Chapter 1
Overview
The Ethernet AT MCF106xx and the AT MCF112xx Series Multichannel
Media Converters are designed to extend the reach of your network by
converting your twisted pair cabling into fiber optic cabling. These products,
which transfer Ethernet data between 100Base TX and 100Base FX
technologies, enable you to quickly and easily interconnect the nodes in your
network to distances of 2 kilometers (1.24 miles) to 40 kilometers (24.8 miles),
depending on the model. With this product, remote devices and networks,
which previously were difficult to interconnect, are easily interconnected to
form one integrated network.
The ports on the media converters are grouped into pairs, referred to as
“channels,” with each pair consisting of a 100Base TX twisted pair port and a
100Base FX fiber optic port. Each channel functions as an independent media
converter. The Ethernet AT MCF106xx unit features six channels, providing
you with six individual media converters, while the AT MCF112xx unit
features twelve channels, giving you twelve individual media converters.
The twisted pair ports are designed to operate with Category 5 or better
cabling at a speed of 100 Mbps. The fiber optic ports, which also operate at a
speed of 100 Mbps, are available in a variety of connector types and support
IEEE standard Multimode Fiber (MMF) or Single Mode Fiber (SMF) cable.
The media converters can be installed either as standalone units, such as on a
table, or in a standard 19 inch rack. The units are easy to install and do not
require any software configuration or software management.
Optional Management Module
The AT MCM02 is an optional management module for the AT MCF106xx
and AT MCF112xx Series Multichannel Media Converters. When installed,
the AT MCM02 module allows you to monitor the operating status of the
media converter from a management station on your network using either the
Telnet application protocol or an SNMP management program.

Twisted air and Fiber Optic orts
The twisted pair and fiber optic ports on the unit are paired together (see
Figure 3). Each pair is referred to as a “channel” and each channel functions
as an independent media converter. The AT MCF106xx Multichannel Media
Converter has six channels while the AT MCF112xx Series Multichannel
Media Converter has twelve channels.
Figure 3 T isted Pair Port and Fiber Optic Port Channel (Model AT-MCF112SC)
Twisted air orts
The twisted pair ports are IEEE 802.3 100Base TX compatible, and thus
operate at 100 Mbps only. The ports require Category 5 or better cabling and
allow for a distance of 100 meters (328 feet).
The devices that you connect to the twisted pair ports must operate at 100
Mbps. To connect a switch, hub, or router to one of these ports, you will use a
straight through cable. Connecting a workstation to a twisted pair port
requires a crossover cable.
100Base-FX Fiber Optic orts
The 100Base FX fiber optic ports operate at 100 Mbps and, depending on the
model, operate with multimode or single mode fiber optic cabling.
The type of connector on the fiber optic ports will depend on the system model
you purchased. Refer to Table 1 on page 2 for the available types of
connectors.

Status LEDs
The media converter does not require any software configuration or software
management. The status of the unit can be determined by viewing the LEDs
on the front of the unit. Table 2 lists the functions of the power supply and
Link Test switch LEDs.
Each twisted pair port has one LED labelled T LNK that indicates whether or
not a link has been established between the port and the node connected to
the port. Each fiber optic port has two LEDs, one labelled F LNK that lights
when a link has been established with the node connected to the port and
another LED labelled Active that lights when the port is receiving traffic.
Table 3 lists the functions of the port LEDs.

Link Test Switch
The Link Test switch is a fast and easy way for you to test the integrity of the
fiber optic connections to the fiber optic ports on the media converter (see
Figure 4). The AT MCF106xx unit has one Link Test switch which is used to
test all six fiber optic ports on the unit. The AT MCF112xx unit has two Link
Test switches; one switch is used to test the fiber optic ports in channels 1
through 6 and the second switch is used to test the fiber optic ports in
channels 7 through 12 on the unit.
Figure 4 Link Test S itch
The Link Test switch is used after installation to verify that the unit and
connections are operating properly, or whenever you need to test the fiber
optic ports or the integrity of the fiber connections to the nodes connected to
the ports.
The LED next to the Link Test switch indicates the operating mode of the
fiber optic ports. If the Test LED is lit amber, a link test is being performed on
the fiber optic ports associated with the switch. The section “Troubleshooting”
on page 25 contains instructions for performing a link test.
Note
Leaving the Link Test switch in the Link Test position will not affect
the operation of the media converter during normal network operations.
However, the MissingLink feature of the media converter is disabled
when the switch is in the Link Test position. Consequently, it is
recommended that the Link Test switch be set to the Normal position
during normal network operations.

