Chapter 1: Product Overview
Auto MDI/MDIX
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 twistedpair port on a switch or hub is usually MDI-X.
The AT-MC102XLPCI Media Converter features 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 PC, 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 to any type of device.
18
Auto-Negotiation
Note
AT-MC102XLPCI 100Mbps Media Converter Installation Guide
The Auto-Negotiation feature is used to automatically determine a
common duplex mode between the twisted-pair port and its link partner.
This feature is enabled at the factory and is compatible with the IEEE
802.3u specification.
The 100FX port usually operates in Full Duplex mode. The goal of the
Auto-Negotiation feature is to avoid a duplex mismatch between the
copper and fiber ports of the AT-MC102XLPCI by ensuring that the
twisted-pair port and its link partner are also configured to operate in Full
Duplex mode. In most configurations, the link partner of the twisted-pair
port is configured for Auto-Negotiation by default so the Auto-Negotiation
feature of the MC102XLPCI also needs to also be activated (factory
default configuration). If the twisted-pair link partner’s port is set to Fixed
Full Duplex mode, then the MC102XLPCI should be configured with the
Auto-Negotiation disabled. In both cases, these settings allow the twistedpair ports to operate in Full Duplex mode.
If the twisted-pair link partner’s port is set to Fixed Half Duplex
mode, a duplex mismatch can occur with the fiber port assuming the
fiber port is operating in Full Duplex mode. This situation can result
in significant degradation of Ethernet traffic throughput. To avoid this
issue, ensure that the twisted-pair link partner’s port is configured for
either Auto-Negotiation or Fixed Full Duplex when the fiber port is
operating in Full Duplex mode.
The location of the jumper (J4) is shown in Figure 3. The Auto-Negotiation
configuration and jumper pin positions for jumper J4 are given in Table 2.

MissingLink & Link Test Features
The MissingLink & Link Test jumper (J5) on the PC board is configured at
the factory with the MissingLink feature enabled and Link Test disabled.
This section contains the following topics:
❒ MissingLink Feature
❒ Link Test Feature
❒ Configuring MissingLink & Link Test Features on page 22
AT-MC102XLPCI 100Mbps Media Converter Installation Guide
MissingLink
Feature
The MissingLink feature enables the fiber optic and twisted-pair ports on
the media converter to pass the “Link” status of their connections to each
other. The AT-MC102XLPCI is configured for MissingLink at the factory
with pin 1 and pin 2 connected of jumper J5 (see Figure 4). When the ATMC102XLPCI detects that an active link has gone down on one of its
ports, it shuts down the link to its opposite port. The result is that the ATMC102XLPCI notifies the end node connected to the opposite port by
setting its link to go down.
This type of behavior is a form of network monitoring and fault notification
for the network device connected to the opposite port of the ATMC102XLPCI. Some network devices can be configured to recognize that
the loss of connection on a port and take a specific action in response to
this event. For example if the end node is a managed switch, it can be
configured to choose a redundant path as an alternative data path and/or
send out a trap to a network management station so that the network
administrator can be notified of the problem.
For example, if the twisted-pair cable to the 100Base-TX port on the media
converter were to fail and the link went down, the AT-MC102XLPCI 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. When the failed Ethernet path is repaired and the link is
re-established, then the AT-MC102XLPCI re-establishes the link on its
opposite port.
Link Test Feature The Link Test mode provides a method of testing 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. This test allows you to
focus on the port and end-node where the problem resides.

Twisted-Pair
LED
If the LINK LED for the twisted-pair port is OFF, do the following:
1. Verify that the PC is powered ON and has booted up successfully.
2. Check that the end-node connected to the port is powered ON and is
operating properly.
3. Check that the twisted-pair cable is securely connected to the twistedpair port on the media converter and on the remote end-node.
4. Make sure that the twisted-pair cable does not exceed 100 meters
(328 feet) and that you are using Category 5 or better Ethernet cable.
5. Verify that both end-nodes connected to the media converter are
operating at 100 Mbps and Auto-Negotiation.
6. If you are still experiencing problems , refer to “Contacting Allied
Telesis” on page 13 or visit our web site at alliedtelesis.com for

Fiber Port LED If the LINK LED for the fiber optic port is OFF, do the following:
1. Verify that the PC is powered ON and has booted up successfully.
2. Verify that the end-node connected to the port is powered ON and is
operating properly.
3. Check that the fiber optic cable is securely connected to the fiber optic
port on the media converter and on the end-node.
4. Verify that the end-nodes connected to the media converter are
operating at the same speed. Both must be operating at 100 Mbps.
5. Make sure that the cable connected to the media converter’s receiver
port (RX) is connected to the end-node’s transmitter port (TX) and that
the media converter’s transmitter port (TX) is connected to the endnode’s receiver port (RX).

Overview
6. Test the attenuation on the fiber optic cable to ensure that it does not
exceed acceptable values. Refer to “RJ-45 Twisted-Pair Port
Specifications” on page 38 for more information.
7. Verify that you are using the appropriate type of fiber optic cable and
that you have not exceeded the maximum operating distance. For
maximum operating distances and cable types, refer to “Fiber Optic
Port Specifications” on page 39.
8. Check that the operating specifications (e.g., wavelength and
maximum operating distance) of the fiber optic port on the end-node
are compatible with the operating specifications of the fiber optic port
on the media converter. Refer to “Fiber Optic Port Specifications” on
page 39 for more information.
9. If you are still experiencing problems , refer to “Contacting Allied
Telesis” on page 13 or visit our web site at alliedtelesis.com for
support information.
Link Test To check hardware reliability of the media converter, perform the following
procedure:
1. Power OFF the PC chassis where the media converter is installed.
1. Connect the RJ-45 twisted pair port to a 100Base port on an endnode, such as an Ethernet switch, and power ON the end-node.
2. Using a tested and good fiber patch cable, attach the matching ends of
the fiber cable to the transmit (TX) and receive (RX) connectors of the
media converter and the opposite ends to a second end node with a
compatible 100 MB fiber port. Power ON the end-node.
3. Configure the media converter for Link Test and re-install the media
converter in the PC. See “Configuring MissingLink & Link Test” on
page 28 for more information.
4. Power ON the PC chassis where the media converter is installed.
5. Verify that the PC is powered ON and has booted up successfully.
6. Verify that the LINK LED on both the twisted pair and fiber optic ports
are green.
7. If the LEDs are green, the unit is working properly and there is a
problem elsewhere on the segment.
