Introduction
The MMC2000/200 Series Mini Switching Media Converters are designed
to extend the distance of your network by interconnecting LAN devices
that are physically separated by large distances.
The MMC2000/200 Series Mini Switching Media Converters include the
following models:
AT-MMC2000/SC
AT-MMC2000/ST
AT-MMC2000/SP
AT-MMC2000/LC
AT-MMC2000LX/LC
AT-MMC2000LX/SC
AT-MMC200/SC
AT-MMC200/ST
AT-MMC200/LC
AT-MMC200LX/SC
AT-MMC200LX/ST
Features Here are the key features of the MMC2000/200 Series converters:
The media converter provides a smaller-sized space-saving
alternative that allows enterprises to connect copper networks to
fiber networks, offering a cost-effective method for integrating
fiber-optic cabling into a 10/100/1000 or 10/100 UTP environment.
See Table 1 for the specifications of the ports that the media
converter is equipped with.

12 VDC external wall-mount AC power adapter
The AT-MMC2000LX/nn and AT-MMC200LX/nn models operate
with a single-mode fiber optic cable.
The fiber port of the AT-MMC2000/nn model has a maximum
operating distance of 500m.
The fiber port of the AT-MMC200/nn model has a maximum
operating distance of 2km.
The fiber port of the AT-MMC2000/200LX/nn model has a
maximum operating distance of 20km.
Note
The parameter nn can be SC, ST, SP, or LC.
Note
For more details, see “Fiber-Optic Port Specifications” on page 54.

Note
For the AT-MMC2000/SP model, you must purchase the SFP
transceiver separately. The maximum operating distance of the AT-
MMC2000/SP is dependent on the specific SFP module. For a list of
supported transceivers, contact your Allied Telesis distributor or
reseller.
Twisted-Pair Port Here are the basic features of the twisted-pair (copper) port:
IEEE 802.3u Auto-Negotiation compliant
Auto MDI/MDI-X
100 meters (328 feet) maximum operating distance
RJ45 connector
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 52.
Note
For twisted-pair port cabling specifications, refer to Table 3 on
page 34.
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.
Auto-Negotiation
or 100 Mbps Full-
Duplex Mode
You can set the twisted-pair port to 100 Mbps full-duplex mode or Auto-
Negotiation mode using the PORT 1 (right) DIP switch on the rear panel.
See Figure 9 on page 23.
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.

MMC2000/200 Series Mini Switching Media Converter Installation Guide
19
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.
