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.
