2 O VERVIEW OF THE S WITCH 4005This chapter provides an introduction to the design of the 3Com® Switch 4005.The topics in this chapter include: Product Overview Switch Backplane ArchitectureProduct Overview The Switch 4005 is a feature-rich, 14-slot, modular routing switch that can beconfigured with up to 24 Gigabit Ethernet ports or up to 96 Fast Ethernet portswith currently available modules. The Switch 4005 currently supports redundantpower supplies, redundant Switch Fabric Management Modules, and a variety ofFast Ethernet and Gigabit Ethernet Interface Modules. Combining the speed andlow cost of a Layer 2 switch with Layer 3 routing capabilities, the Switch 4005currently routes the IP protocol and offers many other advanced features toprovide the high performance that you need to aggregate wiring closets in yournetwork.Physical Description A Switch 4005 chassis can contain: Two fan trays.Each fan tray contains two fans (four fans total). Both fan trays are required fornormal operation. Two 300 Watt AC power suppliesOnly one power supply is required for normal operation. If installed, a secondpower supply provides load-sharing and redundancy. Two Switch Fabric Management Modules (SFMMs)Only one SFMM is required for normal operation. If the SFMM is removed froma powered up chassis that is functioning in a network, chassis operations willcease. However, if a backup SFMM is installed in the chassis, and the primarySFMM is removed or fails, the backup SFMM will take over operations.The SFMM has two elements: a central switch fabric, which manages thelayer 3 routing functions of the system such as routing table updates andlayer 3 configuration changes, and the management of the system, whichincludes SNMP, command line interface (CLI), and Web client activities. Up to Twelve Fast Ethernet or Gigabit Ethernet Interface ModulesYou install the number and type of interface modules that are appropriate toyour cabling infrastructure and bandwidth requirements. When the source anddestination ports are located on the same interface module, the interfacemodule performs local switching. If the destination port resides on a differentinterface module, the interface module forwards the packet to the SFMM.
