converters, which can be deployed outdoors and in hash environments.
Figure 1 shows the AT-IMC2000TP/SP model.
Figure 1. AT-IMC2000T/SP Media Converter
Key Features The IMC2000/200 series media converter has the following key features:
Tolerance to harsh industrial environments (See “Environmental
Specifications” on page 49)
DIN rail mountable
Wall mountable
Note
To install the media converter on the wall, you must obtain the

DC power connector
IEEE 802.3u Auto-Negotiation compliant on the copper port
Auto-Negotiation or 100 Mbps full-duplex mode on the copper port
Auto MDI/MDI-X on the copper port (See “Auto MDI/MDI-X” on
page 13)
One SC or SFP fiber optics connector
Chapter 1: Overview

One twisted-pair port (See “Twisted-Pair Port” on page 14)
Far end fault on 100Mb fiber port
Power over Ethernet (PoE) (IEEE 802.3at 30watt)
Pre-standard 60watt PoE (LTPoE++)
10Kbyte Jumbo packets
Smart Missing LinkTM(SML) (See “Smart MissingLink™ (SML)” on
page 18)
Table 1 shows the specifications of the ports and PoE for each model.
Auto MDI/
MDI-X
An RJ45 twisted-pair port on a 100 Mbps Ethernet network device can
have one of two possible wiring configurations: MDI or MDI-X. The RJ45
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 media converter features Auto MDI/MDI-X. The twisted-pair 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, regardless of the wiring
configuration of the port on the device.

DIP Switches The media converter is equipped with the DIP switches. Figure 2 shows
the DIP switches on the media converter.
Figure 2. DIP Switches
To configure the media converter, use the following DIP switches:
SML - Turn on or off the SML feature.
FORCE 100FD - Select Auto Negotiation or set the port speed for
100Mbps in full-duplex mode.
REMOTE PoE CONTROL - Activate or deactivate remote PoE which
allows you to remotely power cycle your PoE device.
Note
The only AT-IMC2000TP/SP, AT-IMC2000TP/SC, and
AT-IMC200TP/SC models are equipped with the Remote PoE
Control DIP switch. DIP switch 3 is not used for the other models.
DC Power The IMC2000/200 series media converter is equipped with the DC power
connector.
Twisted-Pair Port The twisted-pair port features an eight-pin RJ45 connector that uses four
pins at 10 or 100 Mbps and all eight pins at 1000 Mbps. For the port
pinouts, see “RJ45 Connector and Port Pinouts” on page 50.
The port has a maximum operating distance of 100 m (328 feet). For
twisted-pair port cabling specifications, refer to Table 3 on page 27.
Auto-Negotiation
or 100 Mbps
Setting
You can set the twisted-pair port to 100 Mbps full-duplex mode or Auto-
Negotiation mode using the DIP switch See Figure 2 on page 14.
When this DIP switch is in the FORCE 100 F/D (up) position, the
twisted-pair port is forced to 100 Mbps full-duplex mode, and Auto
Negotiation is disabled
When in the AUTO NEG (down) position, the twisted-pair port
operates in Auto-Negotiation mode.
Chapter 1: Overview
15
Caution
100 Mbps full-duplex mode should not be used unless absolutely
necessary because forcing 100 Mbps full-duplex in most
applications is likely to cause a duplex mismatch, in turn, causing
poor network performance. 100 Mbps full-duplex mode should only
be used when the link partner is already forced to 100 Mbps full-
duplex operation, and Auto-Negotiation is disabled on the link
partner. In this specific case, using Auto Negotiation on the media
converter would result in a duplex mismatch.

Smart MissingLink™ (SML)
If one of the Ethernet connections to the media converter loses link, the
Smart MissingLink™ (SML) feature allows you to determine which port still
has a valid connection and which port requires troubleshooting. The value
to this type of network monitoring and fault notification is that you can
quickly determine which media converter port has failed and troubleshoot
the specific area where the problem is occurring.
When the media converter detects a loss of connection on one of the
ports, the port’s L/A LED is turned off. At the same time, the media
converter causes the opposite port’s L/A LED to blink while simultaneously
turning OFF that port’s Ethernet connection to its end node. This occurs
even though the properly operating port had a valid connection before the
failure occurred: The reason for this is so that its end node is notified that
the data path has been compromised, and immediate action is required.
For example, if the network connection to the media converter’s twisted-
pair port fails, the FIBER P2 L/A LED blinks slowly while its link is turned
OFF. The COPPER P2 L/A LED is turned OFF, indicating a failed
connection on the twisted-pair port. If the failure had started with the fiber-
optic cabling, then the COPPER P2 L/A LED would blink slowly, and the
FIBER P2 L/A LED would turn OFF.

