Cisco HWIC-D-9ESW 9-Port EtherSwitch High-Speed WAN Interface Card

The Cisco HWIC-D-9ESW is a 9-Port EtherSwitch High-Speed WAN Interface Card that adds integrated Ethernet switching to Cisco Integrated Services Routers. It provides 9 × 10/100 Fast Ethernet switching ports and functions as an integrated Layer 2 Ethernet switch, enabling local network connectivity for devices such as workstations, printers, and IP phones through a single router module. Managed through Cisco IOS software and installed as a plug-in in HWIC slots on compatible Cisco ISR platforms, it supports standard Ethernet networking (IEEE 802.3, IEEE 802.3u) to extend branch and remote-office networks. Common replacements for this interface card include Cisco EHWIC-D-8ESG, HWIC-D-9ESW-POE, and NIM-ES2-8 EtherSwitch Network Interface Module.
