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. The individual 

switches can be any combination of Cisco Catalyst 3750 and Cisco Catalyst 3750-E Series 

Switches. 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. 

Cisco EnergyWise is an innovative architecture, added to the Cisco Catalyst 3750 switches, 

promoting companywide sustainability by reducing energy consumption across an entire corporate 

infrastructure and affecting more than 50 percent of global greenhouse gas emissions created by 

worldwide building infrastructure, a much greater effect than the 2 percent generated by the IT 

industry. Cisco EnergyWise enables companies to measure the power consumption of network 

infrastructure and network-attached devices and manage power consumption with specific policies, 

reducing power consumption to realize increased cost savings, potentially affecting any powered 

device.  

EnergyWise encompasses a highly intelligent network-based approach to communicate messages 

that measure and control energy between network devices and endpoints. The network discovers 

Cisco EnergyWise manageable devices, monitors their power consumption, and takes action 

based on business rules to reduce power consumption. EnergyWise uses a unique domain-naming 

system to query and summarize information from large sets of devices, making it simpler than 
traditional network management capabilities. Cisco EnergyWise’s management interfaces allow 

facilities and network management applications to communicate with endpoints and each other 

using the network as a unifying fabric. The management interface uses standard SNMP or SSL to 

integrate Cisco and third-party management systems. 

Cisco EnergyWise extends the network as a platform for the power control plane for gathering, 

managing, and reducing power consumption of all devices, resulting in companywide optimized 

power delivery and reduced energy costs. 

A working stack is self-managing and self-configuring. When switches are added or removed, the 

master switch automatically loads the Cisco IOS

®

 Software revision running on the stack to the new 

switch, loads the global configuration parameters, and updates all the routing tables to reflect 

changes. Upgrades are applied universally and simultaneously to all members of the stack. 

The Cisco Catalyst 3750 Series stacks up to nine switches as a single logical unit for a total of 468 

Ethernet or PoE 10/100 ports, or 468 Ethernet 10/100/1000 ports or PoE 10/100/1000 ports, or 

nine 10 Gigabit Ethernet ports. Additional port combinations can be created by connecting the 

Cisco Catalyst 3750-E Series Switches to the stack. Individual 10/100, 10/100/1000, and 10 Gigabit 

Ethernet units can be joined in any combination to evolve with network needs.
