The AT-PC2000/SP has a plug-in SFP cage fiber connection.
1000-X and 100-FX modules are supported.
Note
For the AT-PC2000/SP, you must purchase the SFP transceiver
separately. For a list of supported transceivers, contact your Allied
Telesis distributor or reseller.
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.

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 (as shown in Figure 5 on page 23), the fiber PORT 1 L/A
LED blinks slowly while the fiber port’s link is turned OFF. The copper
PORT 2 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 (as shown in Figure 4),
then the copper PORT 2 L/A LED would blink slowly, and the fiber PORT 1
L/A LED would turn OFF.
SML Example Scenarios
Following are example scenarios with one SML enabled media converter
connected between two end nodes.

The port has a maximum operating distance of 100 meters (328 feet). For
twisted-pair port cabling specifications, refer to Table 2 on page 34.
You can set the twisted-pair port to 100 Mbps full-duplex mode or Auto-
Negotiation mode using DIP switch 2 (middle) of the three DIP switches on
the rear panel. See Figure 9 on page 24.
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.
Note
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.

Troubleshooting
This chapter contains information on how to troubleshoot the media
converter if a problem occurs.
Note
For further assistance, please contact Allied Telesis Technical
Support at www.alliedtelesis.com/support.
Problem 1: The POE POWER LED on the media converter is off.
Solutions: The PoE port on the unit is not supplying power. Try the
following:
Verify a PoE device is plugged into the port.
The PoE device may be faulty: try using another PoE device.
Problem 2: The POE FAULT LED on the media converter is lit red.
Solution: The PoE device is attempting to draw over 30 W. Use a PoE
device that does not draw over 30 W.
Problem 3: The SYS LED on the media converter is off.
Solution: An internal component on the unit is damaged or not working
properly. Try power cycling the unit. If power cycling does not clear the
fault, return the unit to Allied Telesis.
Problem 4: The SYS LED on the media converter is blinking slowly.
Solutions: An error is present on the unit. Try power cycling the unit.
If an AT-PC2000/SP unit, a transmit fault may be occurring on the SFP
module. 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.
Problem 5: The twisted-pair port on the media converter is connected to
an end node, but the copper port’s PORT 2 L/A LED is off.
Solutions: The port is unable to establish a link to an end node. Try the
following:
Chapter 3: Troubleshooting
50
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 6: The PORT 1 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.
On media converters other than the AT-PC2000/SP: 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).
On the AT-PC2000/SP, check that the SFP module is fully inserted
in the slot.
PC2000/200 Series Switching Media Converter Installation Guide
51
On the AT-PC2000/SP, 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 wavelength between the media converter and end
node matches, and the media converter fiber port is connected to a
multi-mode (not single-mode) port on the end node.
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 7: 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.

Appendix B
Cleaning Fiber-Optic Connectors
This appendix contains the following sections:
“Introduction”
“Using a Cartridge-Type Cleaner” on page 58
“Using a Swab” on page 60
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.
Figure 25 shows the ferrule in an SC connector.

Using a Swab
Specially treated swabs, or stick cleaners, are available for cleaning inside
connector adapters or hard-to-reach ferrule tips. These swabs, often
referred to as “lint-free” or “alcohol-free” swabs, shown in Figure 29, are
available from many vendors. Stick cleaners are available in both 2.5 mm
and 1.25 mm sizes for use on SC and MU connectors, respectively.