MissingLink Feature
The MissingLink™ feature enables the twisted pair and fiber optic ports of
each channel on the media converter to pass the “Link” status of their
connections to each other. When a channel detects a problem with one of the
ports, such as the loss of connection to a node, the channel shuts down the
connection to the other port of the channel, thus notifying the node that the
connection has been lost.
For example, Figure 5 illustrates the two ports of Channel 1 on an
AT MCF106xx unit. The twisted pair port in Channel 1 is connected to a port
on an AT 8224XL Ethernet switch and the fiber optic port is connected to an
AT FS709FC Ethernet switch. If the fiber optic cable to the AT FS709FC
switch experiences a failure, the MissingLink feature in the channel will
detect the problem and drop the link on the twisted pair port. In this way, the
AT MCF106xx unit notifies the AT 8224XL Ethernet switch that the
connection to the AT FS709FC Ethernet switch has been lost. If the failure
had started with the twisted pair cabling, the MissingLink feature would drop
the link to the fiber optic port.
Figure 5 MissingLink Example
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.
In the example above, once the AT 8224XL Ethernet switch realizes that its
connection has been lost to the media converter, and, consequently, to the
AT FS709FC switch, the switch can send a trap to the management station,
alerting the network administrator of the problem.
Note
The MissingLink feature is disabled when you perform a link test with
the Link Test switch. Consequently, to ensure that the MissingLink
feature is enabled on the media converter, always set the Link Test
switch to the Normal position during normal network operations.

Duplex Mode DI Switches
The AT MCF106xx and AT MCF112xx Series Multichannel Media Converters
include DIP switches (Figure 1) on the front panel for controlling the duplex
mode of the individual media converter channels. You use the DIP switches to
set each channel to either half or full duplex operation. The AT MCF106xx
Series Multichannel Media Converter has one set of DIP switches while the
AT MCF112xx Series has two sets of switches. Each DIP switch must be et to
reflect the duplex node of the two end nodes connected to the ports of the
corresponding channel.
Figure 6 Duplex Mode DIP S itches
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 duplex mode or full duplex mode. A node that is operating in half
duplex mode can either send data or receive data, but not both at the same
time. A node that is operating in full duplex mode can send and receive data
simultaneously. Naturally, the best network performance is achieved when a
node can operate at full duplex, since the node is able to both send and receive
data at the same time.
The two nodes that are connected to the same twisted pair and fiber optic
ports of a channel on the media converter must operate with the same duplex
mode, otherwise the duplex mode mismatch can occur. For example, assume
that you connected a node operating at half duplex to the twisted pair port of a
channel on the media converter and a node operating at full duplex to the
fiber optic port of the same channel. This would be an invalid configuration
and could adversely affect the performance of the network. Either the node
connected to the twisted pair port would have to be changed to full duplex (if it
supports that capability), or the node connected to the fiber optic port would
need to be changed to half duplex.
The DIP switch labeled NORM / TEST is used to activate the MissingLink
feature on the unit and to perform a link test on the ports of the media
converter.

Reset Button
The Reset button allows you to reset the ports on the unit. You might need to
reset the ports after completing the installation or after adding or swapping a
power supply. You must reset the unit after a power disruption or whenever a
general power failure status is observed.
ower Inlet
The unit does not have an ON/OFF power switch. Power is applied to and
removed from the system by connecting and disconnecting the power cable.
Warnin
Power cord is used as a disconnection device: To de energize
equipment, disconnect the power cord.  10
Optional Redundant ower Supply Slot
The rear panel of the media converter contains an expansion slot for an
optional redundant power supply. When installed, the optional power supply
shares the load of powering the unit with the standard power supply that
comes with the system. If one power supply fails, the remaining unit assumes
the role of providing all power to the system, thereby protecting the unit from
a system failure.
An LED on the front panel of the unit reflects the status of an optional
redundant power supply, if installed. When the redundant power supply is
operating properly, its LED is a steady green.
Both the redundant power supply and the main power supply can be “hot
swapped.” This means that should either power supply fail, the failed unit can
be removed and replaced with a new power supply while the unit is operating,
without network operations being interrupted.
Each power supply has its own power cord. By connecting the two power cords
to outlets on separate power supply circuits, you increase the protection to
your media converter from operational failure should a power circuit fail.
Note
A redundant power supply is strongly recommended for the
AT MCF112xx Multichannel Media Converter to help avoid a “single
point of failure” to as many as twelve links.

Network Topology
The value of the AT MCF106xx and AT MCF112xx Series Multichannel
Media Converters is that they allow you to extend the reach of your network
and to interconnect widespread network devices and subnetworks into one
integrated network.
Figure 8 on page 11 illustrates an example of a network that incorporates a
AT MCF106SC unit to interconnect dispersed network devices. The model has
SC type fiber optic connectors and a range of 2 kilometers (1.24 miles) on the
fiber optic ports. At the top of the topology is an AT 8224XL Fast Ethernet
switch. Six of the twisted pair ports on the switch are connected to the six
twisted pair ports on the AT MCF106SC media converter. Fiber optic cabling
from the AT MCF106SC unit connects the media converter to the switches,
hubs, and workstation that comprise the network.
