How would I determine what IOS ver it is running before installing it? My main area of concern is the physicall swap. I just want to make sure I dont need to do anything on the primary before swapping out the standby.
You can verify the IOS with a spare chassis (of course, if you have one).
Another way to do it is break it into the ROMMON of the new card after insertion, and force it to boot from the same IOS via an external CF card. There is a risk to do it on the production box, if you are not sure, you should use the spare chassis instead.
I replaced failed sup card and it booted up with the latest IOS from Cisco, .33 something. It then synced over the config file from the primary. However, it never synced the older IOS image we are running on the primary. So I reloaded the switch and when it booted back up it booted off of our older IOS code. No other issues.
One note: While they were running different IOS version, redundancy mode was rpr but when I synced teh IOS's the mode is now SSO and the standby is HOT instead of COLD.