Selecting a Site for the Media Converter
Observe the following requirements when choosing a site for your media
converter:
If you are installing the media converter on a table, verify that the
table is level and secure.
The site should provide for easy access to the ports on the front of
the media converter. This will make it easier for you to connect and
disconnect cables, as well as view the media converter’s LEDs.
Air flow around the unit and through its vents on the side should
not be restricted so that the media converter can maintain
adequate cooling.
Do not place objects on top of the media converter.
Do not expose the media converter to moisture or water.
You should use dedicated power circuits or power conditioners to
supply reliable electrical power to the network devices.
Chapter 2: Installation
27
Planning the Installation
Be sure to observe the following guidelines when planning the installation
of your media converter.
On the AT-IMC2000 media converter, the end node connected to
the fiber connector on the media converter must operate at 1000
Mbps, except for the AT-IMC2000/SP when using a 100 Mbps SFP
module.
On the AT-IMC200 media converters, the end node connected to
the fiber connector on the media converter must operate at 100
Mbps.
The two end-nodes connected to the ports of the media converter
must operate with the same duplex mode, either half- or full-
duplex. The twisted-pair port on the media converter can operate in
either mode with Auto Negotiation enabled.
The media converter connects a copper unshielded twisted pair
(UTP) network cabling to a fiber optic cabling, which allows two
network devices, such as a network adapter card, repeater, switch,
media converter, router, camera, or access point, across long
distances.
The twisted-pair port has a maximum operating distance of 100
meters (328 feet).

required levels for the AT-IMC2000/200 series media converter.
Solution: An internal component on the unit is damaged or not working
properly. Try the following:
Power cycling the unit.
If power cycling does not clear the fault, return the unit to Allied
Telesis.
Problem 2: The SYSTEM LED on the media converter is blinking slowly.
Solution: An error is present on the unit. Try the following:
Power cycling the unit.
If it is an AT-IMC2000TP/SP or AT-IMC2000T/SP unit, a transmit fault may
be occurring on the SFP module, or the SFP module itself may be causing
some other errors. The media converter will try to clear this error, but if the
error persists, try the following:
Remove and re-seat the SFP module.
Try a different SFP module.
Verify the SFP module is the correct type for your application.
IMC2000/200 Series Media Converter Installation Guide
46
Problem 3: The twisted-pair port on the media converter is connected to
an end node, but the copper port’s L/A LED is off.
Solutions: The port is unable to establish a link to an end node. Try the
following:
Verify that the end node connected to the twisted-pair port is
powered on and is operating properly.
Verify that the twisted-pair cable is securely connected to the port
on the media converter channel and to the port on the remote end-
node.
Verify that the port is connected to the correct twisted-pair cable.
This is to eliminate the possibility that the port is connected to the
wrong end-node, such as a powered-off device.
Try connecting another end node to the twisted-pair port with a
different cable. If the twisted-pair port is able to establish a link,
then the problem is with the cable or the other end-node.
Verify that the twisted-pair cable does not exceed 100 meters (328
feet).
Verify that the end node connected to the media converter is
operating at the same speed.
Verify that you are using the appropriate category of twisted-pair
cable: Category 3 or better for 10 Mbps operation and Category 5
and Category 5E for 100 and 1000 Mbps operation.
Note
A 1000Base connection may require 5 to 10 seconds to establish a
link.
Problem 4: The FIBER port’s L/A LED for the fiber-optic port is off.
Solutions: The fiber-optic port on the transceiver is unable to establish a
link to an end node. Try the following:
Verify that the end node connected to the fiber-optic port is
operating properly.
Verify that the fiber-optic cable is securely connected to the port on
the media converter channel and to the port on the remote end-
node.
Verify that the end node connected to the media converter is
operating at the same speed.
Verify that the media converter’s transmitter port (TX) is connected
to the end node’s receiver port (RX) and that the media converter’s
receiver port (RX) is connected to the end node’s transmitter port
(TX).
Chapter 4: Troubleshooting
47
On the AT-IMC2000TP/SP or AT-IMC2000T/SP unit, check that
the SFP module is fully inserted in the slot.
On the AT-IMC2000TP/SP or AT-IMC2000T/SP unit, verify that the
operating specifications and wave lengths of the fiber-optic port on
the SFP transceiver and the remote end-node are compatible.
Verify that the correct type of fiber-optic cabling is being used.
Verify that the port is connected to the correct fiber-optic cable.
This is to eliminate the possibility that the port is connected to the
wrong remote end-node, such as a powered-off device.
Try connecting another end node to the fiber-optic port using a
different cable. If the port is able to establish a link, then the
problem is with the cable or with the other end node.
If the remote end-node is a management device, use its
management firmware to determine whether its port is enabled.
Test the attenuation on the fiber-optic cable with a fiber-optic tester
to determine whether the optical signal is too weak (sensitivity) or
too strong (maximum input power).
Problem 5: Network performance between the twisted-pair port on the
media converter and an end node is slow.
Solution: There might be a duplex mode mismatch between the port and
the end node. This occurs when a twisted-pair port using Auto Negotiation
is connected to a device with a fixed duplex mode of full duplex. If this is
the cause of the problem, adjust the duplex mode of the port on the end
node or on the media converter so that both ports are using the same
duplex mode.

Cleaning Fiber-Optic Connectors
This appendix contains the following sections:
“Introduction”
“Using a Cartridge-Type Cleaner” on page 54
“Using a Swab” on page 56
This appendix describes how to clean fiber-optic connectors.
Introduction
The fiber-optic connector consists of a fiber-optic plug and its adapter. The
end of the fiber-optic cable is held in the core of the ferrule in the plug.
Light signals are transmitted through the core of the fiber. Even minor
smudges, or dirt, on the end face of the fiber (completely invisible to the
naked eye) can disrupt light transmission and lead to failure of the
component or of the entire system. Therefore, it is of utmost importance to
clean all fiber-optic connectors before use.
