I've taken a standby supervisor out of a 6509 chassis and installed it in a 6504-E chassis.
Couple of problems I observed.
1.switch boots up into rommon mode
2.show mod output shows the sup720 installed into slot 5 of a 6504-E which we all know is impossible as there are only 4 slots.
Some outputs are in the attached file from rommon and from after the switch is started.
any help would be appreciated!
