100Base-FX Fiber Optic Port

The 100Base-FX fiber optic port can use either 50/125 or 62.5/125 micron
multimode fiber cabling and can operate up to a maximum distance of 2
kilometers (1.24 miles).

100Base-TX Twisted Pair Port

The 100Base-TX twisted pair port operates with Category 5 or better twisted
pair cabling and has a maximum operating distance of 100 meters (328 feet).
The port has an RJ-45 connector.

MDI/MDI-X Switch

The MDI/MDI-X (Media Dependent Interface/Media Dependent Interface with
Crossover) switch on the front panel of the unit eliminates the need for a
crossover cable when connecting a device to the twisted pair port on the media
converter. The MDI setting is typically used when connecting a DTE device
(such as a workstation or printer) to the twisted pair port. The setting of
MDI-X is typically used when connecting a switch to the port.

System and Port LEDs

Status LEDs are located on the front panel next to each port. Table 2 lists and
defines the LEDs.

MissingLink/Link Test Button

The MissingLink/Link Test (M/L ON/LNK TST) 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.

connections to the two ports on the media converter. The test determines
whether the ports are receiving a valid signal from the end nodes connected to
the ports. This test is typically used after installation to verify that the unit
and connections are operating properly, or whenever you need to test the ports
or the integrity of the connections to the nodes connected to the ports. The
section “Verifying the Installation” on page 15 contains instructions on how to
perform a link test.

MissingLink.

fiber optic port 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 a node, the device 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.

A link test is a fast and easy way for you to test the integrity of the

Note

Leaving the MissingLink/Link Test button 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 button is in the Link Test position.

The MissingLink feature enables the twisted pair port and 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.
In the example, once the end node connected to the fiber optic port has
realized that the connection to the end node on the twisted pair port has been
lost on the media converter, the end node can send a trap to the management
station, alerting the network administrator of the problem, or attempt to
establish a redundant path to the disconnected node.

AT-MC300 Series Installation Guide

Note

The MissingLink feature is disabled when the MissingLink/Link Test
button is in the Link Test position.

Auto-negotiation Button

The AT-MC300 Series Media Converter can operate in either half- or full­duplex mode. Duplex mode refers to the manner in which an end node sends
and receives data. An end node that is operating in half-duplex 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. The
best network performance is achieved when a node can operate in full-duplex,
since bandwidth is twice that compared to half-duplex.

The media converter is designed to determine the appropriate duplex port for
its ports through auto-negotiation. With auto-negotiation, the media converter
will determine the capabilities of the end nodes and will set the ports
accordingly. For instance, if the end nodes are capable of half-duplex mode
only, the unit will set its ports to half-duplex. It is important to note, however,
that both end nodes must operate with the same duplex mode. The network
will not function properly in situations where one end node is operating in
half-duplex and the other is operating in full-duplex.

The auto-negotiation feature on the media converter can be activated or
deactivated using the A/N button on the front panel. In nearly all situations,
you will want to leave the auto-negotiation capability activated on the
AT-MC300 Series Media Converter, so that the unit can determine the
appropriate duplex mode for the ports, based on the capabilities of the end
nodes. For example, auto-negotiation on the media converter should be left
activated in situations where both end nodes are also capable of auto­negotiation, or where both end nodes have been pre-set to the same mode, or
are capable of operating in only one duplex mode, such as half-duplex.

There is, however, one situation where it might be necessary for you to disable
auto-negotiation on the unit, and that is to prevent a mismatch from occurring
between the duplex modes of the end nodes. This can occur where one end
node is capable of only half-duplex mode while the other end node will auto­negotiate the duplex mode. For example, Figure 3 illustrates a media
converter that is interconnecting a 100Base-TX Ethernet hub capable of only
half-duplex operation and a 100Base-TX Ethernet switch that can auto­negotiate the duplex mode.

5

With auto-negotiation activated on the media converter, the unit will

determine that the hub is capable of half-duplex only, and will set the port
connected to the hub accordingly. In auto-negotiating with the switch, the
media converter will determine that the device is capable of full-duplex, and
will set the port connected to the switch to full-duplex. The result is referred to
as a classic duplex mode mismatch, where the end nodes are using different
duplex modes.

Duplex Mode Mismatch

There are two options to resolving this problem. One option is to manually
configure the port on the switch that is connected to the media converter so
that it operates only in half-duplex. The second option is to disable auto­negotiation on the media converter using the A/N button. With auto­negotiation disabled on the media converter, the switch will assume that the
media converter is capable of only half-duplex mode operation, and will set its
port accordingly, eliminating the mismatch in duplex modes between the end
nodes.

Note

Changing the A/N button setting requires that you power OFF and
power ON the media converter to activate the change on the unit.

AT-MC300 Series Installation Guide

Installing the Unit

This section contains the procedure for installing the media converter.

If you are building a back-to-back topology, please observe the following:

❑

During installation, setup, and testing of back-to-back media
converters, make sure each media converter is in the Link Test mode.

❑

When two media converters are connected back-to-back with no UTP/
STP cables connected and when the M/L ON/LNK TST button is in the
Link Test mode position (OUT), the fiber REC LEDs on each converter
may flash. This is normal and will not affect the normal operation of
the converters.

To install the media converter in either a standalone or back-to-back topology,
perform the following steps:

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

2. If you are installing the media converter on a desktop, attach the four
rubber feet to the base of the unit, placing one rubber foot in each corner.
(Do not attach the four rubber feet if you are installing the media
converter in an AT-MCR12 chassis.)

