Connecting to the Network6E122-26, 6E132-25, 6E123-26 and 6E133-25 User’s Guide 3-53.5 CONNECTING TO THE NETWORKThis section provides the procedures for connecting segments from thenetwork or other devices to the modules.Ports 1 through 24 on the 6E122-26 and 6E132-25 have RJ45 connectorsfor twisted pair connections. Ports 1 through 24 on the 6E123-26 and6E133-25 have RJ21 connectors for twisted pair connections. Ports 25and 26 of the 6E12X-26 support FE-100TX, FE-100FX, or FE-100F3Fast Ethernet Interface Modules. The FE-100TX has an RJ45 connectorfor a Category 5 UTP cable connection. The FE-100FX has an SC styleconnector for a multimode fiber optic cable connection. The FE-100F3has an SC style connector for a single mode fiber optic cable connection.Refer to Section 3.5.1 to make twisted pair connections to ports 1 through24 of the 6E122-26 and 6E132-25.Refer to Section 3.5.2 to make twisted pair connections to ports 1 through24 of the 6E123-26 and 6E133-25.Refer to Section 3.5.3 to make a Twisted Pair connection to anFE-100TX.Refer to Section 3.5.4 to make a fiber optic connection to an FE-100FX orFE-100F3.NOTEIf the 6E12X-26 and 6E13X-25 are being installed in a networkusing SmartTrunking, there are rules concerning the networkcable and port configurations that must be followed forSmartTrunking to operate properly. Before connecting thecables refer to the Cabletron SystemsSmartTrunk User’sGuide shipped with the modules..
