
• Sixteen (Model FS516) or twenty-four (Model FS524) automatic speedsensing (autosensing) 10/100 Mbps Ethernet ports to provide fast
information exchange, resource sharing, and client or peer-to-peer
communication using simple Category 5 unshielded twisted pair (UTP)
cable
• Automatic address learning function to build the packetforwarding information table
The table contains up to 4,000 MAC addresses for the Model FS516 and
up to 8,000 MAC addresses for the Model FS524 (that is, the switch can
support networks with as many as 8,000 devices).
• Switch-selectable autonegotiating or full-duplex mode of operation
Full-duplex mode doubles throughput of point-to-point connections by
letting individual ports transmit and receive concurrently when the other
end also supports full-duplex mode. The default is half-duplex if the
connected device does not support N-way negotiation. The duplex toggle
switch can be set to full-duplex if the connected port is operating at fullduplex mode.
• Wire-speed filtering and forwarding to provide “traffic cop” function by
directing traffic to the appropriate route without slowing down the traffic
Store-and-forward forwarding node to minimize erroneous packets on the
network
• Half-duplex backpressure
• Easy Plug-and-Play installation with no software to configure, which saves
time and minimizes the potential for configuration errors
Model FS516/FS524 Fast Ethernet Switch Installation Guide
• Normal/Uplink push button to simplify network extension
The switch can be connected to a hub using a simple, straight-through
cable.
• Protocol independen ce and compatibi lity with al l common protocol s such as
TCP/IP, NetWare, DECnet, and Microsoft Networks
• Vista RJ-45 network ports with built-in LEDs to monitor individual port
status

The Normal/Uplink push button on the front panel of the switch allows you to
select uplink (MDI) or normal (MDI-X) wiring for port 16 on the Model FS516
switch and port 24 on the Model FS524 switch. These ports are configured for
normal wiring to connect to a PC when the push button is in the out position.
When the push button is pressed in, these ports are configured for uplink wiring
to connect to another switch or to a hub, using a straight-through twisted pair
cable.

FDX/AUTO Duplex Toggle Switches
Full-duplex mode is supported for all 10/100 Mbps ports and allows a port to
transmit and receive data at the same time. Full-duplex operation applies only to
point-to-point a cce ss (f or example, when a switch is connected to a PC, a se rver,
or another switch).
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 -duple x mode, de pend ing on the ope rati ng mode of
the remote port. If supported by the remote node, the port will establish a 100
Mbps full-duplex link as the default. If the remote port cannot provide the
proper signal to indicate its own capability, the 10/100 Mbps port on the switch
defaults to half-duplex mode. Because repeaters and hubs use a common
collision domain for all communi catio ns and cannot communicat e in fu ll-du ple x
mode, the associated 10/100 Mbps port on the switch should be set to autoduplex operation when connecting to these types of devices.
Setting the toggle switch to FDX on the 10/100 Mbps port enables the port to
determine the speed but will set the duplex mode to full-duplex.

Applications
The Model FS516/FS524 swi tch i s de si gned to provide f lexibility in con figuring
your network connections. Each switch can be used as a standalone device or
can be used with 10 Mbps or 100 Mbps hubs or other interconnection devices in
various configurations. The configuration examples in this section illustrate the
integration of t he switches in netw or k environmen ts of all sizes a nd types. These
examples include a network of a few workstations connected to a printer or a
segmented network with multiple users or workgroups and other networking
devices.
Desktop Switching
The Model FS516/FS524 switch is used as a desktop switch to build a small
network that enables users to have 100 Mbps access to a file server. If a fullduplex adapter card is installed in the server or PC, a 200 Mbps connection is
possible on the port where the server or PC is connected.

The Model FS516/FS524 switch is used to segment a network into multiple connected pieces,
increasing overall bandwidt h and through put. Both switch mode ls can segment networ ks that are
built with the NETGEAR Model DS508 and Mode l EN516 hubs and can function as bridges
connecting traditional 10BASE-T Ethernet networks to 100BASE-TX Fast Ethernet networks.

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. Most ports on
switches and repeaters have media-dependent interfaces with crossover ports.
These ports are referred to as MDI-X or normal ports. Computer and
workstation adapter cards are usually media-dependent interface ports referred
to as MDI or uplink ports.
These two figures illustrate the use of straight-through and crossover twisted
pair cables.
