Creating an XRN Distributed Fabric 25 How To Interconnect Units You can interconnect your Switches to create an XRN Distributed Fabric using one of the following methods: ■ XRN Interconnect Kit (3C17715) - consists of two XRN Interconnect Modules and a 1 meter (3.28 feet) Interconnect cable. Should you wish to connect two Switch units together that are located in separate racks you can obtain a 5 meter (16.4 feet) Interconnect cable (3C17722). Contact your network supplier for further information. ■ SuperStack 3 Switch 4900 Family GBIC Module (3C17714) operating in XRN mode. Using the GBIC Module in this way means you can have an Fabric Interconnect extended up to 70 Km (43.5 miles) between the units, if necessary (dependant upon GBIC transceiver type). For a detailed description of how to create an XRN Distributed Fabric using either of these methods, please refer to the user documentation that accompanies the Kit or the GBIC Module. The documentation can also be located on the 3Com Web site.

Ensure that the Switch is powered off before inserting or removing a Module.
