Cisco Small Business Managed Switches

Highlights

• Connects up to 48 network devices - PCs, printers, and servers - to share and transfer
• files and videos across your networkStrong 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 storageSimplified, web-based management for easy installation and configuration

Growing businesses require cost-effective networking solutions that can scale to meet ever-changing business needs. The Cisco1) brings increased intelligence and security to the network infrastructure. The forty-eight 10/100Mbps ports enable you to consolidate your network from several smaller switches or hubs to asingle managed switch. The optional Gigabit optical interfaces allow you to expand the network asyour business grows.Network security is a top priority in any size business. Most business data networks, large andsmall, are unsecured. Unauthorized access to the network and mission-critical data is a constantconcern. The Cisco SRW248G4 helps secure the network through 802.1X port authentication andMAC-based filtering. The 802.1X standard requires clients to authenticate themselves before theport will pass data for them.Businesses are recognizing the benefits of voice over IP (VoIP) and are quickly migrating theirvoice services to IP-based platforms, requiring their local area networks to support both voice anddata applications. In unmanaged IP networks, bursty data sessions can disrupt voice packetdelivery, causing poor voice quality. With the enhanced quality of service (QoS) and traffic-management features in the Cisco SRW248G4, voice data can be prioritized, helping ensure clearand reliable voice communications.

Enabling the advanced features of the Cisco SRW248G4 further secures the integrity of yournetwork. The WebView interface provides an intuitive, highly secure management interface,helping you to better utilize the comprehensive feature set of the switch for a better-optimized,more secure network.

Features
