Cisco Systems EHWIC-4ESG= - 4 Port 10/100/1000 Ethernet Switch Interface Card

When inserted in a Cisco 1900 2900 or 3900 Series ISR the Gigabit Ethernet EHWICs provide a fully integrated secure networking and converged IP communications solution. From a single platform with an integrated switch you can connect IP phones wireless access points and IP-based video cameras to your network and power them using the IEEE 802.3af or Cisco ePoE. With the optional integration of Cisco Unified Communications Manager Express the router can also provide call processing for the phones. As users attempt network access the Gigabit Ethernet EHWIC can use IEEE 802.1x to validate the credentials of the end device and place the users in the appropriate VLAN or Cisco TrustSec™ group. As the end-user data leaves the LAN the router can then encrypt the traffic and place it on a multitude of VPNs securing the communications among branch offices and central sites.The 4- and 8-port Cisco Gigabit Ethernet Enhanced High-Speed WAN interface cards (EHWICs) can reduce your company's total cost of ownership (TCO) by integrating Gigabit Ethernet (GE) switch ports within Cisco 3900 2900 and 1900 Series Integrated Services Routers (ISRs). These low-density Gigabit Ethernet switches offer small to medium-sized business (SMB) and enterprise branch-office customers a combination of switching and routing integrated into a single device.
