AT-MC103LH Fast Ethernet Media Converters
The AT-MC1 01XL and AT-MC1 02XL conve rt IEEE 802.3u 100Base-TX to
100Base-FX multimode Fast Ethernet network connections. The
AT-MC103XL and AT-MC103LH convert to FX single mode. The 100Base-FX
interfaces are available in ST or SC connectors for multimode fiber cabling.
For single mode cab ling, the 100Base-FX is av ailable in SC connec tors only.
The 100Base-TX interface uses an RJ45 shielded connector.

Installation Guide
LEDs
The PWR LED in the upper right corner of the front panel lights when the
media converter is receivin g powe r. Status LEDs are located on the front
panel next to each port and described in Table 1.

MDI/MDI-X Switch
The MDI/MDI-X (Med ia Dependent Interf ace/Media Depend ent Interface wit h
Crossover) switch, located on the front panel, is a straight-through or
crossover cable selection switch. It enables the RJ45 port to be connected to a
repeater or DTE device without using a special crossover cable. The default
position of the swi tch is MDI -X, which means you c an connec t the RJ4 5 port to
a workstation or to any other DTE device using a straight-through cable.
NML/LNK TST Switch
The NML/LNK TST (Normal/Link Test) switch, located on the front panel,
establishes a fiber/twisted pair link in the test position.
The default position of the switch is IN, which is the normal (NML) operating
mode and enables the MissingLink feature. With the switch in the OUT or
Link Test mode (LNK TST) position, the MissingLin k feat ure is disabled and
the optical transmitter TX is forced on. The NML LED lights when the NML/
TST LNK switch is in the default (IN) operating position.
Using the Link Test mode does not interfere with the media converter’ s
Note
ability to pass network t raffic.

Auto-Negotiation
The 100Base-TX ports participate in IEEE 802.3u Standard auto-negotiation
with its local link partner.
End stations used with the media converter must operate in the same
Note
duplex mode (either both full-duplex or both half-duplex).
Note
The media converters have an additional feature, allowing the unit to
operate in 100 Mbps half-duplex mode. Certain applications require this
mode, for exampl e, two media converters installed in a bac k -t o-b ack
configuration (fiber-to-fiber) which are attached to unmanaged repeaters
and/or switches that auto-negotiates with the other. For instructions on
how to set up the media converter for this application, contact Allied
Telesyn Technical Support.
MissingLink
MissingLink gives the host (router, server, switch) attached to each end of the
converter critical information about the status of the other (remote) segment
link. If either link fails, the converter interacts with both hosts, making each
instantly aware of the link fault. Either host can then execute
preprogrammed, redundant transmission path selection.
External AC-DC Power Adapter
An external AC-to-DC power adapter is included with the fast switch for
standalone operation (see Figure 5). The power adapter supplies 12 volts DC
to the media converter. Allied Telesyn supplies an approved safety compliant
AC power adapter for the 120 and 240 V AC versions with an unregulated
output of 12 V DC at 1 A. The power required for the media converter is 12 V
DC, 500 mA.

Standalone Installation
1. Remove all equipment from the package and store the packaging in a safe
place
2. Attach the four rubber feet to the base of the unit, placing one rubber foot
in each corner. For rack-mount installation, do not attach the four rubber
feet.
3. Plug the AC-DC power adapter into an appropriate AC power outlet and
insert the power plug into the DC receptacle located on the rear panel.
