AT-MC105XL and AT-MC106XL Fast Ethernet Media Converters The AT-MC105XL and AT-MC106XL convert IEEE 802.3u 100Base-TX to 100Base-SX multimode Fast Ethernet network connections. The 100Base-SX interface is available in ST or SC connectors for multimode fiber cabling. The 100Base-TX interface uses an RJ45 shielded connector.
Key Features The media converters have the following key features: ❑ LEDs for unit and port status ❑ MDI/MDI-X Switch ❑ NML/LNK TST Switch ❑ 100Base-TX ports participate in auto-negotiation for 100 Mbps and half- or full-duplex modes ❑ MissingLink provides link fault detection on 100Base-TX segments ❑ External AC-DC Power Adapter ❑ Standard, compact size for use with AT-MCR12 rack-mount chassis ❑ Low power consumption Note For definitions of technical terms associated with Allied Telesyn p
AT-MC105XL and AT-MC106XL Installation Guide 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.
External AC-DC Power Adapter An external AC-to-DC power adapter is included with the fast switch for standalone operation (see Figure 3).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 outp of 12 V DC at 1 A. The power required for the media converter is 12 V DC, 500 mA.
AT-MC105XL and AT-MC106XL Installation Guide Installing the Media Converter Read the warnings below before beginning any installation. Warning LIGHTNING DANGER: DO NOT WORK on equipment or CABLES during periods of LIGHTNING ACTIVITY! 1 DO NOT BLOCK AIR VENTS ! 2 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.
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 Figure5.
AT-MC105XL and AT-MC106XL Installation Guide Back-to-Back Installation Review the following before doing a back-to-back installation. See Figure8 f or 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.

AT-MC105XL and AT-MC106XL Installation Guide Troubleshooting To troubleshoot your media converter,perform the following: 1. Set the unit in the Link test Mode. 2. End stations used with the media converter must operate in the same duplex mode (either both full-duplex or both half-duplex). 3. Verify that the twisted pair cable is Category 5. 4. Verify that proper fiber cable is being used: multimode for the AT-MC105XL and AT-MC106XL. 5.
Recommended Cables and Cable Specifications Table 3 lists the IEEE 802.3u cabling specifications for the media converters. Refer to this table for cabling recommendations.
