Chapter 1 Overview The AT-MC13 and AT-MC14 media converters are designed to extend the distance of your network over large distances by interconnecting twisted pair cabling to single-mode or multimode fiber optic cabling. These media converters feature a 10Base-T twisted pair port and a 10Base-F fiber optic port. The twisted pair port has an RJ-45 connector and a maximum operating distance of 100 meters (328 feet).
Table 1 lists the maximum operating distances for the AT-MC13 and AT-MC14 media converters. Table 1 Maximum Operating Distances 10Base-F Model 10Base-T Connector Maximum Operating Distance1 Connector Maximum Operating Distance AT-MC13 ST 2 km (1.2 mi) RJ-45 100 m (328 ft) AT-MC14 SC 2 km (1.2 mi) RJ-45 100 m (328 ft) 1. Maximum operating distance may be less depending on the duplex mode of the end-nodes and the type of fiber optic cabling used with the port.
AT-MC13 and AT-MC14 Installation Guide Fiber Optic Port The 10Base-F port on the AT-MC13 and AT-MC14 media converters have either an SC or ST connector designed to operate with multimode fiber optic cabling. This port has a maximum operating distance of 2 kilometers (1.2 miles) using 62.5/125 micron multimode fiber optic cable. Status LEDs Table 2 lists the status LEDs for the AT-MC13 and AT-MC14 media converters.
NML/LNK TST Button The NML/LNK TST (Normal MissingLink/Link Test) button allows you to perform a link test on the ports on the media converter. This button also allows you to activate the MissingLink feature on the unit. The MissingLink and Link Test features are describe below. MissingLink. The MissingLink feature activates the ports on the media converter to pass the “Link” status of their connections to each other.
AT-MC13 and AT-MC14 Installation Guide Auto-negotiation Auto-negotiation determines the duplex mode of the ports. The duplex mode refers to the manner in which an end-node sends and receives data on the network. Depending on its capabilities, an end-node can operate in either halfor full-duplex mode. An end-node operating in half-duplex can either send or receive data, but not both at the same time. However, an end-node operating in full-duplex can send and receive data simultaneously.
External AC/DC Power Adapter An external AC/DC power adapter is included with the media converter for desktop operation. The power adapter supplies 12 V 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 requirement for these media converters is 12 V DC, 500 mA. Note The power adapter is not used if you install the media converter in an AT-MCR12 chassis.
AT-MC13 and AT-MC14 Installation Guide Back-to-Back Topology In some network configurations you may want to interconnect two media converters in what is referred to as a back-to-back topology. In this topology, the media converters not only extend the distance of your network but also convert the fiber optic cable from twisted pair to fiber optic and back again. Figure 5 illustrates two AT-8224XL switches at different campuses interconnected by two AT-MC14 media converters.
Chapter 2 Installing the Media Converter This chapter explains how to install an AT-MC13 and AT-MC14 media converter on a desktop. To install the media converter in an AT-MCR12 chassis, refer to the AT-MCR12 Installation Guide. This guide can be downloaded from our web site at www.alliedtelesyn.com. Verifying Package Contents Make sure the following items are included in your media converter package. If any item is missing or damaged, contact your sales representative for assistance.

Installing the Media Converter To install an AT-MC13 and AT-MC14 media converter, perform the following procedure: 1. Remove all equipment from the package and store the packaging material in a safe place. Note Do not remove the dust cover from the fiber optic port until you are ready to connect the fiber optic cable. Dust contamination can adversely impact the operating performance of the port and the media converter. 2.
AT-MC13 and AT-MC14 Installation Guide 8. Plug the AC/DC power adapter into an appropriate AC power outlet and insert the power plug into the DC receptacle located on the back of the unit. This step does not apply if you installed the unit in an AT-MCR12 chassis. 9. Verify that the Power LED is green. If the LED is OFF, refer to “Troubleshooting” on page 15 for instructions. 10. Power ON the end-nodes. 11. Verify that the LNK LEDs for the fiber optic port and the twisted pair port are green.
Chapter 3 Troubleshooting Follow the guidelines below to test and troubleshoot the installation in the event a problem occurs. If the PWR LED is OFF, do the following: q If the unit is installed on a desktop, check to be sure that the power adapter is securely connected to a power outlet and that the power adapter cable is securely connected to the back of the media converter. q If the unit is installed in an AT-MCR12 chassis, check that the unit is fully seated in the slot.
If the LNK LED for the fiber optic port is OFF, do the following: q Verify that the end-node connected to the port is ON and is operating properly. q Check that the fiber optic cable is securely connected to the fiber optic port on the media converter and on the end-node. q Check to be sure that the end-node connected to the port is operating at 10 Mbps. q Make sure that the fiber optic port on the end-node is operating in either half- or full-duplex mode.
AT-MC13 and AT-MC14 Installation Guide If the LNK LED for the fiber optic port is ON, but there is a communication problem between the end-nodes connected to the media converter (and you are not running a link test), check the following: q Check that the end-nodes connected to the ports are operating at 10 Mbps. q Check that the end-nodes are operating in the same duplex mode. These units can operate in either half- or full-duplex mode.
