Step
1: Make sure the IOS is on the Cisco USB Drive
For this, I am using a Lexar 4Gb drive.
Step
2: Insert drive in the USB port on the back of the switch
Once you are consoled into the switch, you can
insert the USB drive into the back of the switch. There is only one place it
will plug in. You will see "usbflash0: has been inserted" come up on
the screen..
Step
3: Copy the IOS into Flash: on the switch
This is done with the
following command:
Switch# copy
usbflash0:c3750e-universalk9-mz.122-58.SE2.bin flash:
This will copy the
.bin file on the USB into the flash memory of the switch. If you do a "sh flash:" on the switch, you will see both of them listed in
there.

Step
4: Tell switch to boot to the new IOS - and reboot
switch#config t
switch#(config)boot system
c3750e-universalk9-mz.122-58.SE2.bin
switch#(config)exit
switch#reload
switch#(confirm) y
Step
5: Switch boots to new IOS - Remove Old IOS from Flash
Once the switch boots
back up to the new IOS, you can delete the old one out of flash. This is done
with the following command:
switch#delete /recursive /force
flash:c3750e-universalk9-mz.122-55.SE2.bin
