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 full-

duplex operation.

Chapter 1: Overview

2

The AT-MC10x Series media converters can be installed on a desktop or

in an AT-MCR12 chassis, AT-WLMT-10 Wallmounting Bracket, or

AT-TRAY4 Rackmount Tray. The AT-MC10x Series media converters are

easy to install and do not require any software configuration or

management.

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)/MissingLink

TM

(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.

Chapter 1: Overview

8

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 end-

node 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.

AT-MC10x Series Media Converters Installation Guide

9

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 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 one situation where it may be necessary to disable the Auto-

Negotiation 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 end-

nodes.

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 half-

duplex operation, thus eliminating the mismatch in duplex modes

between the end-nodes.

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 Auto-

Negotiation, 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.
