Introduction Thank you for choosing the Metrobility 2131 media converter. Metrobility 2131 media converters represent the hottest technology available for extending Ethernet and Fast Ethernet networks. Since Metrobility first developed “twister” media conversion, it has become a standard for providing a cost-effective means of integrating a mixed media environment. As LANs grow and evolve, this technology provides an ideal solution for building effective migration strategies. These IEEE 802.
Overview The Metrobility 2131 100Mbps TX-to-FX media converter provides seamless high-speed integration of 100BASE-TX twisted-pair and 100BASE-FX fiber optic segments in Fast Ethernet environments. The 2131 supports remote fiber optic links up to 2km over multimode and up to 100km over singlemode fiber optic cable. To optimize your Fast Ethernet network, this innovative media converter provides seamless operation in half-duplex or full-duplex environments.
Installation Guide Follow the simple steps outlined in this section of the guide to install and start using your Metrobility 2131 media converter. 1 Unpack the “twister” Media Converter and Accessories Check that the following components have been included with your order: • 2131 media converter • Power supply • Power cord • Four (4) rubber feet Your order has been provided with the safest possible packaging, but shipping damage does occasionally occur. Inspect your order carefully.
3 Set the Switches Link Loss Carry Forward (LLCF) Switch The 2131 media converter incorporates Link Loss Carry Forward (LLCF) functionality as an aid in troubleshooting a remote connection. A switch for enabling/disabling LLCF is located on the rear panel of the converter. When LLCF is enabled, the FX ports as well as the TX ports on the media converter do not transmit a link signal until they receive a link signal from the opposite port.
“twister” ™ 2131 100BASE-FX 100BASE-TX PWR TX SM AT RX LK AT LK MDI-II / MDI-X Switch (default is MDI-II) When setting the MDI-II to MDI-X switch, observe the positioning of the following symbols: • the parallel symbol (II ) indicates a straight through or parallel connection. (default) • the cross symbol (X) indicates a crossover connection. These symbols are clearly marked on the bottom of the unit. Using a pointed object, simply slide the switch in the direction of the appropriate symbol.
4 Connect to the Network The Metrobility 2131 media converter offers the ease of plug-and-play installation. Each 2131 media converter provides one shielded RJ-45 connector and supports a maximum segment length of 100 meters for Category 5 twistedpair. The 2131 also comes with the following connectors: • The 2131-13-01 and 2131-15-01 provide one set of FX multimode SC/ ST connectors, respectively, and supports a maximum segment length of up to 2km for remote links.
• The 2131-1X-01 and 2131-1Y-01 provide one singlemode bidirectional wavelength division multiplexed (BWDM) SC connector which supports a maximum segment length of up to 20km for remote links. BWDM units must always be used in complementary pairs. That is, a-1X model must be connected to a -1Y. The -1X unit is designed to transmit data at a wavelength of 1550nm and receive at 1310nm. Correspondingly, the -1Y unit transmits data at 1310nm and receives at 1550nm.

User Guide This section contains more detailed information regarding the operating features for the 2131 media converter. System LEDs The Metrobility 2131 media converter provides LEDs for the visible verification of unit status and proper functionality as well as aiding in troubleshooting and overall network diagnosis and management. LEDs indicate the following: • PWR (power): the unit is ON and functioning in normal operation mode.
Link Loss Carry Forward (LLCF) The Metrobility 2131 has been designed with a LLCF function for troubleshooting a remote connection. The unit is shipped with the LLCF disabled. When LLCF is enabled, the fiber optic ports as well as the twisted-pair ports on the 2131 media converter do not transmit a link signal until they receive a link signal from the opposite port.
