Main differences between lines of Cisco 3750 Series Switches


10/100/1000 Port Availability

The 3750V2 series does not have a 10/100/1000 model. All port configurations are either 24-port 10/100 or 48-port 10/100. Gigabit is only offered through 2 or 4 SFP ports. The 3750V1 series offered a wide variety of 10/100/1000 port options. If you want 10/100/1000 port density then skips over the 3750V2 series and goes with the 3750-E or 3750-x series.


Cisco StackPower combines all the individual power supplies installed in the switches and creates a pool of power, directing that power where it is needed. Up to four switches can be configured in a StackPower stack. StackPower cables use their own special cables and connect in the same way as the popular StackWise cables.

Dual Redundant Power Module Supplies

The Cisco 3750-X supports two hot swappable power supplies. The switch ships with one power supply by default. The second power supply can be purchased at the time of the order or later. I’ve found that in 3750-X stacks going with one power supply works great when combined with StackPower. It saves money and reduces power consumption.

Network Modules

There are four network modules for the 3750-X. Each provides a combination of GbE or 10GbE interfaces. For upgrade protection and scalability. The 3750-E supports the TwinGig SFP converter. This enables an upgrade path from 1GbE to 10GbE.


StackWise technology allows a group of 3750 switches to be “stacked” together using StackWise cables. This stacking of switches basically combines them into one functional unit providing much higher levels of redundancy and capacity while providing investment protection

Built on StackWise technology, StackWise Plus offers several improvements in speed and performance. StackWise Plus offers 64Gbps backplane across the StackWise cables (backplane). Up to nine switches can be in the stack.


Cisco EnergyWise is an innovative architecture, added to fixed configuration 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. 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.
