Introduction
The AT-MMC1000/SP Mini Switching Media Converter as shown in
Figure 1 is equipped with to a twisted pair port and SFP slot to allow
enterprises to connect copper networks to fiber networks and extend the
distance of these networks by interconnecting LAN devices physically
separated by large distances.

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 44.
Note
For twisted-pair port cabling specifications, refer to Table 2 on
page 31.
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 25.
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.

AT-MMC1000 Mini Switching Media Converter Installation Guide

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.
External AC/DC
Power Adapter
An external AC/DC power adapter is included with the media converter for
standalone operation. The power adapter supplies 12 VDC to the media
converter. Allied Telesis supplies a UL approved safety compliant AC
power adapter for the 120 and 240 VAC versions with a regulated output
of 12 VDC. The power required for the media converter is 12 VDC,
200 mA and the power adapter complies with LPS/PS2 requirements.
Note
The media converter power receptacle has a twist-and-lock barrel
which is locked by turning the power cord clockwise one-quarter
turn.
