Fiber Optic Port
The 1000Base-SX port on the AT-MC1004 media converter has an SC
connector and is designed to operate with multimode fiber optic cabling. This
port has a maximum operating distance of 550 meters (1,804 feet) using 62.5/
125 micron multimode fiber optic cable.
The 1000Base-LX port on the AT-MC1005/x Series Media Converters has an
SC connector and is designed to operate with single-mode fiber optic cabling.
This port has a maximum operating distance of 10 kilometers (6.2 miles) to 70
kilometers (43.4 miles), depending on your model, using 9/125 micron single-
mode fiber optic cable.
Mode Selection Button
Link Test
The link test is a fast and easy way for you to test the connections between the
Gigabit Ethernet media converter ports and the end-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 your
troubleshooting efforts on the cable and end-node where the problem resides.
A link test is performed when the Mode Selection button is toggled until the
LT LED is green.
Note
Performing a link test does not interfere with a media converter’s ability
to pass network traffic.
MissingLink
The MissingLink feature enables the fiber optic ports on the Gigabit Ethernet
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 end-node that the connection
has been lost.

AT-MC1004 and AT-MC1005/x Series Installation Guide
5
For example, if the network twisted pair cable to the 1000Base-T port on the
media converter were to fail, the unit would respond by dropping the link on
the 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 devices 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 end-node or send out a trap to a network
management station, and so alert the network administrator of the problem.
Note
MissingLink or Smart MissingLink is disabled when you perform a link
test. Consequently, to ensure that the MissingLink or Smart
MissingLink is enabled on the media converter, always set the Mode
Selection button so that the ML or SML LED is green during normal
network operations.
Smart MissingLink
Like MissingLink, the Smart MissingLink feature terminates the link on the
failed port thereby notifying you when a connection has been lost.
Additionally, Smart MissingLink indicates on which port the connection has
failed. This is shown by a blinking LNK LED on the good port.
For example, if the network twisted pair cable to the 1000Base-T port on the
media converter were to fail, the LNK LED on the fiber optic port will blink,
indicating a failed connection on the twisted pair port. The fiber optic port is
still able to receive a signal.
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 LNK LED on the twisted pair port
would blink.
The value to this type of network monitoring and fault notification is so that
you can quickly see which port has failed and troubleshoot your network
accordingly.

Overview

Half- and Full-Duplex Mode
Duplex mode refers to the way an end-node sends and receives data on the
network. An end-node can operate in either half- or full-duplex mode,
depending on its capabilities. An end-node that is operating in half-duplex
mode can either send data or receive data, but it cannot do both at the same
time. An end-node that is operating in full-duplex mode can send and receive
data simultaneously. The best network performance is achieved when an end-
node can operate at full-duplex, since the end-node is able to send and receive
data simultaneously.
The AT-MC1004 and AT-MC1005/x Series Gigabit Ethernet Media Converters
operate in full-duplex mode only. The media converter can operate with end-
nodes capable of either full-duplex mode or that can auto-negotiate the duplex
mode. However, it is important to remember that the two end-nodes connected
to the ports on the media converter must be able to operate in full-duplex
mode.
External AC/DC Power Adapter
An external AC/DC power adapter is included with the media converter for
desktop operation (see Figure 3). 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,
1000 mA.
Note
The power adapter is not used if you install the media converter in an
AT-MCR12 chassis.

Network Topologies
The AT-MC1004 and AT-MC1005/x Series Gigabit Ethernet Media Converters
can be used in two different network topologies: standalone and back-to-back.
These network topologies are described below.
Standalone Topology
A standalone topology uses only one media converter between the end-nodes.
Figure 4 illustrates a standalone topology that uses two AT-MC1005/1 media
converters to interconnect three remote campuses. Campus 1 has an
AT-8224XL switch with two AT-A15/LX expansion modules. The modules,
which provide a connection of up to 10 kilometers (6.2 miles), are connected to
the 1000Base-LX ports on the media converters. The 1000Base-T ports on the
media converters are connected to the AT-A14 expansion modules in the
AT-8216FXL/MT switches at Campus 2 and Campus 3.

Back-to-Back Topology
In some network configurations you may want to interconnect two media
converters in what is referred to as a back-to-back topology. In this topology,
the media converters not only extend the distance of your network but also
convert the fiber optic cable from twisted pair to fiber optic and back again.
Figure 5 illustrates one AT-8216FXL/MT switch with an AT-A14 expansion
module at each campus. The switches are interconnected by two AT-MC1005/3
media converters. The 1000Base-T ports on the media converters are
connected to the AT-A14 expansion modules in the switches, while the
1000Base-LX ports on the media converters are directly connected together.
Note
When using two media converters back-to-back, you must set both
converters to the same mode (ie. the first media converter is set to
MissingLink mode; then the second converter must also be set to
MissingLink mode.
