Cisco 9-Port 10/100 Ethernet Switch HWIC with 8-Port Inline Power Daughter Card

The Cisco 9-port EtherSwitch HWICs provide line-rate Layer 2 switching across Ethernet ports using Cisco IOS Catalyst Software. The 9-port Cisco EtherSwitch HWIC has nine 10/100 switched Ethernet ports, with options for inline power support on 8 of the 9 ports. The ninth port does not support inline power but can be used as a regular switch port for trunking and other normal data applications. Features such as port autosensing, 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 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 9-port HWICs on the Cisco 2800/2900 and Cisco 3800/3900 series of integrated services routers requires the use of a field-replaceable inline power supply.

The 9-port Cisco EtherSwitch HWICs when combined with analog or digital voice modules for the Cisco Integrated Services Routers provide a small-to-large enterprise branch office infrastructure for IP telephony deployments. This solution can be combined with Cisco CallManager Express IP Telephony or the Cisco IOS Software Survivable Remote Site Telephony (SRST) solution.

SRST runs on the local branch office router, allowing it to automatically detect a failure in the network and initiates a process to intelligently auto configure the router to provide call-processing backup redundancy for the IP phones in that office. In the case of a Cisco CallManager Express deployment, call-processing features are offered on the branch router without a centralized call manager.

The Cisco EtherSwitch HWIC with the optional internal chassis provides IP phone power and phone discovery for IP phones. In addition, the Cisco EtherSwitch HWIC supports separate VLAN configuration for IP phones. The auxiliary VLAN feature allows network administrators to segment phones into separate logical networks, even though the data and voice infrastructures are physically the same. The phone discovery feature allows the Cisco 9-port EtherSwitch HWICs (product numbers HWIC-4ESW-POE or HWIC-D-9ESW-POE) to automatically detect the presence of an IP phone and supply inline power.
