Chapter 1: Overview Features The AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules are designed to interconnect Fast Ethernet networking devices over large distances by transferring Fast Ethernet network packets between twisted pair cable and fiber optic cable. The modules feature twelve independent media converter channels with each channel consisting of one 10/100Base-TX twisted pair port and one 100Base-FX fiber optic port.
AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules Installation Guide 2 km (1.24 mi.) maximum operating distance using 50/125 µm or 62.5/125 µm (core/cladding) multimode fiber optic cable for the fiber optic ports on the AT-MCF2012LC module 20 km (12.4 mi.
Chapter 1: Overview Front Panels The front panels of the two media converter modules are identical. They are identified with the model name on the left side of the faceplate. AT-MCF2012LC Figure 2 shows the front panel of the AT-MCF2012LC Media Converter Module.
AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules Installation Guide Media Converter Channels The AT-MCF2012LC and AT-MCF2012LC/1 modules have twelve independent media converter channels. Each channel forwards Fast Ethernet network traffic between one 10/100Base-TX twisted pair port and one 100Base-FX fiber optic port. The channels are predefined.
Chapter 1: Overview Twisted Pair Ports The twisted pair ports feature standard RJ-45 8-pin connectors and operate at either 10 or 100 Mbps in either half- or full-duplex mode. The ports use TIA/EIA 568-Bcompliant Category 3 or better cable for 10 Mbps operation and Standard TIA/EIA 568-A-compliant Category 5 or TIA/ EIA 568-B-compliant Enhanced Category 5 (Cat 5e) cable for 100 Mbps operation. The ports have a maximum operating distance of 100 meters.
AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules Installation Guide The auto-MDI/MDI-X feature is only available when a twisted pair port is using Auto-Negotiation, the default setting. If you disable Auto-Negotiation and set the port speed and duplex mode manually, this feature is disabled as well and the port defaults to the MDI-X setting.
Chapter 1: Overview Fiber Optic Ports The fiber optic ports have duplex LC connectors. They are 100Base-FX compliant with a fixed operating speed of 100 Mbps. The duplex mode of these ports can be either half- or full-duplex mode. The default setting is full duplex. Adjusting the duplex mode of a fiber optic port requires the optional management module for the chassis. The fiber optic ports on the AT-MCF2012LC module have a maximum operating distance of 2 km and use 50/125 or 62.
AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules Installation Guide Port and Channel LEDs The LEDs on the media converter module reflect packet activity, link status, duplex mode and collisions of the ports, as well as the operating mode of the channels. “A” Activity LED Each port on the module has an Activity (A) LED, shown in Figure 5. The Activity LED blinks to indicate when a port is transmitting or receiving network packets from the networking device connected to it.
Chapter 1: Overview “L” Link LED The twisted pair ports and fiber optic ports also have a Link (L) LED, shown in Figure 6, for displaying the link status of a port to its networking device. The meaning of a Link LED can vary depending on the operating mode of a channel. Consequently, you should first determine a channel’s operating mode before deciphering the Link LEDs of a channel’s two ports.

Both ports in the channel have established a link with a networking device. The twisted pair port is operating at 100 Mbps (green) or 10 Mbps (amber) link and the fiber optic port at 100 Mbps.
AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules Installation Guide Table 5.
Chapter 1: Overview CDC and FDC Duplex Mode and Collision LEDs The CDC and FDC LEDs shown in Figure 7 display the duplex mode of the ports in a channel and, for ports operating in half-duplex mode, the collisions. The CDC (Copper, Duplex mode, Collisions) LED displays this information for the twisted pair port of a channel, while the FDC (Fiber optic, Duplex mode, Collisions) LED displays the same information for the fiber optic port.
AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules Installation Guide The CDC and FDC LEDs are described in Table 6. Table 6. CDC and FDC Duplex Mode and Collisions LEDs LED CDC FDC State Description Off The twisted pair port in the channel has not established a link with its networking device. Steady Green The twisted pair port is operating in full-duplex mode. Steady Amber The twisted pair port is operating in half-duplex mode.
Chapter 1: Overview LT, ML, and SML Channel Operating Mode LEDs The LT, ML, and SML LEDs shown in Figure 7 display the operating mode of a media converter channel. The operating mode can be Link Test (LT), MissingLink (ML), or Smart MissingLink (SML). The LEDs can display the mode of only one channel at a time. To select a channel, refer to “Mode Selection Button” on page 36. For a description of the channel operating modes, refer to “Channel Operating Modes” on page 31.
AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules Installation Guide Channel Operating Modes A media converter channel has three operating modes. The operating modes are: Link Test mode MissingLink mode Smart MissingLink mode The operating mode of a channel is set with the Mode Selection button on the front panel of the module, as explained in “Mode Selection Button” on page 36 or with the optional management module for the chassis.
Chapter 1: Overview transmitter on the companion port. This notifies the networking device connected to the port of the loss of the link on the other channel port. Without the MissingLink mode, a networking device connected to a port on the media converter will not be aware of a loss of a link on a companion port in the channel, because its link to the media converter would be unaffected.
AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules Installation Guide node connected to that port of the loss of the link on the fiber optic port. The Link LEDs of the ports in a channel running in this mode always operate in tandem, as shown in Table 4 on page 26. They can be both on or off. Both Link LEDs of the ports of a channel operating in this mode remain off until both ports can establish a link with their networking device.
Chapter 1: Overview Here is an example of how the Smart MissingLink mode works. Assume that the fiber optic port in a media converter channel lost its link to its networking device while the channel was in the Smart MissingLink operating mode. The mode would respond by pulsing the transmitter on the twisted pair port of the channel about once a second, and flashing the port’s Link LED.
AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules Installation Guide Guidelines to Using the Channel Operating Modes Here are the guidelines to using the channel operating modes: Different channels on the module can operate in different modes. The operating modes do not block or interfere with the flow of traffic between the two ports of a channel, and so can be used during normal network operations.
Chapter 1: Overview Mode Selection Button The Mode Selection button shown in Figure 8 serves two purposes. One is to set the operating mode of a channel. The three operating modes are described in “Channel Operating Modes” on page 31.
AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules Installation Guide SML LEDs, explained in “LT, ML, and SML Channel Operating Mode LEDs” on page 30. A change of the operating mode is immediately activated on a channel. Here is an example on how to use the Mode Selection button. Assume you wanted to determine the duplex mode of the two port in channel 6 (i.e., twisted pair port 6 and fiber optic port 6) and change the operating mode of the channel to the Link Test mode.
Chapter 1: Overview Guidelines to Using the Media Converter Module This section lists the factors to be considered as part of the planning process prior to the installation of an AT-MCF2012LC or AT-MCF2012LC/1 media converter module. In order for local and remote networking devices to forward traffic to each other through the media converter module, they must be connected to ports of the same channel.
AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules Installation Guide During normal network operations, a media converter channel can operate in any of the three operating modes. For an explanation of the modes, refer to “Channel Operating Modes” on page 31. The default setting for a twisted pair port on the media converter module is Auto-Negotiation and auto-MDI/ MDI-X. The default duplex mode setting for a fiber optic port is full-duplex.

Chapter 2: Installation Cabling the Media Converter Module You may find it useful to first review the information in “Media Converter Channels” on page 19 and “Guidelines to Using the Media Converter Module” on page 38 prior to connecting the network cables to the module. Observe the following guidelines when connecting a cable to a twisted pair port: An RJ-45 connector should fit snugly into the port on the module and the tab on the connector should lock the connector into place.
AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules Installation Guide Verifying the Installation This procedure verifies the installation of the media converter module by determining whether the ports in the channels can establish a link to their networking devices. This procedure assumes the following: The media converter chassis is powered on. The network cables are connected to the ports on the media converter module and to the local and remote networking devices.
Chapter 2: Installation page 31. 4. 54 If a Link LED for a port in the channel is off, the port is unable to establish a link to its networking device. For suggestions on how to resolve the problem, go to Chapter 3, “Troubleshooting” on page 55. Repeat this procedure to test the ports in the other channels.
Chapter 3 Troubleshooting This chapter contains suggestions on how to troubleshoot the AT-MCF2012LC and AT-MCF2012LC/1 media converter modules should a problem occur. For suggestions on how to troubleshoot a problem with the chassis, refer to the Installation Guide that ships with the chassis. Problem 1: Cables are connected to the ports on the media converter module and the chassis is powered on, but all of the port LEDs on the module are off. Solution: Examine the LT, ML, and SML LEDs on the module.
Chapter 3: Troubleshooting After setting the channel to the Smart MissingLink or Link Test mode, observe the Link LEDs for the ports of the channel again. If the Link LED for the twisted pair port is off, go to Problem 3. If the Link LED for the fiber optic port is off, go to Problem 4. Problem 3: The Link LED for the fiber optic port in a channel is on or blinking, but the Link LED for twisted pair port of the same channel is off.
AT-MCF2012LC and AT-MCF2012LC/1 Media Converter Modules Installation Guide specifications, refer to “100Base-FX Fiber Optic Port Specifications” on page 63.