3. Set the M/L ON/LNK TST button to the Link Test mode (OUT) position.

4. Set the Auto-negotiation (A/N) button to either activate or deactivate
auto-negotiation of the duplex mode on the unit. For information on this
button, refer to “Auto-negotiation Button” on page 5.

5. If you are installing the unit in an AT-MCR12 chassis, refer to the
instructions included with the chassis for directions on how to insert the
media converter into the unit.

6. Plug the AC/DC power adapter into an appropriate AC power outlet and
insert the power plug into the DC receptacle located on the rear panel.
(This step does not apply if you installed the media converter in an
AT-MCR chassis.)

12 V DC Receptacle on Rear Panel

7. Verify that the PWR LED lights green.

8. Set the MDI/MDI-X button for the 100Base-TX twisted pair port to the
appropriate setting, as follows:

❑

If the twisted pair port on the media converter will be connected to an
MDI port on an end node (such as on a workstation or server), set the
button to the

❑

If the twisted pair port on the media converter will be connected to an

MDI-X

position. (MDI-X is the default position.)

MDI-X port on an end node (such as on a hub, switch, or another media
converter), set the switch to the

MDI

position.

9. Connect a Category 5 or better twisted pair cable to the RJ-45 connector on
the media converter. Connect the other end of the twisted pair cable to the
desired end node.

10. Remove the dust cover from the fiber optic port.

11. Connect the fiber cable to the fiber optic connector on the media converter.
Connect the other end of the cable to the desired end node.

12. Go to the next procedure, “Verifying the Installation”.

14

AT-MC300 Series Installation Guide

Verifying the Installation

To verify the installation and check to be sure that the media converter is
operating properly, perform the following procedure:

1. If you have not already, set M/L ON/LNK TST button to the Link Test
mode (OUT) position. If you installed a back-to-back topology, set both
media converters to the Link Test mode.

2. Power on the end nodes that are connected to the ports on the media
converter.

3. Verify that the LNK (Link) LED for the twisted pair port is ON.

4. Verify that the LNK (Link) LED for the fiber optic port is ON.

Note

If either LNK LED is OFF, refer to the next section, “Troubleshooting”
for guidelines on how to troubleshoot the unit.

5. Set the M/L ON/LNK TST button to the Link Test mode (OUT) position.

Note

When operating two media converters in a back-to-back configuration,
Allied Telesyn recommends that the MissingLink feature on one or both
of the converters be disabled. The MissingLink feature can be disabled
by placing the LNK TST button in the OUT position (LNK TST Mode).
The Link Test mode does not interfere with the converter’s ability to
pass network traffic.

The media converter is now ready to support network operations.

15

Troubleshooting

This section contains guidelines for troubleshooting the media converter. If a
problem occurs, set the M/L ON/LNK TST button to the Link Test mode
(OUT) position and then follow the instructions in this section.

If the PWR LED is OFF, verify the following:

❑

The power cord is securely connected to the power supply on the rear
panel of the media converter and to the power outlet.

❑

The power outlet has power. If necessary, test the power outlet by
connecting another device to it.

❑

The input power source is within the acceptable range for your area.

If the LNK LED for the fiber optic port is OFF, verify the following:

❑

The node connected to the port is powered ON.

❑

The fiber optic cable is securely and properly connected to the fiber
optic port. (The near end node transmitter (TX) cable should be
connected to the far end node receiver (RX) and vice versa.)

❑

The node connected to the fiber optic port is operating at 100 Mbps.

❑

The correct type of fiber optic cabling is being used to connect the end
node to the media converter (refer to Table 4 on page 11).

❑

The maximum allowable operating distance has not been exceeded.
(Refer to Table 4 and Table 5 on page 12.)

❑

The maximum allowable loss budget on the fiber optic cable is within
acceptable limits for full-duplex operation. (Refer to Table 4 on page

11.)

Note

In a back-to-back configuration where two media converters have been
interconnected via their fiber optic ports and the units are not in Link
Test mode, the LNK LEDs for the fiber optic ports will be OFF if the
connection to either end node (such as a switch or hub) is lost.

16

AT-MC300 Series Installation Guide

If the LNK LED for the twisted pair port is OFF, verify the following:

❑

The node connected to the port is powered ON.

❑

The twisted pair cable is securely connected to both the port on the
media converter and the end node.

❑

The MDI/MDI-X button is set to the correct position.

❑

Category 5 or better twisted pair cabling is being used to connect the
end node to the media converter.

❑

The maximum operating distance of 100 meters (328 feet) has not
been exceeded.

If the LNK LEDs are lit but there is communication problem between the end
nodes connected to the media converter, verify the following:

❑

Both end nodes are operating at 100 Mbps.

❑

Both end nodes are operating with the same duplex mode. If
necessary, use the Auto-Negotiation (A/N) button to deactivate auto­negotiation on the media converter. (Refer to “Auto-negotiation
Button” on page 5 for a description of the button.)

Note

Changing the A/N button setting requires that you power OFF and
power ON the media converter to activate the change on the unit.

❑

The correct type of fiber optic cabling and twisted pair cabling is being
used to connect the end nodes to the media converter.

❑

The maximum allowable loss budget on the fiber optic cable is within
acceptable limits for full-duplex operation. (Refer to Table 4 on page

11.)
