Highly Secure, Reliable Switching with PoE for Small Businesses

Highlights

• Connects up to eight network devices - PCs, printers, and servers - to share and transfer files and videos across your network
• Power over Ethernet easily and cost-effectively powers wireless access points, video cameras, and other network-connected endpoints
  
• 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

Growing businesses require cost-effective networking solutions that can scale to meet ever-changing business needs. The Cisco® SRW208P 8-Port 10/100 Ethernet Switch (Figure 1) brings increased intelligence and security to the network infrastructure. Its intelligence and small size make it ideal for a conference room or training room where security and uptime are important. The switch offers two Gigabit copper or optical interfaces for connection to a core switch.

For wireless or voice over IP (VoIP) deployments, the Cisco SRW208P supports the IEEE 802.3af standard for Power over Ethernet (PoE). Automatic load sensing automatically detects Power over Ethernet on the end device before providing power. Power feeding of Ethernet is limited for the fixed 10BASE-T/100BASE-TX ports. The switch can provide maximum output power per PoE port up to 15.4W on four ports or 7.5W per PoE port on eight ports simultaneously. Each port has independent overload and short-circuit protection, with LED indicators for power status.

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 SRW208P helps 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 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 SRW208P, voice data can be prioritized, helping ensure clear and reliable voice communications. The advanced features of the Cisco SRW208P can help you further secure the integrity of your network. WebView 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.
