You will need a tftp server on which to put the latest IOS version and to which to can backup the old one. A Windows based one is easy [1]. This assumes that the switch already has an IP set.
1. Determine the boot image on the switch:
switch# show flash
- Backup the flash image to the tftp server
switch# copy flash:flashimagename tftp://ipaddress/flashimagename
- If there is room, leave the old image in place. Otherwise do:
switch# delete flashimagename
- Upload the new flashimage
switch# copy tftp://ipaddress/newflashimage flash:newflashimage
- Make the new image the boot image and reboot
switch# config t switch(config)# no boot system flash:oldflashimage switch(config)# boot system flash:newflashimage switch(config)# exit switch# wr mem switch# reload
