What does the SE, SE1, SE2 stand for in Cisco switch file names?

*shrug* I assume the SE is just some tag for switch IOS releases which means something like Switch Esomething. The number after the SE is the rebuild number.

The version numbering and letters used for router IOS aren't the same as switch IOS.
