The Cisco Catalyst 3550-24 PWR inline power switch is a stackable, multilayer, 24-port 10/100 switch with 2 Gigabit Interface Converter (GBIC)-based Gigabit Ethernet ports ideal for integrated voice, video, and data applications. With integrated inline power, customers can power Cisco IP phones and Cisco Aironet wireless LAN access points directly from the switch and lower the total cost of ownership (TCO) by:

• Centralizing power provisioning
• Easing deployment by eliminating the need for wall power to each device
• Eliminating the need for additional, separate wiring to power devices

The Catalyst 3550-24 PWR switch possesses all of the advanced Layer 2-4 intelligent services available in the Catalyst 3550 Series. Customers can deploy high-performance IP routing, advanced quality of service (QoS), granular rate-limiting, enhanced network security, and multicast management network-wide-while maintaining the simplicity of traditional LAN switching.

With a range of Fast Ethernet and Gigabit Ethernet configurations, the Catalyst 3550 Series can serve as both a powerful access layer switch for medium enterprise wiring closets, as a backbone switch for mid-sized networks, and also for the edge of metro access networks. Additionally, with the Catalyst 3550 24 PWR, up to 15.4W/port of inline power on every 10/100 port ensures maximum device support for IP telephony and wireless LAN deployments.

Maximum power availability for a converged voice and data network is attainable when the Catalyst 3550-24 PWR switch is combined with the Cisco Redundant Power System 675 (RPS 675) for seamless protection against internal power supply failures and an uninterruptible power supply (UPS) system to safeguard against power outages.

The Catalyst 3550-24 PWR is installed with either the Standard Multilayer Software Image (SMI) or the Enhanced Multilayer Software Image (EMI). The SMI feature set includes advanced QoS, rate-limiting, access control lists (ACLs), and basic static and RIP routing functionality. The EMI provides a richer set of enterprise-class services including advanced hardware-based IP unicast and multicast routing and the Web Cache Communication Protocol (WCCP). Switches installed with SMI have the flexibility to upgrade to EMI with the Enhanced Multilayer Software Image upgrade kit (CD-3550-EMI=). This product comes with the SMI image installed.

Available for the Catalyst 3550 Series, the Cisco Network Assistant is a free centralized management application that simplifies the administration task of Cisco switches, routers, and wireless access point. Cisco Network Assistant offers user-friendly GUI interface to easily configure, troubleshoot, and enable and monitor the network. The Catalyst 3550-24 PWR provides:

• 24 10/100 ports and 2 1000BASE-X Gigabit Ethernet ports
• 1 RU stackable, multilayer switch; integrated inline power
• Delivers enterprise-class intelligent services to the network edge
• SMI installed, upgradeable to EMI with full, dynamic IP routing
• Ideal for access and distribution layer connectivity
• Part number: WS-C3550-24PWR-SMI
