The FEIP2-DSW is a dual-port, fixed configuration interface processor that provides two, 100-Mbps, IEEE 802.3u Fast Ethernet (FE) interfaces and the capability for Distributed Services (DS) and Distributed Switching (DSW). Each 100BASE-FX interface on the FEIP2-DSW-2FX has an SC-type fiber-optic connector for 100BASE-FX, and an MII connector that permits connection through external transceivers to 62.5/125-micron multimode optical fiber for 100BASE-FX, or to Category 3, 4, and 5 UTP or shielded twisted-pair (STP) for 100BASE-T4 physical media.
