Product Overview

Small businesses require cost-effective yet scalable networking solutions that can meet changing
business needs. The Cisco® SRW2048 48-Port Gigabit Switch (Figure 1) 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. 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. 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 better­optimized, more secure network.
