Introduction Thank you for choosing the “twister”™ Media Converter 7000. The “twister” Media Converter provides a cost-effective means of integrating a mixed media environment. The information in this guide helps you to install and start using your “twister” Media Converter 7000.
The TELCO connection provides a convenient means of connecting to an MDF-ready hub, switch or patch panel. The “twister” Media Converter 7000 offers three models with TELCO connectors. The LE7312A-PS-R2 is a 12-slot 2U chassis with dual 50-pin TELCO connectors. This chassis is available with dual load-sharing power supplies to ensure essential non-stop networking for high priority traffic and business-critical applications.
Related Documentation Refer to the following documentation for additional specific information on the “twister” Media Converter 7000: • Media Converter 7000 “redundant twister”™ Modules Installation & User Guide • “twister”™ Media Converter 7000 Modules Quick Reference “twister” Media Converter 7000 7
Installation Guide Follow the simple steps outlined in this section of the manual to install and start using the “twister” Media Converter 7000 chassis. 1 Unpack the chassis and any accessories.
Because of its smaller size, the LE7306A chassis can be placed on any flat surface. To save space and keep the installation area organized, use the optional wall mount bracket. Follow these simple instructions and refer to the diagram below: • Place the bracket up against the wall and use a pencil to mark where the anchors will be placed.
3 Set the Switches and Jumpers. Locate the switches and jumpers. The following illustrations show the orientation of the DIP switches and LLCF jumpers for the 10Mbps and 100Mbps “twister” modules.* These illustrations are generalized and not specific to a particular module. Refer to the “redundant twister” module diagrams in the User Guide section of this document for more detailed information on the location and setting of the DIP switches for these particular modules.
MDI-II to MDI-X All “twister” modules with twisted-pair ports* have an MDI-II to MDI-X switch. This switch is positioned directly behind it’s associated RJ-45 connector and allows simple setup in either straight through (default) or crossover configurations. 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.
4 Install the “twister” 7000 Modules. Each chassis supports multiple 10 and 100Mbps media types— via “twister” modules—in any combination. The modules offer the ease of plug-and-play installation and are hot-swappable. While these 7000 Series chassis support media conversion for any Media Converter Module, only certain modules will work in conjunction with the TELCO connector on the back of these chassis.
Follow these simple steps to install “twister” modules: • Grasp a module by the front panel as shown. • Insert the module into a slot making sure that both the top and bottom of the card edges are lined up with the top and bottom slot guides. Do not force the module into the chassis unnecessarily. It should slide in easily and evenly. • Slide the module in until the top and bottom edges of the front panel are flush and even with the top and bottom edges of the chassis.
5 Connect to the Network. To connect the individual “twister” modules to the network, refer to the appropriate section in the the User Guide section of this manual. • For more detailed information regarding the “redundant twister” module, refer to the Media Converter 7000 “redundant twister” Modules Installation & User Guide. 6 Apply power to the chassis. The “twister” Media Converter 7000 Power Supply Module provides up to 60W of power to the chassis.
Each power supply includes a standard North American 3-pin power cord which is UL (USA), CSA or CUL (Canada) listed or approved. For installation in regions outside North America, replace the power cord with a cord approved by appropriate safety agencies. Any cord must have a CEE-22 standard V female connector on one end and meet IEC 320-030 specifications.

Operating Features of the “twister” Power Supply Modules Load Sharing Power Supply Modules (LE7312A-R2, LE7312-PS-R2) When a chassis is equipped with two load-sharing power supply modules, they operate in tandem and share the connected load. This decreases the demand put on each individual unit. There are two LEDs on the front panel of each Power Supply Module.
Power Supply Service Instructions The following instructions explain the procedure to follow when replacing a Power Supply Module or installing a second Power Supply Module in the “twister” LE7306A, LE7312A-R2 or LE7312-PS-R2 chassis. IMPORTANT The Power Supply Module is an open frame-type power supply — LIVE VOLTAGES ARE PRESENT — and poses a danger if the module is installed improperly.
• Insert the module into the slot making sure that the edges are in the guides. Do not force the Power Supply Module into the chassis unnecessarily. The module should slide in easily. • Slide the Power Supply Module into the chassis until the front panel is flush and even with the chassis. • Turn the thumb screw to the right and tighten to secure the power module into the chassis.
Link Loss Carry Forward (LLCF) The “twister” modules (with the exception of the 10Mbps BNC and TELCO modules) have been designed with an LLCF function for troubleshooting a remote connection. The modules are shipped with the LLCF disabled. When LLCF is enabled, the FX ports as well as the TX ports on the “twister” modules, do not transmit a link signal until they receive a link signal from the opposite port.
