I was given a WS-C3560E from a Eng program to configure and redeploy to a new test environment. The switch has not been under maintenance for at least 2 years. I got the switch configured and decided to upgrade the IOS From 12.2.44 to Cisco’s recommended 12.2.55 I thought the IOS copied to flash correctly. I modified the boot record to try first the new IOS, then the old. The boot record updated properly. When I performed the reload the POST went well but when the IOS load was to begin nothing happened for over 5 minutes. I attempted to break-in, but could not and cannot. Less than 30 seconds after a power cycle the Status light stays amber – even when the mode button is depressed and/or powered on overnight. Is the any recourse to modify the boot record to just the old IOS ?
