Chapter 1
Overview
The AT-MC10x Series Fast Ethernet Media Converters include the
following models:
AT-MC101XL
AT-MC102XL
AT-MC103XL
AT-MC103LH
AT-MC104XL
AT-MC104LH
The AT-MC10x 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.
The AT-MC101XL, AT-MC102XL, AT-MC103XL, and AT-MC103LH
media converters feature a 100Base-TX twisted pair port and an
100Base-FX fiber optic port. The twisted pair port has an RJ-45 connector
and a maximum operating distance of 100 meters (328 feet). The fiber
optic port has a dual ST or dual SC connector and a maximum operating
distance of 2 kilometers (1.2 miles) to 40 kilometers (24.8 miles),
depending on the model.
The AT-MC104XL and AT-MC104LH media converters feature two
100Base-FX fiber optic ports with either dual SC or dual ST connectors.
One port uses multi-mode fiber optic cabling and has a maximum
distance of 2 kilometers (1.2 miles). The second port uses single-mode
fiber optic cabling and has a maximum distance of 15 kilometers (9.3
miles) to 40 kilometers (24.8 miles), depending on the model.
These media converters operate at 100 Mbps and feature half- and fullduplex operation.

AT-MC10x Series Media Converters Installation Guide
Auto MDI/MDI-X
An RJ-45 twisted pair port on an 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.
The AT-MC10x Series media converters feature automatic MDI/MDI-X.
The 100Base-TX 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 media converter is connected to
a port on a bridge, which is typically wired as MDI, the port on the media
converter automatically configures itself as MDI-X. This feature allows
you to use a straight-through cable when connecting any type of device to
the media converter.
Link Test (LINK TST)/MissingLinkTM (M/L) Button
The LINK TST/M/L 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
The link test is a fast and easy way for you to test the connections
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 port and end-node where the problem resides.
A link test is performed when the button is in the LINK TST (OUT)
position. For instructions on performing a link test, refer to
“Troubleshooting” on page 33.
Note
Leaving the media converter in the LINK TST (OUT) position will
not interfere with the units ability to pass network traffic.
7
Chapter 1: Overview
MissingLink
The MissingLink feature enables the fiber optic ports on the 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 an end-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 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 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.
Auto-Negotiation Button
The Auto-Negotiation (A/N) button, located on the front panel of the
AT-MC101XL, AT-MC102XL, and AT-MC103XL/LH, enables and
disables the Auto-Negotiation 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
an end-node sends and receives data on the network. An end-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. An endnode operating in full-duplex can send and receive data simultaneously.
The best network performance is achieved when an end-node can
operate in full-duplex mode.
8
AT-MC10x Series Media Converters Installation Guide
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 endnodes have been pre-set 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 8
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 endnodes.

Figure 8. Example of a Duplex Mode Mismatch
You can resolve the mismatch in one of two ways:
Manually configure Unit 2, if possible, so that the port connected to
the media converter is set to half-duplex.
Disable Auto-Negotiation on the media converter using the Auto-
Negotiation button. With Auto-Negotiation on the media converter
disabled, Unit 2 will assume that the converter is capable of only halfduplex operation, thus eliminating the mismatch in duplex modes
between the end-nodes.

Chapter 1: Overview
Note
After a configuration change, you must reset the media converter
by powering OFF then powering ON the unit
On the AT-MC101XL, AT-MC102XL, AT-MC103XL, and
AT-MC103LH models, set the Auto-Negotiation feature as follows:
If both end-nodes will use Auto-Negotiation to determine the
duplex mode, or if both are pre-set to operate with the same
duplex mode, such as half-duplex, set the switch to the A/N ON
(IN) position. This is the default setting.
If one end-node is capable of operating at only half-duplex mode
while the other node will determine its duplex mode through AutoNegotiation, set the switch to the A/N OFF (OUT) position.
External AC/DC Power Adapter
An external AC/DC power adapter is included with the media converter
for standalone operation. The power adapter supplies 12V DC to the
media converter. Allied Telesyn supplies an approved safety compliant
AC power adapter for the 120 and 240V AC versions with an unregulated
output of 12V DC at 1 A. The power required for the media converter is
12V DC, 500 mA.
