Hi to all,
Sorry to say this but I had accidentally deleted the old IOS image on my 3550 switch before uploading the new one. Now when the switch starts, it will always says boot failed and go to the "switch" prompt. This is the first time I encountered this problem and do not know how to fix it. Can someone help to assist on the problem? I am using only Windows XP Hyper Terminal to access the switch via Console.
Many many thanks,
