Download your image first, then......

Here is a sample command output to delete a Cisco IOS image (.bin file):

3750#delete flash:c3750-ipbase-mz.122-25.SED1.bin
You can verify the available memory in the Flash file system of both switches individually as this example output shows:

Switch#dir flash1: Switch#dir flash2:


Copy the .bin image from the TFTP server to the Flash file system of both switches.

Note: The Automatic Upgrade (auto-upgrade) feature only works with .tar images.

Switch#copy tftp: flash1:Switch#copy tftp: flash2:

Configure the boot variable to boot the switch with the newly copied IOS:

Switch(config)#boot system switch all flash:/c3750-advipservicesk9-mz.122-25.SEE2.binSwitch(config)#exitSwitch#write memory Verify the boot variable:

Switch#show boot
BOOT path-list      : flash:/c3750-advipservicesk9-mz.122-25.SEE2.bin Switch#reload
Switch#show switch                                              
Switch#  Role      Mac Address     Priority     State
