10/100BASE-T Ethernet Switch High-Speed WAN Interface Cards Revised: 6/7/07, OL-12850-01 Overview This document describes Cisco 10/100BASE-T Ethernet switch high-speed WAN interface cards (HWICs) and how to connect Cisco 10/100BASE-T Ethernet HWICs to the network, and contains the following sections: • Cisco 10/100BASE-T Ethernet Switch HWICs, page 1 • Installing a Daughter Card on the HWIC-4ESW Card, page 4 • Scenarios for Cisco 10/100BASE-T Ethernet Switch HWICs, page 6 • Connecting Cisco 10/100BASE-T Ethernet Switch HWICs to Your Network, page 6 • Stacking of Cisco 10/100BASE-T Ethernet Switch HWICs, page -7 • Related Documentation, page 7 • Obtaining Documentation, Obtaining Support, and Security Guidelines, page 8 For an overview of Cisco interface cards used for Cisco access routers see the Cisco Interface Cards for Cisco Access Routers document. Cisco 10/100BASE-T Ethernet Switch HWICs The Cisco 10/100BASE-T Ethernet switch HWIC is available as a 4-port single-wide HWIC (HWIC-4ESW), and as an (8+1)-port double-wide HWIC (HWIC-D-9ESW), providing Layer 2 switching for Cisco modular access routers. Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the 4-port single-wide HWIC (HWIC-4ESW), 4-port single-wide HWIC with PoE (HWIC-4ESW-POE), (8+1)-port double-wide HWIC (HWIC-D-9ESW), and (8+1)-port double-wide HWIC with PoE (HWIC-D-9ESW-POE) only to intra-building or non-exposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends. OL-12850-01 1
