Re: switch 6509 in rommon mode after power outage

  When it is in rommon see what the config register says.  You have switch processor rommon and you have the msfc rommon . If you are checking it when it's already booted completely up then that's msfc . The switch processor rommon must also be 0x2102 , I have seen where it comes right from the factory incorrect.  Also verify your boot statements are correct .  When it boots into rommon , enter confreg 0x2102 , this changes the supervisor config register and then reset  . See if that helps.

this is happening everytime there is power outage, the problem is that we have remote sites with same configuration so if this happened it need me to access the switch console, so can you help what is the cause of this and how to fix?

many thanks
