Description
The AT-FS20x and AT-FS202SC/FSx Series Fast Ethernet Switches include
the following models:
The AT-FS20x and AT-FS202SC/FSx 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 10/100Base-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 a 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.
AT-FS20x and AT-FS202SC/FSx 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.

AT-FS20x and AT-FS202SC/FSx Series Installation Guide
Twisted Pair Port
The AT-FS20x and AT-FS202SC/FSx Series Switches have one 10/
100Base-TX twisted pair port. The twisted pair port features a 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. Autonegotiation is designed to ensure 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 endnode 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 endnode is capable of full-duplex, the twisted pair port is set automatically to fullduplex mode. If the end-node is capable of half-duplex, 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.
5
Description
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-FS20x and AT-FS202SC/FSx Series 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 straightthrough cable when connecting a device to the twisted pair port.
Fiber Optic Port
The AT-FS20x and AT-FS202SC/FSx Series 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.
Switch Performance
The switches perform at:
❑148,800 pps for 100 Mbps and 14,880 pps for 10 Mbps for full wire
speed forwarding and filtering
❑200 Mbps maximum throughput in 100 Mbps, full-duplex mode
❑20 Mbps maximum throughput in 10 Mbps, full-duplex mode
AT-FS20x and AT-FS202SC/FSx Series Installation Guide
DIP Switches
The DIP switches are used to manually configure the operating characteristics
of the ports. These characteristics include the port speed, duplex mode, and
auto-negotiation.
On the 100Base-FX fiber optic port, you can manually set the duplex mode to
either half- or full-duplex.
On the 10/100Base-TX twisted pair port, you can manually set the speed of
the port to either 10 Mbps or 100 Mbps, set the duplex mode to either half- or
full-duplex and enable or disable auto-negotiation. Enabling auto-negotiation
will automatically set the port’s speed and duplex mode.
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-FS20x and AT-FS202SC/FSx Series Switches support store and
forward switching at Fast Ethernet full-wire speed in 100 Mbps, half- or fullduplex 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 endnode 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.

Troubleshooting
If the LNK/ACT LED for the fiber optic port is OFF, do the following:
❑Verify that the end-node connected to the port is ON and is operating
properly.
❑Check that the fiber optic cable is securely connected to the fiber optic
port on the switch and on the end-node.
❑Check to be sure that the end-node connected to the port is operating
at 100 Mbps.
❑Check to be sure that the end-nodes connected to the switch are
operating at the same duplex mode.
❑Make sure that the cable connected to the fiber optic receiver port on
the switch is connected to the transmitter port on the remote end-node
and that the fiber optic transmitter port on the switch is connected to
the receiver port on the end-node.
❑Test the attenuation on the fiber cable to ensure that it does not
exceed acceptable values.
❑Verify that you are using the appropriate type of fiber optic cables and
that you have not exceeded the maximum operating distance. For
cable types and operating distances, refer to Table 4 on page 10.
❑Check that the operating specifications of the fiber optic port on the
end-node are compatible with the operating specifications of the fiber
optic port on the switch. Refer to Table 5 on page 11 for the fiber optic
port specifications.
