I have a 6509 with redundant SUP720-PFC3-MSFC3.
The standby SUP goes to rommon any time the Catalyst is powered off and on again.
Then when I type the boot command
it boots normaly, retrieving the booting string with the path/name of the image.And then, it runs fine.
But it is faulty again if I ever unplug the card off and on again from its slot.
Of course, I've set the config-reg to 0x2102 through configuration mode in IOS. When the SUP720 is in Rommon, I did the same with the rommon command "confreg". I even copy the rommon environment to nvram with the rommon command "sync".
But however, any time this card is powered off, it goes to rommon again, on the next power-on.
Can anybody help ?
