Cisco Cisco IOS Software Release 15.0(1)SE

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.

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.

The upgrade procedures in these release notes describe how to perform the upgrade by using a combined 
tar file. This file contains the Cisco IOS image file and the files needed for the embedded device 
manager. You must use the combined tar file to upgrade the switch through the device manager. To 
upgrade the switch through the command-line interface (CLI), use the tar file and the archive 
download-sw privileged EXEC command.

If you wish to use Device Manager to upgrade the switch from Cisco IOS Release 12.2(35)SE through 
Cisco IOS Release 12.2(40)SE1 (the LAN Base image) to Cisco IOS Release 12.2(50)SE or later (the IP 
base image), you must first upgrade to Cisco IOS Release 12.2(40)SE2.
