Restoring a redundant SUP720

A redundant SUP720 module will not come online and I believe the problem is there is not a valid IOS image on the module's disk0:

I plan to get a CF card with a valid IOS in that slot and reload the module. To restore this module to be SSO redundant to the active SUP720 do I only need to configure it with the redundancy commands listed in the 12.2SX config guide? Will the running config of the ACTIVE SUP720 by sync'd to the standby module?

All you need to do is boot the sup from the CF with the same IOS as the active supervisor. The switch will do the rest as long as the active is configured for SSO. Here are the commands incase you don't have them.


redundancy

mode sso

main-cpu

auto-sync standard
