The Cisco Catalyst 3560 Series can be purchased with the IP Base or IP Services licenses pre-installed. The IP Base license (formerly called the

Standard Multilayer Image, or SMI) offers advanced QoS, rate limiting, ACLs, and basic static and Routing Information Protocol (RIP) routing

functions. The IP Services license (formerly called the Enhanced Multilayer Image, or EMI) provides a richer set of enterprise-class features,

including advanced hardware-based IP unicast and IP Multicast routing as well as policy-based routing (PBR). The Advanced IP Services license,

although not available as a pre-installed option, upgrades Catalyst 3560 Series switches to include IPv6 routing and IPv6 ACL support. Upgrade

licenses are available to upgrade a switch from the IP Base license to the IP Services license or Advanced IP Services license as well as from the

IP Services license to the Advanced IP Service license.

The SFP-based GE ports accommodate a range of SFP transceivers, including the Cisco 1000BASE-T, 1000BASE-SX, 1000BASE-LX, 1000BASE-

ZX, and CWDM SFP transceivers. These ports also support the Cisco Catalyst 3560 SFP Interconnect Cable for establishing a low-cost Gigabit

Ethernet point-to-point connection.

POWER OVER ETHERNET

The Cisco Catalyst 3560 Series can provide a lower total cost of ownership (TCO) for deployments that incorporate Cisco IP phones, Cisco Aironet

wireless LAN (WLAN) access points, or any IEEE 802.3af-compliant end device. PoE removes the need for wall power to each PoE-enabled device

and eliminates the cost for additional electrical cabling that would otherwise be necessary in IP phone and WLAN deployments. The Cisco Catalyst

3560 24-port PoE configurations can support 24 simultaneous full-powered PoE ports at 15.4W for maximum powered-device support. Taking

advantage of Cisco Catalyst Intelligent Power Management, the 48-port PoE configurations can deliver the necessary power to support 24 ports at

15.4W, 48 ports at 7.7W, or any combination in between. Maximum power availability for a converged voice and data network is attainable when

a Cisco Catalyst 3560 switch is combined with the Cisco RPS 675 Redundant Power System for transparent protection against internal power supply

failures and an uninterruptible power supply (UPS) system to safeguard against power outages.

GIGABIT ETHERNET

At speeds of 1000 Mbps, Gigabit Ethernet provides the bandwidth to meet new and evolving network demands, alleviate bottlenecks, and boost

performance while increasing the return on existing infrastructure investments. Today’s workers are placing higher demands on networks, running

multiple, concurrent applications. For example, a worker joins a team conference call through an IP videoconference, sends a 10-MB spreadsheet to

meeting participants, broadcasts the latest marketing video for the team to evaluate, and queries the customer-relationship-management database for

the latest real-time feedback. Meanwhile, a multigigabyte system backup starts in the background and the latest virus updates are delivered to the

client. The Cisco Catalyst 3560 provides a means to intelligently scale the network beyond 100 Mbps over existing Category 5 copper cabling and

simultaneously support PoE for maximum productivity and investment protection.

INTELLIGENCE IN THE NETWORK

Networks of today are evolving to address four new developments at the network edge:

• Increase in desktop computing power

• Introduction of bandwidth-intensive applications

• Expansion of highly sensitive data on the network

• Presence of multiple device types, such as IP phones, WLAN access points, and IP video cameras

These new demands are contending for resources with many existing mission-critical applications. As a result, IT professionals must view the edge of

the network as critical to effectively manage the delivery of information and applications.

As companies increasingly rely on networks as the strategic business infrastructure, it is more important than ever to ensure their high availability,

security, scalability, and control. By adding Cisco intelligent functions for LAN access, customers can now deploy networkwide intelligent services

that consistently address these requirements from the desktop to the core and through the WAN.

With Cisco Catalyst Intelligent Ethernet switches, Cisco Systems

helps enable companies to realize the full benefits of adding intelligent services

into their networks. Deployment of capabilities that make the network infrastructure highly available to accommodate time-critical needs, scalable
