Cisco Cisco IOS Software Release 12.2(35)SE

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(46)SE or later (the IP 
base image), you must first upgrade to Cisco IOS Release 12.2(40)SE2.

 lists the filenames for this software release. 

Before upgrading your switch software, make sure that you have archived copies of the current Cisco 
IOS release and the Cisco IOS release to which you are upgrading. You should keep these archived 
images until you have upgraded all devices in the network to the new Cisco IOS image and until you 
have verified that the new Cisco IOS image works properly in your network.

Cisco routinely removes old Cisco IOS versions from Cisco.com. See Product Bulletin 2863 for more 
information:

You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a 
host by using the copy flash: tftp: privileged EXEC command. 

Although you can copy any file on the flash memory to the TFTP server, it is time consuming to copy 
all of the HTML files in the tar file. We recommend that you download the tar file from Cisco.com and 
archive it on an internal host in your network.
