The Cisco Catalyst 3750-48TS switch is a member of the Cisco Catalyst 3750 Series, an innovative product line that improves LAN operating efficiency by combining industry-leading ease of use and the highest resiliency available for stackable switches. This new product series 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. Using a 32-Gbps stack interconnect, Cisco StackWise technology is designed to respond to network changes of all kinds while maintaining constant high network performance. Cisco StackWise technology unites up to nine Catalyst 3750 switches into a single logical unit via special stack interconnect cables. The stack behaves as a single unit managed by a master switch elected from one of the member switches. Its advanced failover mechanisms create the highest levels of stackable resiliency for hardware and software reliability.
