Hello,

I'm trying to upgrade the above switch from an ipservices IOS to
advanced ip services. The switch does not have enough flash (16MB) to
hold both IOS images. When I try and tftp the new IOS to the switch it
fails on this basis.

What is the best/correct method for performing the upgrade and what
commands are most helpful? I presume that I will need to overwrite the
existing IOS before reloading the switch, which makes me a bit
nervous.

Any ideas will be appreciated,
Thanks

Nick

1)
delete old ios from flash.
use copy tftp: flash: to copy new ios to flash:
conf term, boot system flash flash:newimage
copy runn start
use show bootvar to examine that config-register is 0x2102

2) or use archive download-sw command
