7600 Password Recovery

After rebooting the SP boots first. One can not send the BREAK signal to drop into rommon mode until the RP has started to boot. The following console message is shown when the RP boots up (which is when one can send the BREAK):

%OIR-6-CONSOLE: Changing console ownership to route processor

Once in rommon enter "confreg 0x2142" then "reset" to set the conf register and restart the supervisor with this new confreg variable and load a blank startup config. Sometimes the RP crashes (and sometimes its a silent crash too!) and that value is lost causing the RP to boot and load the old password protected config again. In this case, when in rommon mode after entering "confreg 0x2142" then enter "sync" and then "reset". If the RP crashes and drops to rommon just enter "reset" again and it should boot with the confreg 0x2142 now.

Once booted don't forget to set the config to 0x2102 so that future reboots will load the startup-config.
