Cisco catalyst 3750-X vs. 3560-X, Cisco 3750E vs. 3750X series, Cisco 3750-X vs. 3850-Series, What are the differences? These Cisco 3750-X comparison questions often comes up for discussion. Maybe we know a little brief difference, for example, the catalyst 3750 supports Cisco StackWise, can create one large virtual switch out of multiple chassis. And Cisco 3560 has a “cluster” feature, which means that you can control multiple switches from a single one.

In this article, we will mainly compare the Cisco 3750-E series to Catalyst 3750-X. We know that the “X” offers what Cisco is calling StackPower, the ability to share power loads between multiple switches. This is a beneficial feature when it comes to PoE+. StackPower allows up to four members of the same StackWise group to combine their power supplies into one large virtual power supply. It also allows some of the power supplies to be taken offline, increasing efficiency.

For building out small to medium offices these two features are quite valuable. Start with one switch and add on with little to no disruption, while only using the power needed.

Note: One exception is the new LAN Base models being introduced with the Cisco Catalyst 3750-X Series, which can stack only with other Catalyst 3750-X LAN Base models. Cisco Catalyst 3750-E and Catalyst 3750-X StackWise Plus and Cisco Catalyst 3750 StackWise switches can be combined in the same stack. When this happens, the Cisco Catalyst 3750-E, or Catalyst 3750-X switches negotiate from StackWise Plus mode down to StackWise mode.

After we got a general impression on Cisco 3750-X series, let’s come to Cisco Catalyst 3750-E Series’ highlights.
