Since the existing stack and the new one may have different firmware revisions, typically the best route would be to update firmware on the existing stack and then on the new switch to be added before attaching it to the stack. You should not need to do any initial configuring before attaching. As always best practice is to use a ring topology when stacking to avoid split-brain and duplicate IP address issues that are common with daisy-chain failures.
For a fast firmware upgrade, you will need to do a minimum configuration of just an IP address on the out-of-band port, and a user name and password. This will allow you to perform the upgrade with a tftp server.

Thanks Barrett. Can I update the firmware without first configuring? I guess I can look at the manual for the answer to that!
