Product Illustration
Front Panel
The front panel of the Model FS516/FS524 switch contains the following LEDs
that correspond to each network port located on the hub: Rx/Tx/Collision and
100 Mbps. Each vista RJ-45 network port has its own Link LED (located at the
top left corner of each 10/100 Mbps port), and full-duplex (FDX) LED (located
at the top right corner of each 10/100 Mbps port).

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 access (for example, when a switch is connected to a PC, a server,
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-duplex mode, depending on the operating 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 communications and cannot communicate in full-duplex
mode, the associated 10/100 Mbps port on the switch should be set to auto-
duplex 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 switch is designed to provide flexibility in configuring
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 the switches in network environments of all sizes and 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 full-
duplex 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.

Segment Switching and Bridging from 10 Mbps to 100 Mbps
The Model FS516/FS524 switch is used to segment a network into multiple connected pieces,
increasing overall bandwidth and throughput. Both switch models can segment networks that are
built with the NETGEAR Model DS508 and Model EN516 hubs and can function as bridges
connecting traditional 10BASE-T Ethernet networks to 100BASE-TX Fast Ethernet networks.

Prepare the Site
Before you begin installing your switch, prepare the installation site. Make sure
your operating environment meets the operating environment requirements of
the equipment.
Characteristic
Requirement
Temperature
Ambient temperature between 0° and 40° C (32° and 104° F).
No nearby heat sources such as direct sunlight, warm air
exhausts, or heaters.
Operating humidity Maximum relative humidity of 90%, noncondensing.
Ventilation
Minimum 2 inches (5.08 cm) on all sides for cooling.
Adequate airflow in room or wiring closet.
Operating
conditions
At least 6 feet (1.83 m) to nearest source of electromagnetic noise
(such as photocopy machine or arc welder).
Power
Adequate power source within 6 feet (1.83 m).
Install the Switch
To install your switch on a flat surface, you do not need any special tools. Be
sure the switch is positioned with at least 2 inches of space on all sides for
ventilation.
To install the switch in a rack, first attach the mounting brackets to the side of
the switch. Insert the screws provided in the rack mount kit through each bracket
and into the bracket mounting holes in the switch. Tighten the screws with a #1
Phillips screwdriver to secure each bracket. Align the mounting holes in the
brackets with the holes in the rack and insert two pan-head screws with nylon
washers through each bracket and into the rack. Tighten the screws with a #2
Phillips screwdriver to secure the switch in the rack.

Connect Devices to the Switch
Before connecting the switch, be sure you review “Applications” for information
about determining the appropriate configuration for your networking needs.
To connect the switch:
1. Connect the devices to the 10/100 Mbps ports on the switch, using
Category 5 UTP cable and an RJ-45 plug.
Note: Ethernet specifications limit the cable length between your PC or server and the
switch to 328 feet (100 meters) in length.
2. Set the Normal/Uplink push button.
3. Set the FDX/AUTO toggle switches on the rear panel for the selected
duplex mode (the default setting is AUTO).
4. Connect one end of the DC power adapter cable to the power outlet on
the rear panel of the switch and the other end of the power adapter
cable to the wall outlet.
Refer to the following illustration when connecting the switch. Each of the
preceding steps has a corresponding reference number in the illustration.

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.
