The Cisco Catalyst® 3750G-12S 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.
