Cisco SRW248G4

Description
The Cisco SRW248G4 48-port 10/100 + 4-port Gigabit switch 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 a single managed switch. Network security is a top priority in any size business. Most business data networks, large and small, are unsecured. Unauthorized access to the network and mission-critical data is a constant concern. The Cisco SRW248G4 helps secure the network through 802.1x port authentication and MAC-based 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 SRW248G4, voice data can be prioritized, helping ensure clear and reliable voice communications. Enabling the advanced features of the Cisco SRW248G4 further secures the integrity of your network. 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.
