These are the procedures for downloading software. Before downloading software, read this section for 
important information:

The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release. A 
subdirectory contains the files needed for web management. The image is stored on the system board 
flash device (flash:).

You can use the show version privileged EXEC command to see the software version that is running on 
your switch. The second line of the display shows the version.

For Catalyst 3750 and 3560 switches and the Cisco EtherSwitch service modules, although the show 
version output always shows the software image running on the switch, the model name shown at the 
end of this display is the factory configuration (IP base image [formerly known as the SMI] or IP 
services image [formerly known as the EMI]) and does not change if you upgrade the software image.

You can also use the dir filesystem: privileged EXEC command to see the directory names of other 
software images that you might have stored in flash memory.
