My original intention is to upgrade the C4503 IOS with cat4500-ipbasek9-mz.122-54.SG.bin in the Sup II+ engine. The switch said the space is not enough even after I delete one of the old IOS. By deleting the two old IOS and use Copy tftp flashboot, the switch said the space is still not enough too.
I suspect it has to reload but it is too late becaue all the IOS are gone. So, after reload, the switch only boot to ROMMON.
Can anybody help to resolve this problem? Thanks!
