  • Loaded wrong IOS/2620 router Won't boot.

    I have a c2620 router with a wic2t and 10/100 etho, a console and aux port. I loaded an IOS and and didn't have enough memory. This is the output.

    Smart Init is enabled

    I bought the router from a reseller on Ebay so I don't how to tell which ios is the correct one since I didn't document before I started.

    For anyone else that does this, the work around is to remove the flash and system will boot to rommon and you can then change the confreg to 0 and turn the system off and replace flash. Once that is complete you can continue to reload the correct ios.
