Introduction Thank you for choosing the Metrobility “twister” media converter. Metrobility “twister” 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 “twister” 2131 multimode-to-singlemode (MM-to-SM) media converters provide seamless high-speed integration of multimode and singlemode fiber optic segments in Fast Ethernet environments. The “twister” 2131 supports remote fiber optic links up to 2km over multimode and up to 15km 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 “twister” media converter. 1 Unpack the “twister” and Accessories Check that the following components have been included with your order: • “twister” 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 LLCF Switch Link Loss Carry Forward (LLCF) Switch. The MM-to-SM 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 on the “twister” media converter do not transmit a link signal until they receive a link signal from the opposite port.
4 Connect to the Network The Metrobility “twister” 2131 MM-to-SM media converter offers the ease of plug-and-play installation. The 2131 MM-to-SM media converters provide one duplex multimode SC/ ST port and one duplex singlemode SC/ST port for 100BASE-FX connections. The multimode connectors support links up to 2km and the singlemode connectors support links up to 15km.
5 Apply Power Power is provided to the “twister” unit from the desktop power supply module. This power module is equipped with a S760 hollow-type plug for insertion into the DC jack located on the back of the “twister” unit and standard IEC 320-type AC power receptacle. When making power connections, it is recommended that the DC power cord be connected to the DC input jack located on the back of the “twister” media converter before making the AC connection to the outlet.
While one end of the AC power cord can be fitted with whatever plug is standard for the country of operation, the end that connects to the “twister” 2131 power supply module must have a female plug that fits this type of AC receptacle. • AC 115V (North American): use a UL-listed and CSA-certified cord set consisting of a minimum 18 AWG, type SVT or SJT three-conductor cord, a maximum of 15 feet in length and a parallel blade, grounding-type attachment plug rated 15A, 125V.
User Guide This section contains more detailed information regarding the operating features for the Metrobility 2131 “twister” media converter. System LEDs The Metrobility “twister” MM-to-SM 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 “twister” 2131 has been designed with LLCF functionality for troubleshooting a remote connection. The unit is shipped with the LLCF disabled. When LLCF is enabled, the FX ports on the “twister” do not transmit a link signal until they receive a link signal from the opposite port. For example, if LLCF is enabled and two “twister” units are connected via a fiber cable with nothing else connected to them, the Link LED does not illuminate.
