AT-MC103LH Fast Ethernet Media Converters 

The AT-MC101XL and AT-MC102XL convert 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 cabling, the 100Base-FX is available in SC connectors only. 

The 100Base-TX interface uses an RJ45 shielded connector.

LEDs 

Installation Guide 

The PWR LED in the upper right corner of the front panel lights when the 

media converter is receiving power. Status LEDs are located on the front 

panel next to each port and described in Table 1. 

Table 1 LEDs 

LED Color State Description 

PWR Green ON Power is applied. 

NML Green ON 

Unit is operating in normal mode. 

OFF Unit is in Link Test mode. 

REC Green ON Data is being received on the port. 

LNK Green ON Link established on the port. 

MDI/MDI-X Switch 

The MDI/MDI-X (Media Dependent Interface/Media Dependent Interface with 

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 switch is MDI-X, which means you can connect the RJ45 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 MissingLink feature 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. 

Note 

Using the Link Test mode does not interfere with the media converter’s 

ability to pass network traffic. 

3

Auto-Negotiation 

The 100Base-TX ports participate in IEEE 802.3u Standard auto-negotiation 

with its local link partner. 

4 

Note 

End stations used with the media converter must operate in the same 

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 example, two media converters installed in a back-to-back 

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. 

Figure 5 External AC-DC Power Adapter (North American version)

Package Contents 

Make sure the media converter package contains the following items: 


❑ AT-MC101XL, AT-MC102XL, AT-MC103XL, or AT-MC103LH Fast 

Ethernet Media Converter 

❑ Four Protective Feet (for standalone use only) 

❑ External AC-DC Power Adapter

Installing the Media Converter 

Read the warnings below before beginning any installation. 

Warning 

Do not stare into the laser beam when installing the media converters. 

�� 5 

LIGHTNING DANGER: DO NOT WORK on equipment or CABLES 

during periods of LIGHTNING ACTIVITY�� 6 

DO NOT BLOCK AIR VENTS �� 7 

The following steps are for a standalone installation. To install media 

converters in a rack mount chassis, see “Rack mount Chassis Installation” on 

page 7. For information concerning back-to-back converter configuration, see 

“Back-to-Back Installation” on page 7. 

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. 

12 VDC

4. Verify that the PWR LED lights green. 

5. Set the unit in Link Test mode 

6. Remove the dust cap from the fiber optic connectors. 

7. Plug the appropriate fiber cable into the connector. See Table 3 for IEEE 

802.3u cabling specifications 

8. Connect the other end of the fiber cable to the desired end station. Verify 

that the link LED is ON. 

9. If you are making a direct connection to a workstation using straightthrough 

cable, set the MDI/MDI-X switch to the MDI-X position. (MDI-X is 

the default position.) 

If you are connecting the media converter to a hub, switch, or another 

media converter with a straight-through cable, set the MDI/MDI-X switch 

to the MDI position. See Figure 7.

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 example, two media converters installed in a back-to-back 

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. 

Back-to-Back Installation 

Review the following before doing a back-to-back installation. See Figure 10 

for an illustration of a back-to-back-media converter configuration. 

❑ During installation, setup, and testing of back-to-back media 

converters, make sure each media converter is in the Link Test mode. 

❑ When two media converters are connected back-to-back with no UTP/ 

STP cables connected and when the NML/LNK TST switch is in the 

OUT position (Link Test mode), the fiber REC LEDs on each converter 

may flash. This is normal and will not affect the normal operation of 

the converters. 

❑ When operating two media converters in a back-to-back configuration, 

Allied Telesyn recommends that the MissingLink feature on one or 

both of the converters be disabled. The MissingLink feature can be 

disabled by placing the NML/LNK TST switch in the OUT position 

(LNK TST mode). Disabling the Link Test mode does not interfere 

with the converter’s ability to pass network traffic. 

Rack mount Chassis Installation 

To install the media converter in the rack-mount chassis, refer to the 

“AT-MCR12 Media Converter Chassis Installation Manual” or visit the 

Technical Support area of Allied Telesyn’s website at 

www.alliedtelesyn.com. Figure 8 shows the AT-MCR12 rack-mount

2. End stations used with the media converter must operate in the same 


3. Verify that the twisted pair cable is Category 5. 

4. Verify that proper fiber cable is being used: multimode for the 

AT-MC101XL and AT-MC102XL, and single mode for the AT-MC103XL 

and AT-MC103LH. Refer to Table 3 on page 10 for cable specifications 

5. Verify that the near end node transmitter (TX) is connected to the far end 

node receiver (RX) and vice versa on the fiber segment.
