Cisco WIC-4ESW

The Cisco WIC-4ESW is a Wide Area Network Interface Card (WIC) module designed for Cisco routers. It provides four 10/100 Ethernet switch ports, allowing the router to connect to local Ethernet devices. The WIC-4ESW is commonly used in small office or branch office environments where there is a need for additional Ethernet ports. It is hot-swappable and can be easily installed or removed from the router without powering down the system.
