The Cisco Catalyst 3560 Series switches is a line of fixed configuration, enterprise-class, IEEE 802.3af and Cisco prestandard Power over Ethernet (PoE) switches in Fast Ethernet configurations that provide availability, security, and quality of service (QoS) to enhance network operations. The Catalyst 3560 is an ideal access layer switch for small enterprise wiring closets or branch office environments that are using their LAN infrastructure for the deployment of new products and applications such as IP telephones, wireless access points, video surveillance, building management systems, and remote video kiosks. Customers can deploy network-wide intelligent services, such as advanced QoS, rate limiting, access control lists, multicast management, and high-performance IP routing - while maintaining the simplicity of traditional LAN switching.

The standard multilayer software image (SMI) feature set includes advanced QoS, rate-limiting, ACLs, and basic routing functionality.

Successor of the EF300mm f/2.8L USM, this is a next-generation wide aperture 300mm lens with a newly designed optical system to achieve even better image quality. Its one fluorite lens and two UD lenses completely eliminate secondary spectrum. It offers super high image quality with both resolution and contrast higher than ever before. And the image stabilizer that equals about 2 shutter speed steps maximizes the performance of the lens under all photgraphy conditions. Its autofocusing is the fastest in the world (when used with an EOS-3), thanks to a ring USM and improved drive algorithm. Closest focusing distance has been reduced to 2.5m, while operatibility has been substantially improved by full time mechanical manual focus, improved focus preset, and the introduction of an AF Stop function. The lens's super light design includes a magnesium alloy lens barrel and it offers good dust-proof and moisture-proof performance even under harsh conditions.

The xStack DGS-3450 next generation switch delivers performance, flexibility, security, multi-layer Quality of Service (QoS) and redundant power option for the SMB and enterprises. With high Gigabit port densities for desktop connections, SFP fibre connectivity, 10-Gigabit uplink options and enhanced Layer 2+ functions, this switch comprises the workgroup access-layer stack for seamless integration with L3 core switches to form part of a multilevel network structured with high-speed backbone and centralized servers.

The DGS-3450 can operate as a stand-alone device or part of a scalable stack. Embedded with Single IP Management capability, a stand-alone switch can form part of a virtual stack, where intra-stack traffic flows through the usual network wires, doing away with the costly stacking cables. Without stacking cables, cable distance barriers and physical stacking limitations, a virtual stack can comprise units that are located anywhere on the network that minimizes the impact of any single point of failure.

Alternatively, optional 10-Gigabit modules can be installed in the open slots to create a physical stack. Up to 12 units or 576 Gigabit ports can be configured for a stack. Users can install one or two single-port modules, depending on whether the fault-tolerant Ring or Star stacking is implemented. With each of these ports providing 20Gbps full duplex transmission on the cost-effective coaxial cable, the DGS-3450 provides not only high-bandwidth stacking but also cost control capability that allows users to add ports strictly on a per need basis. Modules with single 10-Gigabit XFP can also be installed in any of the open slots for uplink to a server or a fibre backbone.

The DGS-3450 provides a complete set of security features, which includes L2/L3/L4 multi-layer Access Control Lists and 802.1x user authentication via TACACS+ and RADIUS servers. In addition, it offers suppression capabilities, Layer 3 IP v.4/v.6 Static Routing and IP v.6 tunnelling to increase network performance and security. To ensure that not only proper user access is served, but also malicious traffic within the network is prevented, the DGS-3450 includes a Health Check mechanism that provides pro-active network security without the need for manual intervention from the administrator.

The DGS-3450 provides extensive VLAN support including GARP/GVRP, 802.1Q and asymmetric VLAN to enhance security and performance. To support converged applications including VoIP, ERP, Intranet and videoconference, a robust set of L2/L3/L4 QoS/CoS features ensures that critical network services are served with proper priority. With Multi-layer L2/L3/L4 bandwidth control and D-Link Safeguard Engine, the DGS-3450 can set limits to traffic flows from the edge of the network while automatically prevents broadcast packets and bulk traffic generated by Internet Dos-related activities from utilizing the switch's CPU resources. This prevention of unnecessary and harmful traffic can increase the overall network serviceability, reliability and availability of the stack.
