Product Overview

The new Cisco Catalyst 4500 Series Line Card can support up to 30 watts per port of inline power in addition being ready to support PoE Plus. It also supports Cisco Enhanced PoE, IEEE 802.3af PoE, and the Cisco prestandard PoE implementations with a maximum of 750 watts per line card. It is designed to power IP phones, wireless base stations, video cameras, and other PoE devices. The new higher-wattage inline power offers you greater flexibility and mobility with support for new devices, services, and applications, while support for older power levels ensures backward compatibility with existing Cisco powered devices.
The line card enhances the Cisco Catalyst 4500 Series portfolio by giving you the flexibility to support high-wattage inline power using a classic line card. Similar capability is currently available on the Catalyst 4500 E Series Premium PoE 10/100/1000 linecard (WS-X4648-RJ45V+ E).
The new line card has optional power classifications and intelligent power-management features. These line-card capabilities combined with standard Cisco Catalyst 4500 Series features such as In-Service Software Upgrades (ISSU) make it an ideal platform for collaboration applications, including mission-critical applications such as IP telephony and support for nonstop application delivery.
The line card is compatible with all Cisco Catalyst 4500 Series chassis, and you can deploy it with any supervisor engine, helping ensure maximum investment protection. The Cisco Catalyst 4500 Series power supplies and accessories enable the line card to support high-density PoE deployments. You can calculate detailed power consumption and scalability information for specific configurations using the Cisco Power Calculator, available at:
