The second-generation Fast Ethernet Interface Processor (FEIP2-DSW) with distributed switching and distributed services (see the following figure) provides two Fast Ethernet (100 Mbps) ports, which support twisted-pair or fiber-optic cable. It provides significantly higher throughput characteristics in full-duplex operation than the previous generation FEIP. The 100BaseT interfaces are mounted on port adapters that attach to the FEIP2-DSW motherboard. Each port adapter has two 100BaseT interfaces: one RJ-45 and one MII connection. Only one connection can be used per port adapter.
Each 100BaseT port on the FEIP2-DSW has an RJ-45 connector to attach to Category 5 UTP for 100BaseTX, and an MII connector that permits, through user-provided transceivers, connection to other physical layers. Only one connector on an FE port adapter can be used at one time. Both full-duplex and half-duplex operations are supported on each interface.
The FEIP2-DSW can operate with a variety of 100BaseFX or 100BaseTX devices, for example, a Catalyst 5000 switch with Fast Ethernet interface modules installed. The Cisco 7000 series and Cisco 7500 series router must be running Cisco IOS Release 11.1(10)CA or later. The FEIP2-DSW provides 2 MB of SRAM and 32 MB of DRAM.
