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.

Figure 3 Twisted Pair Port and Fiber Optic Port Channel (Model AT-MCF112SC)

Twisted Pair Ports

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 Ports

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.

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 Switch

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.

6

AT-MCF106xx and AT-MCF112xx Installation Guide

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.

Overview

Duplex Mode DIP 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 Switches

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 half­duplex 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.

AT-MCF106xx and AT-MCF112xx Installation Guide

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.

Power 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.

Warning
Power cord is used as a disconnection device: To de-energize

equipment, disconnect the power cord.  10

Optional Redundant Power 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.

The media converter can be installed as a standalone unit (for instance, on a
table) or in a standard 19-inch rack. To install the unit in a rack, refer to
“Installing the Media Converter in a Rack” on page 20. To install the media
converter as a standalone unit, perform these steps:

1. Remove all equipment from the shipping package and store the package
in a safe place.

Caution

Do not remove the dust covers from the fiber optic ports on the media
converter until you are ready to connect the cables. Dust contamination
can adversely impact the operation of the fiber optic ports.

2. Select a level, secure surface for the media converter.

3. Remove the adhesive protecting sheet from the rubber feet included with
the unit and affix the feet to the corners on the bottom of the media
converter, approximately 1 centimeter (0.39 inches) from each edge.

4. Place the device horizontally on a hard, clean surface (for example, a table
or desk), leaving free space around it for ventilation.

Note

Do not place the unit on other active, heat generating equipment and
avoid placing other devices on top of the media converter.

5. If you purchased an optional redundant power supply for the media
converter, install the redundant power supply by following the directions
included with the unit.

Note

Do not remove the panel covering the expansion slot for the redundant
power supply unless you intend to install the unit.

6. Plug the power cord into the back of the unit and plug the other end of the
power cord into a power outlet. If you installed an optional redundant
power supply, plug its power cord into the power supply and the other end
into a power outlet.

18

equipment, disconnect the power cord.  10

If you installed an optional redundant power supply, you should connect
the media converter’s two power cords to power outlets that are on
different circuits. This will protect the media converter from a loss of
power should a power circuit fail.

7. Remove the dust covers from the fiber optic ports.

Laser

Do not stare into the laser beam.  7

8. Connect the twisted pair cables and fiber optic cables to their respective
ports. As you connect the cables, observe these guidelines:

q To connect a hub or switch to a twisted pair port, use a straight-

through cable.

q To connect a workstation to a twisted pair port, use a crossover cable.
q With ST fiber optic connectors, be sure to correctly connect the cables

to the port connectors: that is, the transmitting (TX) fiber optic cable
should be connected to the RX port and the receiving cable should be
connected to the TX port.

9. Set each DIP switch to reflect the duplex mode of the two end nodes
connected to the ports of the corresponding channels.

Below are guidelines to help you in setting a channel’s duplex mode.

q If both end nodes connected to the two ports on a channel are capable

of only half-duplex mode, set the channel to half-duplex (HDX).

q If both end nodes are capable of full-duplex mode, set the channel to

full-duplex (FDX).

q If both end nodes can auto-negotiate the duplex mode, set the channel

to full-duplex.

19

Installation

q If one end node is capable of only half-duplex mode while the other end

node will auto-negotiate the duplex mode, set the channel setting to
half-duplex. (Failure to set the channel to half-duplex in this situation
will result in what is referred to as a classic duplex mode mismatch,
where one node will operate in half-duplex while the other node will
operate in full-duplex. This can result in poor network performance.)

10. Press the Reset button on the front of the unit.

11. Go to “Troubleshooting” on page 25 for instructions on how to test the
media converter.

11. Press the Reset button on the front of the unit.

12. Go to the next procedure, “Verifying the Installation,” for instructions on
how to test the media converter.

Verifying the Installation

The procedure in this section has you test the unit by performing a link test. A
link test will determine whether each fiber optic port on the unit is receiving a
signal from the node connected to it. You should perform this test immediately
after you have installed the unit or whenever you need to test the integrity of
the fiber optic connections to the fiber optic ports on the unit.

Note

In order to run a link test, the nodes connected to the ports on the media
converter must be powered ON and operating.

To perform a link test, follow these steps:

1. Verify that the Main LED is a steady green, indicating that the unit is
receiving power.

22

AT-MCF106xx and AT-MCF112xx Installation Guide

2. If you installed an optional redundant power supply, check that the
BCKP LED is a steady green.

3. Check to be sure that the fans for the main power supply and the optional
redundant power supply, if installed, are operating.

4. Set the Link Test switch to the Test position. If you are installing an
AT-MCF112xx unit, set both Link Test switches to the Test position.

The Test LED next to the Link Test switch(es) should be amber.

5. Check that each F-LNK LED for each fiber optic port on the media
converter is lit, indicating that a link exists between the fiber optic port
on the media converter and the node connected to the port.

6. If one or more of the F-LNK LEDs for the fiber optic ports are not lit, refer
to “Troubleshooting” on page 25.

7. Set the Link Test switch(es) to Normal.

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.

The multichannel media converter is now ready for normal network
operations. For information on the statusLEDs, refer to

“Status LEDs” on

page 5.

Chapter 3

Troubleshooting

This section contains guidelines for troubleshooting the media converter in
the event a problem occurs.

If the Main LED is OFF, check the following:

q Check to be sure that the power cord for the main power supply is

securely connected to the power supply and the power outlet.

q Check that the power outlet has power by connecting another device

to it.

q Check that the input power source is within the acceptable range. For

AC models, the range is between 100 and 240 VAC.

If an optional redundant power supply is installed but the BCKP LED is OFF,
check the following:

q Check to be sure that the power cord for the redundant power supply

is securely connected to the media converter and the power outlet.

q Press the Reset button on the front of the media converter to reset the

unit.

q Check that the power outlet has power by connecting another device

to it.

q Check that the input power source is within the acceptable range. For

AC models, the range is between 100 and 240 VAC.

If the F-LNK LED for a fiber optic port is OFF, check the following:

q Check to be sure the node connected to the port is powered ON.
q Check to be sure that the fiber optic cable is properly connected to the

fiber optic port.

q Check to be sure that the node connected to the port is operating at

100 Mbps.

q Verify that the maximum allowable loss budget on the fiber optic cable

is within acceptable limits (see Table 4).

25

Troubleshooting

If the T-LNK LED for a twisted pair port is OFF, check the following:

q Check to be sure the node connected to the port is powered ON.
q Check to be sure that the twisted pair cable is securely connected to

both the port on the media converter and the node.

q If the node connected to the port is a workstation, check to be sure that

you used a crossover cable. (A crossover cable is not necessary when
connecting a hub or switch to a twisted pair port on the media
converter.)

If a Link LED of a port is lit but there is communication problem with the
port, check the following:

q Check to be sure that the node connected to the port is operating at

100 Mbps.

q Check to be sure that the duplex setting is set the same on the two

nodes connected to the twisted pair and fiber optic ports of a channel
on the media converter. For example, if the node connected to a
twisted pair port is set to full-duplex, then the node connected to its
corresponding fiber optic port must also be set to full-duplex.

Resetting the Unit

In some instances you might need to reset the unit. To do so, press the Reset
button on the front of the unit for about 1 second. The LEDs on the unit will
flash once, after which the unit is ready for normal network operations.
