Product Overview
The AT-MC102XLPCI & AT-MC102XLPCIe 100Mbps Media Converters
products are designed to connect with the PCI bus in a computer. The
MC102XLPCI is designed for a PCI card slot and the MC102XLPCIe is
designed to interface with a PCI Express card slot. The specifications for
these two products along with their respective installation instructions are
identical with one exception - the physical connector is different between
the two products to conform with the different dimensions of the PCI and
PCI Express connectors.
Note
For simplicity in the rest of this manual, the AT-MC102XLPCI & AT-
MC102XLPCIe 100Mbps Media Converters will be referred to as AT-
MC102XLPCI Media Converter.
The AT-MC102XLPCI Media Converter is designed to connect a copper
Ethernet medium with a fiber Ethernet medium. A common application for
this product is providing an interconnection between a computer's network
copper port and a fiber network infrastructure.

Key Features
The AT-MC102XLPCI Media Converter features a 100Base-TX twisted-
pair port and an 100Base-FX fiber optic port. The twisted-pair port has an
RJ-45 connector and a maximum operating distance of 100 meters (328
feet). The fiber optic port has a dual SC connector and a maximum
operating distance of 2 kilometers (1.2 miles).
This media converter operates at 100 Mbps and is configured from the
factory for Auto-Negotiation mode.
The AT-MC102XLPCI Media Converter is designed to be installed in a
PCI bus slot of a PC and does not require any software configuration or
management.
An AT-MC102XLPCI Media Converter is illustrated in Figure 1.
Figure 1. AT-MC102XLPCI Media Converter
The AT-MC102XLPCI Media Converter has the following key features:
❒100Base-TX twisted-pair port Half- or full-duplex operation - See
Figure 1.
❒100Base-FX fiber optic port - See Figure 1.
❒See Status LEDs on page 17 for more information.
❒See Auto MDI/MDIX on page 18 for more information.
❒See Auto-Negotiation on page 19 for more information.
❒See MissingLink & Link Test Features on page 21 for more

Status LEDs
The AT-MC102XLPCI Media Converter has two status LEDs associated
with the 100Base-TX twisted-pair port and the 100Base-FX fiber optic port.
The location of these LEDs is shown in Figure 2.

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 twisted-
pair 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.

Auto-Negotiation
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 twisted-
pair ports to operate in Full Duplex mode.
Note
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.

Note
Although it is not marked on J4, Pin 2 is positioned between pins 1
and 3.
Note
If you choose to remove the jumper, Allied Telesis recommends that
you re-install the jumper on the center pin (2) only, 90 degrees from
the pins 1 and 3 so that it does not get lost.
