Overview
The AT-FS705LE Fast Ethernet Switch is a
10Base-T/100Base-TX unmanaged switch. The
switch provides you with a simple, cost-effective
solution for Ethernet switching between end-
nodes operating at either 10 Mbps or 100 Mbps.
Figure 1 and Figure 2 show the front and back
panels of the switch.

Key Features
The AT-FS705LE switch has the following
features:
❑Non-blocking architecture
❑Five Auto-Negotiating 10/100 Mbps
twisted pair ports with RJ-45 connectors
wired as MDI-X
❑One Auto-Negotiating 10/100 Mbps
uplink twisted pair port with RJ-45
connector wired as MDI. This port is used
to connect the AT-FS705LE switch to
another switch or hub without a crossover
cable.
❑External AC/DC power adapter
❑MAC address table with a capacity of
2,000 addresses.
❑Small compact size for use on a desktop or
wall-mountable

Physical Description
The physical description for the switch
includes:
❑Ports 1 through 4
❑Port 5 and the Uplink port
❑LEDs
❑Power Supply
❑MAC Address Table
Ports 1 Through 4
Ports 1 through 4 can operate at either 10 Mbps
or 100 Mbps and in either half- or full-duplex
mode. The ports, featuring RJ-45 connectors,
are configured as MDI-X, meaning that you can
connect a workstation or server to one of the
ports without using a crossover cable. The ports
have a maximum operating distance of 100
meters (328 feet) using Category 5 cable.
The ports are IEEE 802.3u Auto-Negotiation
compliant. This means that the ports can
automatically configure their speed and duplex
mode to match the capabilities of the end-nodes
connected to the ports.

Note
In order for a twisted pair port on the
AT-FS705LE switch to successfully Auto-
Negotiate its duplex mode with an end-
node, the end-node should also be using
Auto-Negotiation. Otherwise, a duplex
mode mismatch can occur. The twisted
pair port, using Auto-Negotiation, will
default to half-duplex if it detects that
the end-node is not using Auto-
Negotiation. This will result in a
mismatch if the end-node is operating at
a fixed duplex mode of full-duplex.
Port 5 and the Uplink Port
Port 5 and the Uplink port allow you to connect
an additional workstation to the switch or
interconnect the switch with another switch or
hub, without the use of a crossover cable. If you
need to connect an additional workstation to
the switch, use Port 5, which is configured as
MDI-X. If you need to connect the switch to
another Ethernet switch, use the Uplink port,
which is configured as MDI.

Both Port 5 and the Uplink port offer 10 Mbps
or 100 Mbps performance and Auto-Negotiation
operation for both speed and duplex mode. Both
ports feature a RJ-45 connector and have a
maximum operating distance of 100 meters
(328 feet) using Category 5 cable.
Note
You can use either Port 5 or the Uplink
port, but you cannot use both
simultaneously.

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, 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 or MDI-X,
you use a straight-through twisted pair cable.
To connect two network devices that have the
same wiring configuration, such as MDI to
MDI, you use a crossover cable.

The AT-FS705LE switch features auto MDI/
MDI/X on all ports. Auto MDI/MDI-X
automatically determines the configuration of
the port on the end-node 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
typically wired as MDI, the port on the switch
automatically configures itself as MDI-X. This
feature allows you to use a straight-through or
a crossover cable when connecting end-nodes to
the switch.
Auto-Negotiation
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.

Overview
8
Each twisted pair port on the AT-FS705LE
switch can operate in either half-duplex or full-
duplex mode. Since these twisted pair ports are
IEEE 802.3u-compliant, the duplex mode can
be set automatically through Auto-Negotiation.
With Auto-Negotiation, if the end-node is
capable of full-duplex, the port is set
automatically to full-duplex mode. If the end-
node is capable of half-duplex, the port is set
automatically to half-duplex mode.
Note
In order for the twisted pair port on the
AT-FS705LE switch to successfully Auto-
Negotiate its duplex mode with an end-
node, the end-node should also be using
Auto-Negotiation. Otherwise, a duplex
mode mismatch can occur. The twisted
pair port, using Auto-Negotiation, will
default to half-duplex if it detects that
the end-node is not using Auto-
Negotiation. This will result in a
mismatch if the end-node is operating at
a fixed duplex mode of full-duplex.
