All Cisco SG 300-20 16-Port Gigabit Ethernet Switches have been rigorously tested to deliver the high availability and performance you expect from a Cisco switch. The solutions speed up file transfer times and improve slow, sluggish networks, while keeping your vital business applications available and preventing costly downtime. As a managed switching solution, the Cisco SG 300-20 also gives you the flexibility to manage and prioritise high-bandwidth traffic such as voice. That means you can empower your employees with state-of-the-art communication and productivity solutions, without draining the performance of your other business applications.
The Cisco SG 300-20 Switch can simply and securely connect employees working in small offices with each other and with all of the servers, printers, and other devices they use. High performance and reliable connectivity helps speed file transfers and data processing, improves network uptime, and keeps your employees connected and productive. Additionally, the Cisco SG 300-20 Switch provides a high level of security and give you fine-grained control to safeguard your network from unauthorised users.
Embedded security to protect management data traveling to and from the switch and encrypt network communications. Extensive access control lists (ACLs) to restrict sensitive portions of the network from unauthorised users and guard against network attacks. Guest virtual LANs (VLANs) to let you provide Internet connectivity to nonemployee users while isolating critical business services from guest traffic. Support for advanced network security applications such as IEEE 802.1X port security to tightly limit access to specific segments of your network. Cisco offers a complete portfolio of IP telephony and other unified communications products designed for small businesses.Cisco SG 300-24 Switchs have been rigorously tested to help ensure easy integration and full compatibility with these and other products, providing a complete small business solution. Cisco SG 300-20 Switches include embedded QoS intelligence to prioritise delaysensitive services such as voice and video, simplify unified communications deployments, and help ensure consistent network performance for all services. The switch automatically configures the device with the right VLAN and QoS parameters to prioritise voice traffic. A Cisco SG 300-20 Switch let you extend highly secure network connectivity to guests in a variety of settings, such as a hotel, an office waiting room, or any other area open to nonemployee users. Using powerful but easy-to-configure security and traffic segmentation capabilities, you can isolate your vital business traffic from guest services and keep guests' network sessions private from each other.
The Cisco SG 300-20 Switch is designed with a variety of power-saving features across all models, providing the industry's broadest portfolio of "green" switches. These Cisco SG 300-24 Switches optimise power use to protect the environment and reduce energy costs, without compromising performance. The latest application-specific integrated circuits (ASICs), using low-power 65-nanometer technology (these chipsets allow for lower power consumption and thinner, more efficient designs).
Embedded intelligence to adjust signal strength based on cable length. Fanless design in most models, which reduces power consumption, increases reliability, and provides quieter operation.
