<P>The 3Com<SUP>?</SUP> CoreBuilder<SUP>?</SUP> 9000 enterprise switch represents a new class of LAN switch that enables IT managers to deliver a higher level of service in increasingly demanding environments, while, at the same time, lowering the operational costs of that network asset. </P><P> The CoreBuilder 9000 switch gives IT managers a common platform that they can deploy (in different chassis sizes) across the enterprise LAN to deliver low-cost, high-density work-group access, ensure high-speed, resilient server connectivity, and create powerful, efficient back-bone interswitch links. A common platform reduces staff training and administrative overhead, and lowers maintenance costs and inventory management (by enabling redeployment and sharing of chassis interface modules). </P>
