Chapter 1
Overview
The AT-FS713FC/xx and AT-FS717FC/xx Series Fast Ethernet Switches
include the following models:
These units are unmanaged Layer 2 switches. These switches can be used as a
‘bridge’between the different workgroups in your network or they can be used
to create small workgroups with dedicated 10/100 Mbps links to your network
devices. They can also be used to connect to other Ethernet switches so that
they can be part of a larger Ethernet network.
The AT-FS713FC/xx Series Switches feature twelve 10/100Base-TX twisted
pair ports and a 100Base-FX fiber optic port. The twisted pair ports have a
RJ-45 connector and a maximum operating distance of 100 meters (328 feet).
The fiber optic port has a FJ, LC, MT, SC, ST, or VF connector, depending on
the model, and a maximum operating distance of 2 kilometers (1.2 miles).
The AT-FS717FC/xx Series Switches feature sixteen 10/100Base-TX twisted
pair ports and a 100Base-FX fiber optic port. The twisted pair ports have a
RJ-45 connector and a maximum operating distance of 100 meters (328 feet).
The fiber optic port has a FJ, LC, MT, SC, ST, or VF connector, depending on
the model, and a maximum operating distance of 2 kilometers (1.2 miles).
The fiber optic port operates at 100 Mbps and features half- and full-duplex
operation. The twisted pair port operates at 10 or 100 Mbps and auto-
negotiates the duplex mode.
The AT-FS713FC/xx and AT-FS717FC/xx Series Switches are easy to install
and do not require software configuration or management.

Twisted Pair Ports
The AT-FS713FC/xx and AT-FS717FC/xx Series Switches have twelve and
sixteen 10/100Base-TX twisted pair ports, respectively.
Port Speed
The twisted pair ports are compliant with the 10Base-T and 10Base-TX
standards and are capable of either 10 Mbps or 100 Mbps operation. The ports
are IEEE 802.3u auto-negotiation compliant. The speed of the port is set
automatically by the switch after determining the speed of the end-node
connected to the port. Auto-negotiation is designed to ensure that each port on
the switch and the end-node connected to each port are operating at the same
speed and that they are communicating at the highest possible common speed
of the devices.
Duplex Mode
The twisted pair ports on the switches can operated in either half- or full-
duplex mode and are set automatically through auto-negotiation. If the end-
node is capable of full-duplex mode, the twisted pair port is set to full-duplex.
If the end-node is capable of half-duplex mode, the port is set to half-duplex.
Auto MDI/MDI-X
An RJ-45 twisted pair port on a 10 Mbps or 100 Mbps Ethernet network
device can have one of two possible wiring configurations: MDI or MDI-X. The
RJ-45 port on a PC, router, or bridge is typically wired as MDI, while the
twisted pair port on a switch or hub is usually MDI-X.
To connect two 10 Mbps or 100 Mbps network devices together that have
dissimilar port wiring configurations, such as MDI to MDI-X, you would
usually use a straight-through twisted pair cable. To connect two network
devices that have the same wiring configuration, such as MDI to MDI, you
would usually use a crossover cable.
The AT-FS713FC/xx and AT-FS717FC/xx Series Switches feature automatic
MDI/MDI-X. Each port automatically determines the configuration of the port
on the device to which it is connected and then configures itself appropriately.
For example, if a port on a switch is connected to a port on a bridge, which is
typically wired as MDI, the port on the switch automatically configures itself
as MDI-X. This feature allows you to use either crossover cables or straight-
through cables when connecting devices to these switches.

6
Fiber Optic Port
The AT-FS713FC/xx and AT-FS717FC/xx Series Switches have one
100Base-FX fiber optic port. The fiber optic port has a FJ, LC, MT, SC, ST, or
VF connector, depending on the model.
Port Speed
The fiber optic port is compliant with the 100Base-FX standard and has a
fixed operating speed of 100 Mbps. The end-node connected to the fiber optic
port on the switch must also be able to operate at 100 Mbps.
Duplex Mode
Duplex mode refers to the way an end-node sends and receives data on the
network. An end-node can operate in either half- or full-duplex mode,
depending on its capabilities. An end-node that is operating in half-duplex
mode can either send data or receive data, but it cannot do both at the same
time. An end-node that is operating in full-duplex mode can send and receive
data simultaneously. The best network performance is achieved when an end-
node can operate at full-duplex, since the end-node is able to send and receive
data simultaneously.
The AT-FS713FC/xx and AT-FS717FC/xx Series Switches can operate in
either half- or full-duplex mode. To set the duplex mode on the fiber optic port,
slide the 100FX DUPLEX switch UP (half-duplex) or DOWN (full-duplex). The
switch can operate with end-nodes capable of either half-duplex mode or full-
duplex mode.

AT-FS713FC/xx and AT-FS717FC/xx Series Installation Guide
7
MAC Address Table
Up to 4,000 MAC addresses can be stored in the switch’s MAC address table.
The switch’s self-learning feature will learn all new addresses in real-time
after power-up. If the source address of an incoming packet is not found in the
MAC address table, the switch will update the table with the new address.
The switch also has an automatic address aging feature that will delete a
source address from the table if it has not seen a frame from the end-node
with that address within five minutes. This prevents the table from becoming
filled with addresses of end-nodes that are no longer active.
The switch forwards all multicast, broadcast, and unicast packets when the
MAC address table has exceeded its storage limit.
Store and Forward
The AT-FS713FC/xx and AT-FS717FC/xx Series Switches support store and
forward switching at Fast Ethernet full-wire speed in 100 Mbps, half- or full-
duplex mode. Packets entering each port are stored in buffers. Once the full
packet is received, the switch will forward or discard the packet, depending on
its destination address and error status. This ensures that only error-free
packets destined for another segment will be transferred across the switch,
reducing network load. For example, if the packet entering from Port 1 is
destined for an end-node on Port 2, the switch forwards the frame if the frame
does not contain any errors. If the packet from Port 1 is destined for an end-
node also connected to Port 1, the packet is discarded.
The switch will discard CRC errors, misaligned, runt, and under-oversized
packets. When the packet has dribble bits at the end, the switch will truncate
to octet boundary and check for a good FCS before forwarding.

8
Network Topologies
The AT-FS713FC/xx or AT-FS717FC/xx Series Switches can be used in
several network topologies. Some of these topologies are described below.
Workgroup Topology
Figure 3 illustrates a workgroup topology where each end-node is connected
directly to a port on an AT-FS713FC/SC switch, giving each end-node a
dedicated 10 Mbps or 100 Mbps link.

Ethernet Hub Workgroup Topology
Figure 4 illustrates an Ethernet hub workgroup topology where an
AT-FS713FC/SC is used to connect together four 10/100 Mbps Ethernet hubs.
This allows the switch to function as a bridge between the different
workgroups by controlling the flow of data between the workgroups. The
switch transfers an Ethernet frame from hub-to-hub only when the
destination end-node for the frame is on a different hub than the end-node
that originated the frame. This reduces the amount of unnecessary data traffic
in each workgroup. This frees up bandwidth and improves network
performance.

Backbone Topology
If your network consists of several AT-FS713FC/xx or AT-FS717FC/xx Series
Switches, then you will probably want to connect them together to form an
integrated network. Here the fiber optic ports can be extremely useful. You
can use the ports to create a fiber optic backbone. With a maximum operating
distance of 2 kilometers (1.2 miles), the ports can be used to connect together
switches that are physically far apart. Figure 5 shows an AT-FS713FC/ST
switch and an AT-FS717FC/ST switch interconnected using the fiber optic
ports to create a backbone topology.
