SRW2048-K9-EU
Brand name: CISCO SRW2048-K9-EU
Model: SRW2048-K9-EU
Short Description: Small businesses require cost-effective yet scalable networking solutions that can meet changing business needs. The Cisco SRW2048 48-Port Gigabit Switch brings Gigabit speeds to your users and servers, while increasing the intelligence and security of the network infrastructure.
The forty-eight 10/100/1000 Mbps ports enable you to take advantage of the Gigabit Ethernet interfaces shipping in the current generation of servers, workstations, and storage devices, in addition to supporting your existing 10/100 Mbps clients.
Network security is a top priority in any size business. Most business data networks, large and small, are unsecure. Unauthorized access to the network and mission-critical data is a constant concern. The Cisco SRW2048 helps secure the network by using 802.1X port authentication, access control lists (ACLs), and MAC addresses port locking. 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 QoS and traffic management features in the Cisco SRW2048, voice data can be prioritized, helping ensure clear and reliable voice communications.Taking advantage of the advanced features of the Cisco SRW2048 can further secure 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.

High performance and reliability
All Cisco SF 300-08 8-Port Ethernet Switches have been rigorously tested to deliver the high availability and performance you expect from a Cisco switch. 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 SF 300-08 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 SF 300-08 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 SF 300-08 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 SF 300-08 Switch provides the performance and advanced traffic-handling intelligence you need to deliver all communications and data over a single network.
