CISCO 3750-X Series | 48 Port | 10/100/1000  | PoE+ | IP Base Image | Stackable Data and Power

Cisco 3750 X switches help maximize productivity by giving IT managers the tools needed to support enterprise applications and advanced traffic management. With an array of network modules and redundant power supply options available, these switches can be customized and scaled to support nearly any application. Additional options for the 3750X include Gigabit and 10GE uplink ports, PoE+ and non-PoE support, redundant fans and an array of port densities allow the devices to be tailored and customized. Standard features include StackPower power sharing and StackWise Plus logical port aggregation (64Gbps of through put). Software upgrades include multicast routing, IPv4 and IPv6 support and advanced QoS (Quality of Service). Hardware security, Cisco Energywise power management and type A and B USB interfaces are also standard. These feature rich, fixed configuration devices are the switch of choice for medium to enterprise business looking to maximize IT budgets while maintaining rich functionality and a borderless experience.StackPower is a innovative power sharing and redundancy technology available on the Cisco 3750-X series of switches. You can interconnect up to (4) 3750X’s in series using the CAB-SPWR-xxxCM cable. This configuration allows members of the stack to share in one of two power pooling topologies. The first, power sharing mode, aggregates then distributes the power among the stack. Power is dynamically allocated where its needed. The second, redundant mode, polls the stack, identifies the supply with the greatest wattage then reserves its use for failure. Power is then allocated to the stack from the remainder of the supplies. Once the reserved power supply is activated, the stack migrates to power sharing mode automatically. This technology eliminates the need for an external RPS unit and allows users to simply add another power supply for either redundancy or additional power to the pool. StackWise Plus improves upon the established stacking architecture, StackWise. This technology allows up to 9 switches, or (432) 10/100/1000 ports, to be logically aggregated and managed using a single IP address, command line or telnet session. In addition, StackWise Plus is backwards compatible with older 3750 and 3750-E switches running standard StackWise while maintaining an increased throughput of 64Gbps. PoE+ (or builds on the legacy of Cisco’s industry leading PoE ( and Inline Power legacy. This new power delivery method allows 30W of power per port to PD’s (Powered Devices) as opposed to 15.4W with standard PoE. This decreases deployment costs and TCO by eliminating the need for power runs to the PD instillation location. Automatic power negotiation manages power consumption and keeps wattage transmission from the switch at the appropriate levels eliminating electrical waste.  In addition, PoE+ devices are backwards compatible with older PoE 802.3af, so you get the best of both worlds!   The 3560-X and 3750-X series of switches are also equipped with a network module slot that accepts one of four optional modules for up-linking. With a combination of copper, SFP and SFP+ support these modules continue to lower the TCO and add the flexibility and investment protection you need. This 3750X-48P-S has 48, 10/100/1000 PoE+ auto-sensing ports and (1) NM slot. The  WS-C3750X-48P-S will enhance productivity and lower cost by giving users controlled, managed and highly available access to the applications and borderless experience that drives today’s communication.  Quick Specs:
