The Cisco WS-C3750G-12S-S switch is a stackable multilayer switch that improves LAN efficiency and resiliency. It uses Cisco StackWise technology, a 32-Gbps stack interconnect which lets customers build a unified and highly resilient switching system. It is ideal for mid-sized organizations and enterprise branch offices that need to deploy converged applications and adapt to changing business needs. It offers configuration flexibility, automation of intelligent network-services configurations, and support for converged network patterns. It also supports high-density Gigabit Ethernet deployments with 12 SFP-based Gigabit Ethernet ports. • It has 12 Gigabit Ethernet ports that use SFP modules • It has a 32-Gbps stack interconnect for stacking technology • It is a 1 RU stackable multilayer switch • It delivers enterprise-class intelligent services to the network edge • It runs on the IP Base software feature set (IPB)
