Description

The AT-FS20x and AT-FS202SC/FSx Series Switches include the following
models:
The AT-FS20x Series switches are designed to extend the distance of your
network by converting Fast Ethernet data between twisted-pair cabling and
either multimode or single-mode fiber optic cabling. These dual-port switches
can also be used to improve the performance of your network by dividing it
into smaller, more manageable segments.
Each switch features a 100Base-FX fiber optic port and a 10Base-T/
100Base-TX twisted-pair port. The fiber optic port has either a SC or ST
connector and a maximum operating distance of 2 kilometers (1.2 miles) to
100 kilometers (62 miles), depending on the model. The twisted-pair port has
an RJ-45 connector with a maximum operating distance of 100 meters (328
feet).
The fiber optic port operates at 100 Mbps, while the twisted-pair port operates
at 10 Mbps or 100 Mbps. Both ports feature half- and full-duplex operation.
All of the AT-FS20x Series switches can be installed on a desktop or in an
AT-MCR12 chassis. These switches are easy to install and do not require
software configuration or management. This guide provides installation
instructions for installing the AT-FS20x Series Switches on a desktop. To
install the switches in an AT-MCR12 chassis, see AT-MCR12 Chassis
Installation Guide (PN 613-10725-00).

Twisted-Pair Port

The AT-FS20x and AT-FS202SC/FSx Series switches have one 10Base-T/
100Base-TX twisted-pair port. The twisted-pair port features an RJ-45
connector.

Port Speed

The twisted-pair port is compliant with the 10Base-T and 10Base-TX
standards and is capable of either 10 Mbps or 100 Mbps operation. You can set
the port speed manually or, since the port is IEEE 802.3u Auto-Negotiation
compliant, you can allow the switch to set the port speed automatically. With
Auto-Negotiation, the speed of the port is set automatically by the switch after
it determines the speed of the end-node connected to the port. Auto-
Negotiation ensures that the port on the switch and the end-node are
operating at the same speed and that they are communicating at the highest
possible common speed of the devices.

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 twisted-pair port on the switch can operated in either half- or full-duplex
mode. You can set the duplex mode manually or allow the switch to set it
automatically through Auto-Negotiation. With Auto-Negotiation, if the end-
node is capable of full-duplex mode, the twisted-pair port is set automatically
to full-duplex mode. If the end-node is capable of half-duplex mode, the port is
set automatically to half-duplex mode.

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, use a straight-
through twisted-pair cable. To connect two network devices that have the
same wiring configuration, such as MDI to MDI, use a crossover cable.
The AT-FS20x switches feature automatic MDI/MDI-X. The RJ-45 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 a device to the twisted-pair port.

Fiber Optic Port

The AT-FS20x switches have one 100Base-FX fiber optic port. The fiber optic
port features either an SC or ST connector.

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

The fiber optic port on the switch can operate in half- or full-duplex mode. You
must set the duplex mode manually using the DIP switches on the back of the
unit.
