AT-MCF106xx and AT-MCF112xx Multichannel Ethernet Media Converters

The Ethernet AT-MCF106xx and the AT-MCF112xx 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, whic h
previously were difficult to interconnect, are easily interconnected to form one
integrated network.

The ports on the media conv erters 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, wh ile the AT - M CF 1 12xx unit
features twelve channels, giving you twelve i n dividual 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) cab le.

The multichannel 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.

Twisted Pair and Fiber Optic Ports

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 Multichannel Media
Converter has twelve channels.

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-thro u gh cable. Connecting a workstation to a tw isted pair port
requires a crossover cabl e.

100Base-FX Fiber Optic Ports.

The 100Base-FX fiber optic ports operat e at 100
Mbps and, depe nding on the model, operate with multimode or single-mode
fiber optic cabling.

The type of connector on the fiber optic ports w ill depend on the system model
you purchased. Ref er to Tabl e 1 on page 2 fo r the avai lable typ es of co nnect ors.

AT-MCF106xx and AT-MCF112xx Installation Guide

Port LEDs

Each channel on the media converter has a series of LEDs that you can use to
monitor the status of the ports of the channel. 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 traffi c.

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 multichannel media
converter (see Figure 4). The AT -MCF106xx system has one Link Test switch
which is used to test all six fiber optic ports on the unit. The AT-MCF112xx
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.

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 “Verifying the
Installation” on page 19 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 recommende d that the Link Test switch be set to the Normal
position during normal network operations.

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. Yo u m us t r eset the un it af t er a po wer disr up tion or when eve r a
general power failure status is observe d.

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 othe r. When a chan nel detects a problem with one of the
ports, such as the loss of connecti on to a node, the channel shuts down th e
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.
