Chapter 1 Overview The AT-MC13 Ethernet Media Converter is designed to extend the distance of your network by interconnecting twisted pair cabling to singlemode or multimode fiber optic cabling or thinnet cabling. The AT-MC13 media converter allows you to interconnect LAN devices over large distances. The AT-MC13 media converter features a 10Base-T twisted pair port and a 10Base-FL fiber optic port. The twisted pair port has an RJ-45 connector and a maximum operating distance of 100 meters (328 feet).
Chapter 1: Overview Key Features The AT-MC13 media converter has the following key features: LEDs for unit and port status Full- or half-duplex mode operation MissingLink™ notifies end-nodes of link failures (fiber models only) Link Test feature performs a link test on the media converter’s fiber port MDI/MDI-X switch that eliminates the need for a crossover cable NORMAL/LNK TST button that performs a link test on the media converter External AC/DC power adapters (North America,
AT-MC13 Media Converter Installation Guide Twisted Pair Port The AT-MC13 media converter has one 10Base-T twisted pair port. The twisted pair port features a RJ-45 connector. The maximum operating distance for the twisted pair port is 100 meters (328 feet) when operating at 10 Mbps. Fiber Optic Port The AT-MC13 media converter has one 10Base-FL port. The fiber optic port features an ST connector. The maximum operating distance for the fiber optic port for both the AT-MC13 is 2 kilometers (1.
Chapter 1: Overview depending on its capabilities. An end-node that is operating in half-duplex mode can either send data or receive data, but it cannot do both at the same time. An end-node that is operating in full-duplex mode can send and receive data simultaneously. The best network performance is achieved when an end-node can operate at full-duplex, since the endnode is able to send and receive data simultaneously.
AT-MC13 Media Converter Installation Guide MDI/MDI-X Switch An RJ-45 port on a 10 Mbps Ethernet network device can have one of two possible wiring configurations: MDI or MDI-X. The RJ-45 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. To connect two 10 Mbps network devices together that have dissimilar port wiring configurations, such as MDI to MDI-X, you use a straightthrough cable.
Chapter 1: Overview NORMAL/LNK TST Button The AT-MC13 media converter features a NORMAL/LNK TST (Normal MissingLink/Link Test) button, shown in Figure 5. The 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. This button sets the fiber port into an artificial link transmission state for testing without the twisted pair port being connected.
AT-MC13 Media Converter Installation Guide The value to this type of network monitoring and fault notification is that some hubs and switches can be configured to take a specific action in the event of the loss of connection on a port. In some cases, the unit can be configured to seek a redundant path to a disconnected end-node or send out a trap to a network management station, and so alert the network administrator of the problem.
Chapter 1: Overview External Power Adapter An external AC/DC power adapter, shown in Figure 6, is provided with the media converter for use on a desktop. The power adapter supplies 12 VDC to the media converter. Allied Telesis supplies an approved safety compliant AC power adapter for the 120 V AC and 240 V AC versions with an unregulated output of 12 VDC at 1 A. The power required for the media converter is 12 VDC, 500 mA.
AT-MC13 Media Converter Installation Guide Network Topologies The AT-MC13 media converter can be used in two different topologies: Standalone and Back-to-Back. Both types of topologies are described below. Standalone Topology A standalone topology uses one media converter between the endnodes. Figure 7 illustrates a standalone topology that uses an AT-MC13 media converter to connect a workstation and a switch with 10Base-FL uplink port.
Chapter 1: Overview 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 8 illustrates two 10/100Base-TX switches at different campuses interconnected by two AT-MC13 media converters.
Chapter 2 Installation This chapter explains how to install the AT-MC13 media converter. This media converter can be used on a desktop or installed in an AT-MCR1 or AT-MCR12 chassis.
