AT-MCF6xx and AT-MCF12xx Multichannel Ethernet Media Converters

The Ethernet AT-MCF6xx and the AT-MCF12xx 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 10Base-T and 10Base-FL technologies, enable
you to quickly and easily interconnect the nodes in your network to distances
of 2 kilometers (1.24 miles) to 15 kilometers (9.3 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 conv erters are grouped into pairs, referred to as
“channels,” with each pair consisting of a 10Base-T twisted pair port and a
10Base-FL fiber optic port. Each channel functions as an independent media
converter. The Ethernet AT-MCF 6xx unit features six channels, providing yo u
with six individual media converters, while the AT-MCF12xx unit features
twelve channels, giving you twelve individual media converters.

The twisted pair ports are designed to operate with Category 3 or better
cabling at a speed of 10 Mbps. The fiber optic ports also operat e at a speed of
10 Mbps and are ava ilabl e in a vari ety o f conne ctor t ypes. Th e fibe r optic po rts
support IEEE stan dard Multimode Fiber (MMF) or Single-Mode Fiber ( SMF)
cable.

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.

and thus operate at 10 Mbps only. The ports require Cat egory 3 or bett er
cabling and allow fo r a distance of 100 meters (328 feet).

The devices that you connect to the twisted pair ports must operate at
10 Mbps. To connect a switch, hub, or router to a twisted pair port requires a
straight-through cable. To connect a workstation to a twisted pair port
requires a crossover cabl e.

10Base-FL Fiber Optic Ports.

The 10Base-FL fiber optic ports operate at 10 Mbps
and, depending on the model, function 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. Refer to Table 1 on page 2 for a list of the available types of
connectors.

AT-MCF6xx and AT-MCF12xx Instal lat io n 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-MCF6xx system has one Link Test switch
which is used to test all six fiber optic ports on the unit. The AT-MCF12xx 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.

The multichannel media converter will not pass network data when the
Link Test switch is in the Link Test position. For normal network
operations, the switch must be set to the Normal setting.

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-MCF6xx 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-3714FXL/SC Ethernet switch. If the fiber optic cable of the AT-3714FXL/
SC 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-MCF6xx unit notifies the AT-8224XL Ethernet switch that the connection
to the AT-3714FXL/SC Ethernet switch has been lost. Had the failure started
with the twisted pair cabling, the MissingLink feature would have dropped
the link to the fiber optic port.

AT-MCF6xx and AT-MCF12xx Instal lat io n Guide

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-3714FXL/SC 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.

Duplex Mode

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 w hen a
node can operate at full-duplex, since the node is able to both send and receive
data at the same time.

The AT-MCF6xx and AT-MCF12xx Multichannel Media Converters are
transparent to the duplex mode of the nodes that are connected to their ports.
That is, the units can operate with nodes operating at either half-duplex or
full-duplex mode. However, the two nodes that are connected to the same
channel on the media converter must operate with the same duplex mode.

For example, assume that you connected a node operating at half-duplex to
the twisted pair port of a c hannel on the medi a conv erter a nd a node operati ng
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 have to be changed to half- d u p lex.

7

Optional Redundant Power Supply Slot

The rear panel of the multichannel 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 the 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.” Thi s me ans th at s hou ld eithe r p owe r suppl y fai l, t he fail ed uni t ca n
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 conver ter from operational failur e sh ould a power circu i t fail.

Note

A redundant power supply is strongly recommended for the
AT-MCF12xx Multichannel Media Converter to help avoid a “single
point of failure” to as many as twelve links.

Power Inlet

The unit does not have an O N /O FF power switch. Power is ap plied to and
removed from the system by connecting and disconnecting the power cable.

Warning
Power cord is used as a disconnection device:

equipment, disconnect the power cord. !10

Network Topology

The value of the AT-MCF6xx and AT-MCF12xx 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 7 illustrates an example of a network that incorporates a model
AT-MCF6SC unit to interconnect dispersed network devices. The model has
SC type fiber optic connec to rs 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-MCF6SC media converter. Fiber optic cabling
from the AT-MCF6SC unit co nnects the media convert e r to the switches,
hubs, and workstation that comprise the network.

Installing the Multichannel Media Converter

The following sect ions explain how to install the unit onto your network. The
unit can be installed as a standalone system (such as on a desk) or in a
standard 19-inch rack.

Selecting a Site for the Multichannel Media Converter

Be sure to observe the following requirements when choosing a site for your
media converter:

❑

Select a site that is dust-free and moisture-free.

❑

Do not block the ventilation openings on the unit. The site should
allow for proper heat dissipation from and adequate ventilation
around the media converter.

❑

Be sure that the site will allow you to easily access the twisted pair
cables, fiber cables, and power cord.

❑

Use dedicated power circuits or power conditioners to supply reliable
power to the unit.

❑

Keep the media converte r and twisted pair cabl ing away fro m sources
of electrical noise, such as radios, electric motors, transmitters,
broadband amplifiers, power lin es, and fluorescent fixtures.

Planning the Installation

Refer to the following guidelines when planning the installation of the medi a
converter:

❑

All nodes connected to the ports on the media converter must operate
at 10 Mbps.

❑

The nodes connected to a same channel on the media converter must
operate with the same duplex mode, either half-duplex or full-duplex.
For example, you cannot connect a node operating at half-duplex to a
twisted pair port and another node operating at full-duplex to the fiber
optic port of the same channel on the media converter.

❑

Refer to Table 2 for the twisted pair cabling specifications.

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. 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.

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
redundant power supply, if installed , are operatin g.

4. Set the Link Test switch to the Test position. If you are installing an
AT-MCF12xx unit, set both Link Test switches to the Test position.

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

Note

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

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

19

6. If one or more of the F-LNK LEDs for the fiber optic port s are not lit, go to
the section “Troubleshooting” on p age 21.

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

Note

The multichannel media converter will not pass network data when the
Link Test switch is in the Link Test position. For normal network
operations, the switch must be set to the Normal setting.

The multichann el media converter is now ready for normal network
operations. For info rmation on operating the unit and on the LEDs, refer to
the next section, “Ope rating the Multich a nnel Media Converter.”

Operating the Multichannel Media Co nverter
