3750X 'show version'

I did a show version on a 3750X, and the software image is 3750E.  Can someone explain this?  So...3750X runs 3750E, but just has stackpower?  Shouldn't it say software image 3750X instead of 3750E?

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

No it's correct. The E is a universal image across all versions of 3750-X.

Like my esteemed colleague said, it's a universal image.

When you look for software images for a 3750x at Cisco, you can see this:

The 3750e refers to the software image, 3750x refers to the hardware.

When you look closely at the show version, you should also see the hardware in there:
