Mix 3750 and 3750-E's in the same stack?

Is it possible to mix the two types of switches in the same stack? Can I insert a 3750-E into an existing stack of 3750 switches? Will I lose any functionality?

Hi,

yes you can but it reduces the stackwise capabilities, please see the following

Q. Can I run Cisco Catalyst 3750 switches with Cisco Catalyst 3750-E switches in the same stack?

A. Yes, the two series are compatible. When the Cisco Catalyst 3750-E Series detects a non-E-Series Cisco Catalyst 3750, it will negotiate down from StackWise Plus mode to StackWise mode. Thus, the entire stack will now run in the original StackWise mode.

It will work. Just make sure the 6750 and 3750-E are running the same IOS version and the same feature set.
