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 300-24 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. Secure Desktop Connectivity The Cisco SG 300-24 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 300-24 Switch provides a high level of security and give you fine-grained control to safeguard your network from unauthorised users. Advanced security features include: 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 Unified Communications As a managed network solution, the Cisco SG 300-24 Switch provides the performance and advanced traffic-handling intelligence you need to deliver all communications and data over a single 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. IP Telephony Support Cisco SG 300-24 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. For example, automated voice VLAN capabilities let you plug any IP phone (including third-party phones) into your IP telephony network and receive an immediate dial tone. The switch automatically configures the device with the right VLAN and QoS parameters to prioritise voice traffic. Highly Secure Guest Connectivity A Cisco SG 300-24 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. Optimal Energy Efficiency The Cisco SG 300-24 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. Powersaving features include: 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 Cisco Limited Lifetime Hardware Warranty Cisco SG 300-24 24-Port Switch includes a limited lifetime hardware warranty with next business day advance replacement (where available, otherwise same day ship) and a limited lifetime warranty for fans and power supplies.

ADSL Routers allow multiple users to use your Internet service at the same time so everyone can enjoy high-end Internet functions like streaming video and audio. An ADSL Router will create a local area network, so you can also share files, printers and other network peripherals. Most also provide a much safer internet connection with built-in firewall security preventing unauthorised access of your network from the internet. ADSL routers can only be used via BT's copper phone lines which have been enabled with ADSL broadband. ADSL routers have a built-in ADSL modem, making them a very tidy, one box solution. Most also have built-in Ethernet switches allowing you to connect multiple computers to the router. Should you wish to expand the number of ports, you'll need an additional switch to connect to Terms and Conditions Payment: -We only accept payment by PayPal. -We will ship the item only to a PayPal confirmed address.
