CISCO ETHERSWITCH 4PORT HIGH-SPEED WAN INTERFACE CARDS FOR CISCO 1800 (MODULAR), CISCO 2800, AND CISCO 3800 SERIES INTEGRATED SERVICES ROUTERSThe 4port Cisco EtherSwitch 10/100 high-speed WAN interface cards (HWICs) supported on the Cisco 1800 (modular), Cisco 2800, and Cisco 3800 series integrated services routers offer small-to-large-size businesses and enterprise branch officecustomers the option to integrate switching and routing in one device. This combination offers ease of configuration, deployment, and management while using the powerful characteristics of Cisco routing and Cisco Catalyst switching features.The modular 4port Cisco EtherSwitch HWICs provide line-rate Layer 2 switching acrossEthernet ports using Cisco IOS Catalyst Software. The 4-port Cisco Ether Switch HWIC has four 10/100 switched Ethernet ports, with options for inline power support on all four ports. The ninth port does not support inline power but can be used as a regular switch port for trucking and other normal data applications. Note: The optional inline power support on the 4port HWICs is offered on the Cisco2800 and Cisco 3800 series. It is not offered on the Cisco 1841 of the Cisco 1800 Series (modular). Features such as port auto sensing, quality of service (QoS), VLAN support from 802.1P and 802.1Q standards, and 802.1D spanning tree protocols are standard on the Cisco EtherSwitch HWIC. The Cisco EtherSwitch HWICs are available in standard 4port 10/100BASE-TX switch HWIC and Power-over-Ethernet (PoE) configurations. The PoE configurations consist of a 4port 10/100BASE-TX switch and a 4port inline power module daughter card. The power module daughter card houses a power controller for detecting, classifying, and enabling power on 802.3af-compliant powered devices attached to the HWICs. The inline powered version of the Cisco EtherSwitch HWIC can power Cisco IP phones, Cisco wireless access points, or any other IEEE 802.3af-compliant device. The optional inline power support on the 4port HWICs on the Cisco 2800 and Cisco 3800 series of integrated services routers requires the use of a field-replaceable inline power supply.
