The module has twelve10/100BASE-TX Fast Ethernet front panel ports thatprovide a 100 Mbps connection over UTP-Category 5cables, and one nonblocking Gigabit Ethernet portthat connects through the backplane to the switchfabric module. The module has two groups of sixports, operates as a Layer 3 router switch, andoccupies a single interface module slot in theSwitch 4007 chassis.Figure 11 identifies the components on the frontpanel of the module.Figure 11 Front Panel of Module 3CB9RF12RTo learn more about this module, refer to the 12-Port10/100BASE-TX Fast Ethernet Layer 3 SwitchingModule Quick Start Guide on the Online ManualsCD-ROM.Gigabit Ethernet ModulesThe Gigabit Ethernet (GEN) Interface Modules aretwo-port interface modules for the 3ComSwitch 4007. The GEN interface modules serve as a2–Gigabit data channel between the Gigabit EthernetSwitch Fabric Module and other 802.3z–compliantGigabit Ethernet devices. GEN Interface Modules useSC connectors.Because Gigabit Ethernet interface modules are notintelligent, you cannot access them directly; allcommunication takes place through the switch fabricmodule. GEN interface modules serve as atwo-Gigabit data channel between the GEN SwitchFabric Module and other 802.3z-compliant Ethernetdevices.For information about how to install these modules,see the module’s Quick Start Guide that is shippedwith each module.Gigabit Ethernet Interface Modules are available inthese port configurations:n 4-port Gigabit Ethernet Interface Modulen 9-port 1000BASE-SX Gigabit Ethernet Layer 2Switching Modulen 4-port Gigabit MultiLayer Switching Module3CB9LF36R161XMOD STAT31367X13X19X25X31X3CB9RF12R1MOD STAT23478910511612123456789101112
