<P>Available in Standard and Enterprise editions, Catalyst 1900 switches are distinguished by their ease of use, flexible configuration, and upgradability. Standard Edition switches are designed to work directly out of the box and connect desktops to high-speed servers or the network backbone. Enterprise Edition software adds unmatched scalability as well as flexible network configuration options, including virtual LAN (VLAN) support, bandwidth optimization, enhanced security, and comprehensive management capabilities. You can acquire the rich performance and management features of the Enterprise Edition now or later; the software comes preinstalled on the Catalyst 1900 Enterprise Edition switches or is available as an upgrade for Standard Edition switches. </P>
