AT-MC103ST/FS4
The AT-MC100 Series Fast Ethernet Media Converters are designed to extend
the distance of your network by interconnecting LAN devices that are
physically separated by large distances. Each media converter features a
100Base-TX twisted pair port and a 100Base-FX fiber optic port. The twisted
pair port has an RJ-45 connector and a maximum distance of 100 meters (328
feet). The fiber optic port has an ST or SC connector and a maximum distance
of 2 kilometers (1.2 miles) to 100 kilometers (62 miles), depending on the
model. These units operate at 100 Mbps and feature half-duplex and fullduplex operation.
The media converters can be installed either as standalone units, such as on a
table, or in an AT-MCR12 Rackmount Chassis or AT-TRAY4 Rackmount
Tray. The AT-MC101, AT-MC102, and AT-MC103 Series Media Converters
are easy to install and do not require any software configuration or
management. Figure 1 shows an example of an AT-MC100 Series Media
Converter.

MDI/MDI-X Button
The MDI/MDI-X button, located on the front of the unit, is a straight-through
or crossover cable selection feature. It allows you to connect the RJ-45 port to
a repeater or DTE device without using a special crossover cable. The default
position is MDI-X (OUT), which means you can connect the RJ-45 port to a
workstation or to any other DTE device using a straight-through cable.

Link Test/MissingLink Button
The Link Test/MissingLink button allows you to perform a link test on the
ports on the media converter. This button also allows you to activate the
MissingLink feature on the unit. Both features are describe in the following
section.
Link Test.
between the ports on the media converter and the nodes that are connected to
the ports. If a network problem occurs, you can perform a link test to
determine which port is experiencing a problem, and be able to focus on the
fiber optic cable and node where the problem resides.
A link test is performed when the button is in the LNK TST (OUT) position.
For instructions on performing a link test, refer to “Testing the Installation”
on page 13.
MissingLink.
media converter to pass the “Link” status of their connections to each other.
When the media converter detects a problem with one of the ports, such as the
loss of connection to a node, the media converter shuts down the connection to
the other port, thus notifying the node that the connection has been lost.
For example, if the network twisted pair cable to the 100Base-TX port on the
media converter were to fail, the media converter would respond by dropping
the link on the 100Base-FX fiber optic port. In this way, the media converter
notifies the end node connected to the fiber optic port that the connection on
the twisted pair port has been lost. If the failure had started with the fiber
optic cabling, the unit would drop the link to the twisted pair port.
The link test is a fast and easy way for you to test the connections
Note
Performing a link test does not interfere with a media converter’s ability
to pass network traffic.
The MissingLink feature enables the fiber optic ports on the
The value to this type of network monitoring and fault notification is that
some hubs and switches can be configured to take a specific action in the event
of the loss of connection on a port. In some cases, the unit can be configured to
seek a redundant path to a disconnected node or send out a trap to a network
management station, and so alert the network administrator of the problem.
Note
The MissingLink feature is disabled when you perform a link test with
the Link Test/MissingLink button. Consequently, to ensure that the
MissingLink feature is activated on the media converter, always set the
button to the M/L ON (IN) position during normal network operations.

AT-MC100 Series Installation Guide
Auto-negotiation Button
The auto-negotiation button, located on the front panel, disables the autonegotiation feature (IEEE 802.3u) of the media converter. The media
converter uses auto-negotiation to determine the duplex mode of the ports.
The duplex mode refers to the manner in which a node sends and receives
data on the network. Depending on its capabilities, a node can operate in
either half- or full-duplex mode. A node operating in half-duplex can either
send or receive data, but not both at the same time. However, a node
operating in full-duplex can send and receive data simultaneously. The best
network performance is achieved when a node can operate in full-duplex
mode.
In most configurations, you will want to leave the auto-negotiation button
activated so the unit can determine the appropriate duplex mode, based on the
capabilities of the end nodes. For example, the auto-negotiation feature on the
media converter should be left activated in situations where both end nodes
are also capable of auto-negotiation, or where both end nodes have been preset to the same mode or are capable of operating in only one duplex mode, such
as half-duplex.
There is one situation where it may be necessary to disable the autonegotiation feature, and that is to prevent a mismatch from occurring between
the duplex modes of the end nodes. For example, Figure 2 shows two units
that have been connected with a media converter. Unit 1 is a repeater that is
capable of operating in half-duplex mode only. Unit 2 is a switch that can
operate in either half- or full-duplex mode, and will auto-negotiation the
duplex mode.
In attempting to auto-negotiate with Unit 1, the media converter will
determine that the unit is capable of half-duplex only and will set the port
connected to the unit appropriately. In auto-negotiating with Unit 2, the
media converter will determine that the unit can manage full-duplex and will
set the port connected to the unit to full-duplex. The result is a mismatch,
with one unit operating in half-duplex and the other unit operating in
full-duplex. This is referred to as a classic duplex mode mismatch and will
result in poor network performance between the end nodes.
