Data Sheet Cisco Catalyst 3750 Series Switches ® ® The Cisco Catalyst 3750 Series Switches (Figures 1 through 4) are innovative switches that improve LAN operating efficiency by combining industry-leading ease of use and high ™ resiliency for stackable switches. This product series 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. Figure 1.
Data Sheet Product Overview For midsized organizations and enterprise branch offices, the Cisco Catalyst 3750 Series 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.
Data Sheet Cisco StackWise Technology offers Stackable Resiliency Cisco StackWise technology is a stacking architecture optimized for Gigabit Ethernet. This technology is designed to respond to additions, deletions, and redeployment while maintaining constant performance. Cisco StackWise technology unites up to nine individual switches into a single logical unit, using special stack-interconnect cables and stacking software.
Data Sheet Return on Investment Through Lower Operations Costs The automatic Cisco IOS Software version checking and loading of the global configuration parameters provide the first level of operational time saving. The second level is added during the event of an outage.
Data Sheet services with 802.1x and extensions. This set of comprehensive features not only helps prevent external attacks, but also defends the network against “man-in-the-middle” attacks, a primary concern in today’s business environment. Single IP Management: Many Switches, One Address Each Cisco Catalyst 3750 Series stack is managed as a single object and has a single IP address.

Features and Benefits Feature Ease of Use and Deployment Benefit ● Autoconfiguration of new stack units eliminates reconfiguration. ● Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches through a boot server eases switch deployment. ● Automatic Cisco IOS Software version checking and updating help ensure that all stack members have the same software version.
Data Sheet incorrect fiber-optic wiring or port faults to be detected and disabled on fiber-optic interfaces. ● Switch-port autorecovery (errdisable) automatically attempts to reactivate a link that is disabled because of a network error. ● Cisco RPS 2300 and RPS 675 Redundant Power Systems support provides superior power-source redundancy for up to 6 Cisco networking devices, resulting in improved fault tolerance and network uptime. ● Equal-cost routing for load balancing and redundancy.
Data Sheet ● Weighted Tail Drop (WTD) provides congestion avoidance at the ingress and egress queues before a disruption occurs. ● Strict priority queuing helps ensure that the highest-priority packets are serviced ahead of all other traffic. ● There is no performance penalty for highly granular QoS capability. Granular Rate Limiting ● Cisco committed information rate (CIR) function provides bandwidth in increments as low as 8 Kbps.
Data Sheet access to a server as well as to a portion or all of the network. ● 1000 access control entries (ACEs) are supported. Manageability Superior Manageability ● Cisco IOS Software CLI support provides common user interface and command set with all Cisco routers and Cisco Catalyst desktop switches.
Data Sheet relevant icon in the topology map. ● The user-personalized interface allows modification of polling intervals, table views, and other settings within Cisco CMS Software and retains these settings. ● Alarm notification provides automated e-mail notification of network errors and alarm thresholds. Smartports ● Simple macros help enable advanced QoS features with one command instead of multiple commands in the configuration file.
Data Sheet ● The internal power supply is an autoranging unit. ● The internal power supply supports input voltages between 100 and 240VAC. ● Use the supplied AC power cord to connect the AC power connector to an AC power outlet. ● Cisco RPS Connector ● The connector offers connection for an optional Cisco RPS 2300 or RPS 675 that uses AC input and supplies DC output to the switch.
