Hello. I just received some 2800 firewalls from a customer that is needing configured for another customer. I do not have the password to reconfigure it and I have removed the flash card, put an update IOS onto it and a new config file but it doesnt seem to work. I believe the file is loaded into the nvram:start-up and I have no clue on how to blow that out so that I can reset everything. Kind of need to know as soon as possible as I have to get these out soon. Thanks for your time.
Please follow the below procedure:
>> Remove the flash card
>> Boot the router. Router boots up to "ROMMON>" prompt Put the flash
>> card back into the router Enter "confreg 0x2142" and enter Router
>> might ask you to reset. Execute "Reset" or powercycle the router Now
>> router will boot into "Router>" prompt. Execute "enable" command and you will be back in the exec mode with no configuration in there.
>> Execute "config terminal" command. You will get "Router(config)#"
>> prompt Execute "config-register 0x2102" command Execute "exit"
>> command Execute "write mem" command
Now you are set with ability to reconfigure the router.
Hope this helps.
