Cisco SRW224G4 24-Port 10/100 + 4-Port Gigabit Switch: WebView Cisco Small Business Managed Switches Secure, Reliable, Intelligent Managed Switching for Your Growing Business Highlights ● Connects up to 24 network devices - PCs, printers, and servers - to share and transfer files and videos across your network ● Strong security protects network traffic to keep unauthorized users off the network ● Intelligent QoS helps ensure a consistent network experience and supports networked applications including voice, video, and data storage ● Simplified, web-based management for easy installation and configuration Product Overview Growing businesses require cost-effective networking solutions that can scale with ever-changing business needs. The Cisco(r) SRW224G4 24-Port 10/100 + 4-Port Gigabit Switch (Figure 1) brings a new level of intelligence and security to the network infrastructure. The twenty-four 10/100 Mbps ports enable you to consolidate your network from several smaller switches or hubs to a single managed switch. The optional Gigabit optical interfaces allow you to expand the network as your business grows. Network security is a top priority in any size business. Unauthorized access to the network and mission-critical data is a constant concern. The Cisco SRW224G4 is able to secure the network through 802.1X port authentication and MAC filtering. The 802.1X standard requires clients to authenticate themselves before the port will pass data for them. Businesses are recognizing the benefits of voice over IP (VoIP) and are quickly migrating their voice services to IP-based platforms, requiring their local area networks to support both voice and data applications. In unmanaged IP networks, bursty data sessions can disrupt voice packet delivery, causing poor voice quality. With the enhanced quality of service (QoS) and traffic management features in the Cisco SRW224G4, voice data can be prioritized, helping ensure clear and reliable voice communications. Enabling the advanced features of the Cisco SRW224G4 further secures the integrity of your network. The WebView interface provides an intuitive, highly secure management interface, enabling you to better utilize the comprehensive feature set of the switch, for a better-optimized, more secure network.
