The new Cisco Catalyst 3750-48TS switch is an innovative product that improves LAN operating efficiency by combining industry-leading ease of use and the highest resiliency available for stackable switches. This new product represents the next generation in desktop switches, and features Cisco StackWise technology, a 32-Gbps stack interconnect that allows customers to build a unified, highly resilient switching system, one switch at a time. For mid-sized organizations and enterprise branch offices, the Cisco Catalyst 3750-48TS eases deployment of converged applications and adapts to changing business needs by providing configuration flexibility, support for converged network patterns, and automation of intelligent network-services configurations. In addition, the Cisco Catalyst 3750-48TS is optimized for high-density Gigabit Ethernet deployments and includes a diverse range of switches that meet access, aggregation, or small-network backbone-connectivity requirements.
