replace module of Catalyst 6509

My company has 2 catalyst 6509 and was configured as VSS. And then there is a spare unit of Catalyst 6509 with old configuration. I have cross check the version of 48-port inline cards, 8-port 10Gig module and 720 supervisor engine.
Since my company does not want to buy Cisco smartnet, instead, they perfer to make use the spare unit for any replacement in case of any hardware failure.
I have questions of replacing modules as I am the only one to take care of this.
When 48-port inline card failed, let say, 2 out 3, do I just pull out the failed inline card and replace the one from spare unit? According to Cisco, it's suggested to erase configuration of spare part first and then plug into the production unit. Is this step necessary? after inserted the spare incline card, do I need to configure it or it will be automatically get configuration from supervisor engine?
I would be appreciated if someone could share their experience that would really help.

Line cards do not store a startup config, so they do not have a memory of the previous switch config.  The running switch will remember the removed card, and if the newly inserted card is a different model or revision, the switch will not know how to configure it and you'll need to re-apply the port configs.

Thanks eeRoot! For example, assume that model and revision of inline card are the same, I can pull out an inline card from slot 8 of spare 6509 without requiring any configuration and simply put it to slot 3 of production 6509 for replacement since the inline card in slot 3 was failed. Please correct me if my understanding is wrong.
As you mentioned, if the card is different model and revision, I can still use it but require to manually configure it. Do you mean supervisor engine will be recogoize this replacement card? Would you mind to share what needs to be configured and would it be impacted to original running-config that stored in supervisor engine?

If the new card is a different mode, then you need to check Cisco's website and verify that your version of IOS will recognized the new hardware.  There are hardware compatibility lists for IOS versions and the various module cards.

Before removing the old card, you can use the default interface command to blank the port configs.  Then swap the cards.  Then use the "show module" command to verify that the new line card is recognized and active (usually takes 20 - 30 seconds).  Then configure the individual ports as needed.
