– Enhanced limited lifetime warranty (LLW) with next business day (NBD) advance hardware replacement and 90 day access to Cisco Technical Assistance Center (TAC) support
– Enhanced Cisco EnergyWise for operational cost optimization by measuring actual power consumption of the PoE devices, reporting, and reducing energy consumption across the network
– USB Type-A and Type-B ports for storage and console respectively and an out-of-band Ethernet management port
In addition to the above features, the Cisco Catalyst 3750-X switches also offer:

– Cisco StackPower? technology: An innovative feature and industry first for sharing power among stack members
– Cisco StackWise Plus technology for ease of use and resiliency with 64 Gbps of throughput
– Investment protection with backward compatibility with all other models of Cisco Catalyst 3750 Series Switches

Cisco StackWise Plus technology is built on the highly successful industry leading StackWise technology, which is a premium stacking architecture optimized for GbE. StackWise technology was designed to respond to additions, deletions, and redeployment while maintaining constant performance. The stack behaves as a single switching unit that is managed by a master switch elected from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables. A working stack can accept new members or delete old ones without service interruption. StackWise creates a highly resilient single unified system of up to nine switches, providing simplified management using a single IP address, single telnet session, single command-line interface (CLI), auto-version checking, autoconfiguration, and more. StackWise Plus supports all the features of StackWise and provides backward compatibility with the existing Cisco Catalyst 3750 Series Switches while enhancing the throughput of the system up to 64 Gbps. StackWise Plus also enables local switching in Cisco Catalyst 3750-X Series Switches. Local switching packets coming into a port in the Cisco Catalyst 3750-X Series or 3750-E Series Switch destined for another port in the same switch do not have to traverse through the stack ring, thus increasing the forwarding capacity of the switch. The Cisco Catalyst 3750-X Series stacks up to nine switches as a single logical unit for a total of 432 Ethernet 10/100/1000 ports with 18 10GbE ports. Individual 10/100/1000 units can be joined in any combination to evolve with network needs.
