Cisco Catalyst 3750v2 Series Fixed-configuration switches offering multilayer switching and Cisco StackWise™ technology for enterprise branch offices and mid-market organizations. The Cisco Catalyst 3750v2 Series is an innovative line of multilayer Fast Ethernet switches featuring Cisco StackWise technology, a 32 Gbps stack interconnect that allows customers to build a unified, highly resilient switching system-one switch at a time. Up to nine Catalyst 3750v2 Series switches can be stacked in any combination, enabling organizations to mix and match to meet specific requirements. Additional 10/100, and Power over Ethernet (PoE) connectivity can be deployed as necessary, offering a simple and cost-effective pay-as-you-go approach to network upgrades. The Catalyst 3750v2 Series can be purchased with the IP Base or IP Services licenses. The IP Base license offers advanced QoS, rate-limiting, ACLs, and basic routing functionality. The IP Services license provides a richer set of enterpriseclass features, including advanced hardware-based IP Unicast and IP Multicast routing as well as Policy-based Routing (PBR), IPv6 routing and and advanced IP services. Cisco Catalyst 3750v2 Series Spotlight Cisco StackWise Technology A unique stacking architecture, this technology is designed to respond to additions, deletions, and redeployment while maintaining constant performance. It unites up to nine individual Catalyst 3750V2 switches into a single logical unit, using special interconnect cables and stacking software. The stack is managed as a single switching unit controlled by a master switch elected from one of the member switches. The master switch automatically creates and updates all the switching and routing tables. A working stack can accept new members or delete old members without service interruption. Addition of IP Communications Cisco Catalyst 3750V2 Series PoE models support Cisco IP phones and Cisco Aironet® wireless LAN (WLAN) access points, as well as any IEEE 802.3af- compliant end device. The Catalyst 3750V2 24-port models can support 24 simultaneous full-powered PoE ports at 15.4W for maximum powered device support. The 48-port versions can deliver the necessary power to support 24 ports at 15.4W, 48 ports at 7.3W, or any combination in between. 191
